In the dynamic world of machining, efficiency and precision are paramount. Most of the machining allowance is removed during rough cuts. Therefore, increasing productivity at this stage is crucial for reducing the machining costs of the entire manufacturing process. Even with improved capabilities in precise forging, die-casting, injection moulding, and other workpiece production methods that allow for obtaining a workpiece very close to the part's final shape, a high metal removal rate during rough cutting continues to be an important factor in reducing total costs. ISCAR has consistently pushed the boundaries to provide solutions that meet the ever-evolving demands of manufacturing. One of ISCAR's standout innovations is the Fast Feed line of tools designed to enhance productivity while maintaining exceptional precision. Fast Feed tools by ISCAR are designed to operate at high feed rates, significantly reducing machining time and increasing productivity. The concept hinges on the principle of shallow depth of cut combined with high feed, allowing for rapid material removal without compromising surface finish or tool life. This approach is particularly beneficial in roughing operations, where the primary goal is to remove as much material as possible in the shortest time. ISCAR's Fast Feed tools are engineered with advanced geometries that optimise chip evacuation and reduce cutting forces. This results in less wear and tear on both the tool and the machine, extending their lifespan. The Fast Feed tools are suitable for a wide range of materials, including steels, stainless steels, cast irons, high-temperature superalloys (HTSA), and titanium. This versatility makes the tools an attractive option for industries such as aerospace, automotive, and mould and die, where diverse materials are often encountered. By allowing for higher feed rates, Fast Feed tools significantly reduce machining time. This efficiency results in cost savings and increased throughput, which are essential in high-volume production environments. While primarily focused on roughing, ISCAR's Fast Feed tools are also designed to achieve suitable surface finishes, minimising the need for secondary operations and further enhancing productivity. The combination of advanced cutting tool materials, wear-resistant coatings, and optimised geometries ensure that Fast Feed tools have a long tool life, even under the demanding conditions of high-speed machining. Fast Feed tools are making significant impacts across various industries. In aerospace, where difficult-to-cut materials like titanium and HTSA are common, these tools help address the challenges of machining tough materials. In the automotive sector, they enable manufacturers to meet the fast-paced production demands while maintaining high quality. The mould and die industry also benefits from reduced machining times and improved surface finishes, which are crucial for producing complex shapes with high precision. ISCAR offers a comprehensive selection of advanced cutting tools, including fast-feed turning and grooving tools. These tools are designed to enhance productivity, efficiency, and precision in various machining operations. Fast Feed Turning Tools (Fig.1) l High Feed Rates: These tools enable increased feed rates, thereby reducing machining cycle times. l Durable Materials: Constructed from high-quality materials to withstand high-speed machining conditions. l Precision Cutting: Engineered for accuracy, ensuring precise cuts with minimal tool wear. l Versatility: Suitable for a variety of materials and applications, offering great flexibility. Fast Feed Grooving and Parting Tools (Fig.2) l High-Speed Performance: Designed to perform at high speeds, improving the overall efficiency of grooving operations. l Reduced Cycle Times: High feed capabilities allow for quicker material removal, reducing overall cycle times. l Enhanced Tool Life: Made from durable materials that extend the life of the tool, even under demanding conditions. l Consistent Quality: Ensures consistent performance and high-quality results in various grooving applications. ISCAR also provides an extensive range of fast feed milling tools designed to significantly increase efficiency and productivity. These tools are specifically engineered to deliver high material removal rates and reduce cycle times in various milling operations. Fast feed (FF) milling cutters are a key factor in high feed milling (HFM) techniques. The cutter geometry, designed for efficient chip thinning, must ensure the correct distribution of the cutting force. There are two principal geometrical approaches. The first design requires the cutting edge of an FF milling cutter to be an arc of a circle. Another concept is based on using one or two straight edges that are chords of the arc. In both cases, the small cutting edge angle (usually 9-17°) meets the requirements of chip thinning and decreasing the total bending load on a tool. Ensuring the geometry of solid carbide fast feed endmills and replaceable milling heads demands the specific shape of a cutting edge, while in indexable milling, it may be provided by the appropriate location of an insert of even a simple profile. Although the introduction of innovative grades and advances in chip forming rake faces have improved progress in FF milling cutters, the essential element, the geometry, remains constant. If the cutting edge of an FF milling cutter is the arc of a circle (or the chords that approximate the arc), the cutting edge angle of the cutter is not a constant value but varies depending on the axial depth of cut from 0 to the mentioned 9-17°. In milling, the chip thickness is a function of the tool's cutting edge angle. Under the same conditions, the smaller the cutting edge angle, the thinner the chip. Therefore, the programmed feed should be increased correspondingly to produce chips of the required thickness.

Difficult-to-cut materials are defined as engineering materials with significantly lower machinability than typical. These materials are often referred to in shoptalk as ‘hard-to-machine,' ‘tough-to-cut,' or even ‘nasty.' It is important to note that high hardness is not the only characteristic that makes these materials challenging to machine; several other factors contribute to their machining difficulties. Every industrial branch, in one way or another, must deal with such materials. However, the leading consumer of these materials is the aerospace industry. It is in this sector—whether in the production of turbine engines, landing gear components, or primary airframe elements—that difficult-to-cut materials have found their most significant application. In the aerospace industry, the key characteristics of required materials are strength-to-weight ratio, robustness, fatigue life, and resistance to corrosion and hot temperatures. It turns out that materials meeting these characteristics are difficult to machine, posing a serious challenge for production. When speaking about such materials, the following information should be considered: l High-alloy high-strength steel, l Titanium alloys, l Hot temperature superalloys, l Composites. High-strength steels are used in elements subjected to extreme mechanical load, such as landing gear. They are also the primary material for various fasteners. Titanium alloys, with their excellent strength-to-density ratio, high corrosion-proof, and creep resistance, have become the preferred material for producing the main parts of a jet engine's cold section. These alloys also provide a suitable alternative to steel and stainless steel for weight savings. Hot-temperature superalloys (HTSA), which can maintain their strength in high-temperature environments, are common in the components of a jet engine's hot section. Composites offer impressive specific strength, helping to decrease an aircraft's weight and opening new prospects for aerodynamic fairing. In military aviation, composites contribute to improved aircraft's stealth characteristics. However, machining these materials presents numerous challenges for several reasons. The main challenges are as follows: l High material strength results in significant cutting forces that increase the mechanical load on the cutting tool. l Intensive heat generation and low thermal conductivity of the material (for example, when machining titanium alloys) cause poor heat transfer. This leads to a growing thermal load on the tool and increases the risk of build-up on a cutting edge. l Work hardening of materials (specifically HTSA) increases the strength and hardness of the workpiece surface during cutting, making machining difficult. l The high abrasion factor (when machining composites) intensifies the galling of the tool's active area. Additionally, other specific material features affect machinability. For example, the ‘springiness' of titanium alloys contributes to vibration, worsening machining accuracy and surface finish. The inner structure of composites is associated with material delamination during machining. All the mentioned aspects accelerate tool wear and diminish tool life. The trends in the aerospace industry distinctly point to the increased usage of difficult-to-cut materials. This is manifested by introducing new alloys with higher strength and heat-resistance characteristics, the broad application of composites, and the utilisation of hybrid-structure (metal-composite) materials. To meet these challenges, the metalworking industry introduces new cutting strategies based on the impressive capabilities of modern CNC machines and CAM systems. However, the cutting tool is the final link in the entire machining chain, which directly contacts the material and removes its layer during operation. This link is the most ‘conservative' part of the chain, and its development is slow, often hindering the full utilisation of advanced machines' capabilities. To overcome the existing difficulties, it is necessary to reduce machining data, which leads to low productivity and increased machining costs. Understandably, every step forward, even a small one, in the tool field can significantly improve machining ‘nasty' materials. Therefore, the metalworking industry welcomes the latest advances in cutting tools, hoping they will radically change the situation. What are the main requirements for tools intended for efficient machining of tough-to-cut aerospace materials? In brief, they need to be hard, durable, and precise to enable productive machining while ensuring predictable and stable prolonged tool life and the required accuracy level. However, meeting these understandable and reasonable demands requires significant efforts, and even small progress in this direction faces challenges. Every new advance involves serious R&D work and extensive testing. Hence, tool development focuses on the following areas: Cutting material grades. Tool design. A tool's digital component. The emphasis in cutting materials is on improving hardness, wear resistance, and high-temperature strength. This is achieved by introducing new coatings, particularly those based on nanotechnology, and expanding the use of extra-hard cutting materials like cubic boron nitride (CBN) and ceramics. In tool design, enhancements optimise macro and micro-geometries, such as the cutting edge design and cutting edge preparation, to improve cutting capabilities. Computer modelling, combined with computational dynamics and the impressive possibilities of additive manufacturing (AM), provides new opportunities for shaping flutes, chip gullets, and internal coolant channels. This contributes to better chip evacuation and coolant supply, improving tool performance. A key area is increasing the vibration resistance of the tool through advanced cutting geometry, enhancing the rigidity of the tool structure, and using vibration-damping toolholders. The tool's digital component includes the digital twin and various software products, which allow for virtual assembly, machining simulation, cutting data selection, tool life estimation, and necessary calculations such as machining power and cutting forces. ISCAR expects that this component will be compatible with data exchange standards to meet the requirements of Smart manufacturing. The noted trends are evident in the new developments from ISCAR, one of the leaders in tool manufacturing, presented within the framework of the latest LOGIQUICK campaign. The company has introduced two new carbide grades with PVD coating: IC1017, which ISCAR created for turning Ni-based HTSA, and IC716, which is intended for high-performance indexable milling titanium alloys. The range of chatter-dampening solid carbide endmills has been expanded with contemporary designs made from the bronze-coloured IC608 carbide grade, which is the first choice for the ISO S group of applications (cutting superalloys and titanium). Another carbide grade, IC5600, has been developed by ISCAR's prolific R&D Materials Sciences engineers for milling steel (ISO P group). The combination of the grade's submicron substrate, CVD coating, and post-coating treatment aims to enhance resistance to abrasive wear and thermal loading, increasing cutting speed, particularly when machining high-strength steel. CERAMILL, a new family of endmills with indexable single-sided round inserts (Fig. 1), is interesting from two points of view. First, the family utilises an ingenious mechanism for high-rigidity insert clamping. This mechanism allows for an increased number of teeth compared to a typical design of similar tools in the same diameter. Additionally, it enables simple indexing and insert replacement without removing the endmill from the toolholder. Second, the inserts are produced from ceramic grades specially engineered for machining HTSA. ISCAR has expanded its range of anti-vibration products based on the innovative built-in damping mechanism, which features a heavy mass supported by a rubber spring element containing oil for enhanced dampening. The turning line now includes vibration-absorbing boring bars for machining depths of 12 and 14 times the shank diameter (Fig. 2). Additionally, the milling line has incorporated anti-vibration shanks with MULTI-MASTER adaptation. The QUICK-X-FLUTE is a family of extended flute shell mills developed to achieve high metal removal rates (MRR) in rough milling of challenging materials such as HTSA and titanium (ISO S), austenitic and duplex stainless steel (ISO M), and steel (ISO P). These ‘porcupines' utilise cost-effective, double-sided square inserts with 8 indexable cutting edges. A key aspect of the mill design is the optimised flute geometry (Fig. 3), which balances mill rigidity and the necessity for adequate chip flow when cutting at high MRR. The QUICK-X-FLUTE mills also feature an inner coolant supply option. Using high-pressure pinpointed coolant with replaceable nozzles and face frontal outlets ensures a direct supply of coolant to the cutting zone. This enhances the cooling and lubrication action, contributing to optimal chip control. Effective coolant supply has become a primary emphasis in contemporary tool designs. In the PICCO line of miniature turning tools, ISCAR has introduced new inserts with internal coolant channels (Fig. 4). In hole making; the company has unveiled new 3-flute solid carbide drills for machining flat-bottom holes featuring three coolant outlets. The latest additions to tool holding include holders with coolant channels along the shank bore. Additionally, in ISCAR's classical HELIMILL indexable milling family, the company's R&D engineers have upgraded the design to maximise flow rate with minimal pressure drop using computerised fluid dynamic (CFD) software. Improvements have also been made to NEOITA, an integral part of the company's digital tool component. NEOITA, an expert system that recommends optimal tooling solutions and forecasts tool life for a specific application, now includes new features. One of these is the AI-powered information search, specifically designed to retrieve detailed data on workpiece materials, including their metallurgical composition and typical uses. Enhanced performance in machining difficult-to-cut aerospace materials is a complex challenge. Tool manufacturers continually strive to provide more advanced and productive solutions to address this. While no radical breakthroughs have been observed, recent developments indicate steady evolutionary progress in this area.
Milling originated in the late 18th century and quickly became one of the primary machining technologies. Nowadays, it is easier to imagine any machine shop with milling operations on the shop floor; it's an essential process in manufacturing. The increasing demands of manufacturing drive this integral part of machining technology. However, there are specific aspects that uniquely impact the advancement of milling. We are witnessing significant changes in manufacturing that will have profound consequences on the development of milling directions. These changes are driven by various factors, such as the increasing accuracy of metal forming through precision investment cutting and precision forging, the widespread adoption of 3D printing, and the growing usage of new composite and sintered materials. Furthermore, there is a need to enhance productivity in machining hard-to-cut superalloys and titanium grades, and the strong focus on electric and hybrid cars in the automotive industry contributes to these changes. In addition, advancements in multi-axis machine tools have opened new possibilities for the precise machining of complex parts and enabled the implementation of new cutting strategies to improve productivity. In modern technological processes, there is a tendency to significantly reduce the machining stock intended for milling operations while simultaneously increasing the requirements for surface finish. Therefore, the advancement in milling is driven by the need for higher productivity, precision and sustainability in milling operations. Consequently, the main developments can be characterised as follows: Fast metal removal focuses on boosting the metal removal rate (MRR) to achieve higher productivity by significantly increasing cutting speed or feed per tooth. This is achieved through techniques such as high-speed milling (HSM) and, in rough operations, high-feed milling (HFM). Precision milling provides higher accuracy in milling operations. The utilisation of multi-axis machining centres characterises multi-axis milling to enable complex milling operations. Adaptive milling aims to develop intelligent systems that can adapt to changing conditions during machining. Sustainable milling strives to reduce the environmental impact of milling operations. It involves developing eco-friendly cutting fluids, recycling and reusing materials, and using energy-efficient machine tools and milling cutters. Success in these areas relies on the synergy of several key components: machine tools, cutting tools, and CAM systems. High-speed milling necessitates machine tool technologies capable of handling exceptionally high rotational velocities and advanced cutting materials and coatings for milling tools. Simultaneously, enhancing the precision of milling operations requires milling cutters with tighter tolerances and improved control systems and linear motor drives. In the case of multi-axis milling, the breakthrough lies in effectively controlled axes movement, along with the application of appropriate cutting geometries for milling tools. On the other hand, adaptive milling incorporates innovations such as using state-of-the-art monitoring systems, high-sensitive sensors, and efficient algorithms to optimise cutting data and tool paths in real-time. Moreover, sustainability advancements require energy-efficient milling strategies that employ suitable machine tools, cutting tools, and eco-friendly coolant techniques. Indexable milling reflects the advancements that feature exchangeable cutting inserts in machining operations. a) Advanced insert materials are an ongoing process to improve the cutting materials for indexable milling inserts, including the development of advanced carbide grades, ceramics, and ultra-hard cutting materials. b) Coating technologies with continuous R&D focus on new coatings to improve wear and heat resistance while enhancing lubricity. c) Progressive cutting geometry optimises cutting geometry and chip forming topology of inserts to improve cutting action and diminish cutting forces and chip flow in milling operations. d) Effective cutting material uses an intelligent insert design to provide maximum indexable cutting edges without reducing cutting capabilities. In addition, the distinct course on smart manufacturing requires the integration of digitisation into milling operations and tools. Regarding tools, digital twins and software applications have already become a ‘must' feature of a comprehensive tool range. How can cutting tool producers rise to the challenge? Which milling tool solutions will provide the right answer to the emerging trends? Is the field of cutting tool manufacturing, often considered conservative in metalworking, capable of delivering a timely response to current demands? The recent advancements from ISCAR provide greater insights into these subjects. High-speed trochoidal milling involves following a curvilinear tool path to maintain a constant load on the cutting edge to eliminate spikes in load during material entry. This strategy is efficient for milling deep slots, pockets, and cavities. Additionally, trochoidal milling has shown excellent results when working with challenging materials such as high-temperature superalloys. The CHATTERFREE EC-E7/H7-CF is a new family of multi-flute endmills for trochoidal milling techniques. The family's geometric design includes different helix angles and variable angular pitches to improve dynamic behaviour. These endmills are available in a range of length-to-diameter ratios (Fig. 1). Machine tools allow highly productive milling of aluminium alloys at extreme spindle speeds, reaching up to 33,000rpm. To meet this challenge, ISCAR has developed 90° indexable milling cutters that accommodate large inserts for a depths of cut up to 22mm (Fig. 2). The cutters have been designed to eliminate insert radial displacement, which may occur due to the high centrifugal forces generated during very high rotational speeds. High-feed milling (HFM) has become a widely adopted method for efficiently rough machining complex and flat surfaces. ISCAR offers a comprehensive range of HFM products to meet the demands of various industrial applications. Recently, the range has been expanded with new additions. The LOGIQ-4-FEED family of HFM tools, featuring specific bone-shaped inserts (Fig. 3), now includes tools with larger inserts. These new products significantly broaden the application range, particularly in the mould and die industry's high-feed milling of large-sized cavities. Another addition is NEOFEED, a family of HFM tools with double-sided inserts, providing eight cutting edges for improved cost-effectiveness. Advancements in multi-axis machine tools and CAD/CAM systems have given rise to precise milling of complex shapes with minimal machining stock, using segment or barrel-shaped endmills. ISCAR's program for these endmills encompasses three design concepts: a solid carbide design, an exchangeable MULTI-MASTER head, and a one-insert approach (Fig. 4). When milling high-temperature superalloys, cutting ceramics can substantially increase cutting speeds, reaching 1000m/min. ISCAR's latest ceramic tools include ceramic solid endmills and indexable milling cutters with double-sided round ceramic inserts. The double-sided design aims to maximise the utilisation of ceramic material grades, such as ‘black' ceramic, whisker-reinforced ceramic, and SiAlON (a silicon-nitride-based ceramic). These selected examples serve as good illustrations of the main directions of advancement in milling tools. As new demands arise, new solutions are required, and these new challenges will fuel the search for innovative tool designs.
The design concept of assembled drills with exchangeable solid carbide cutting heads, adopted by ISCAR at the turn of the century, significantly altered the company's holemaking product program. As part of this concept, a precise carbide head is mounted in a steel holder using the ‘self-clamping' principle, which relies on the holder's elastic deformation without any mechanical clamping means. This approach is characteristic of various successful ISCAR products, such as the SELF-GRIP and MULTI-MASTER tool lines. These have substantially improved machining performance and revolutionised traditional perspectives on cutting tool design. This is complemented with stoppers and locking sections for reliable security. In the assembled drills with carbide heads, the cutting head has a specially shaped rake surface to optimise chip formation and a centring area to ensure high accuracy. The drill body is produced from a high-strength steel grade and features the innovative design of the head pocket, helical flutes, and internal channels for coolant supply. Advancements in technology, particularly in powder metallurgy processes and CNC machining, have made this design feasible. The concept of assembled drills with carbide heads guarantees several key advantages: 1. With a rigid structure, reliable clamping principle, unique cutting geometry and advanced carbide grade of the heads, the drills guarantee productive results. This significantly reduces cycle times and enables high-quality holes. These drills can be used for machining a wide range of materials, including steel, stainless steel, cast iron, titanium and high-temperature alloys. 2. High repeatability and ISCAR's ‘no-setup-time' principle promise that a worn head can be replaced without removing the drill from a machine, eliminating additional setup operations and considerably decreasing downtime. The simple change of the heads makes the drills user-friendly and easy to handle. 3. The drills are available in a wide range of diameters and overall lengths to suit various applications. 4. The use of interchangeable heads diminishes the need for a large drill inventory. ISCAR's drills with exchangeable carbide heads provide customers with a valuable tool solution to enhance the profitability of holemaking operations. Over the past 20 years, these drills have undergone significant changes. Beginning with the CHAMDRILL family, each new phase in the concept's enhancement has led to new products that outperform their predecessors. Today, SUMOCHAM is ISCAR's most popular family of assembled drills with exchangeable carbide heads and is highly regarded by customers. The continuous search to increase drilling productivity, mainly when machining materials that produce fine chips, has created the LOGIQ-3-CHAM – a family of three-flute drills that utilise the same self-clamping approach. ISCAR's development of carbide-headed drills continues to aspire. Unsurprisingly, ISCAR's latest product campaign, LOGIQUICK, has unveiled innovative designs that enrich the existing product families, broaden their scope, and pave the way for new application areas. The new holder with three flute heads allows a 10:1 drilling depth-to-diameter ratio. The holder's main feature is a specific flute design that minimally affects the tool's structural strength. Another innovation is the expansion of the LOGIQ-3-CHAM family application to include counterboring. The specially designed three-flute heads are mounted on existing tools and transformed into highly efficient counterbores. The unique design features of the heads include a corner chamfer for rapid chipping, specialised deflectors for improved chip formation and a unique margin for enhanced support and guidance. This significantly boosts performance when machining materials like sticky steel, stainless steel and high-temperature superalloys. This design facilitates a broad spectrum of counterboring operations, ensuring high-quality holes, even when machining cross-holes with inclined surfaces. The CHAM-SPADE-IQ is a new family of holemaking tools with exchangeable heads. Introduced as part of the LOGIQUICK, the family provides a solution for drilling steel profile construction beams. Machining beams often occurs under non-rigid conditions, presenting a significant challenge for manufacturers. To address this issue, drilling tools must have an adaptive cutting geometry to compensate for the lack of rigidity. The newly introduced family, dedicated explicitly to profile construction, includes two flute carbide drilling heads and reinforced steel holders. The heads feature a specific self-centring cutting edge for secure hole penetration and sharp corners to prevent deformation. The holders' durable structure maximises the tools' dynamic stability when drilling at a depth-to-diameter ratio of up to 5. New drills with MULTI-MASTER adaptations that carry exchangeable carbide heads essentially serve as a ‘bridge', connecting the successful SUMOCHAM and MULTI-MASTER families. The drills are a component of a versatile modular tool assembly that allows the mounting of drilling heads on a wide range of MULTI-MASTER tools. This facilitates an easy and quick change of the heads and the drill bodies. Moreover, the modular concept provides straightforward customisation and flexibility regarding overall length and diameter and finding the optimal tool configuration. It's worth noting that the holemaking innovations in the LOGIQUICK campaign aren't solely represented by assembled tools with exchangeable heads. Several products of another design concept can also be highlighted. The three-flute flat-bottom solid carbide drill with internal coolant channels is one such product. The drill features a small isle for improved penetration, wavy cutting edges for assured chip control, an optimised core diameter to increase tool rigidity, and narrow wiper sections to reduce friction. This improves surface finish and combines with an internal coolant supply that extends tool life and improves chip evacuation. These incredible attributes contribute to the promising prospects of this product line. In the boring line, a new series of boring heads with extra fine digital adjustment has replaced the existing heads with an MB connection. In the milling line, the portfolio has been enhanced with the addition of the The QUICK-D-MILL is a family of multi-functional indexable cutters. These versatile ‘all-in-one' cutters are suitable for various machining applications, embracing the milling of shoulders, slots, and pockets and drilling flat-bottom holes. The overview of the mentioned products highlights that ISCAR's focus on holemaking continues to drive its development efforts. With the metalworking industry seeking solutions to enhance holemaking performance, ISCAR is confident that its latest LOGIQUICK drilling developments will effectively meet the industry's demands.

Many people regard the lathe as the forerunner of modern machine tools. Its introduction which made turning operations possible, marked the dawn of machining. Today, turning is still one of the most commonly used machining processes, and lathes remain a substantial part of global machine tool sales. This is why turning tools make up a considerable portion of the product range for leading cutting tool manufacturers. It is not surprising that LOGIQUICK, ISCAR's latest campaign, brings new developments to the market with a significant focus on innovation in the field of turning. Some of the newly introduced products extend the existing families within ISCAR's turning line, while others offer solutions for advanced manufacturing. Such novelties not only reflect the trends of modern metal cutting but also aim to enhance the profitability of machining operations, particularly in turning. Several key features characterise the development directions in turning tools and this includes the following: • Higher Efficiency and Precision: This involves turning tools that can enhance productivity and precision, accelerate the overall machining process and minimise waste. • Advanced Cutting Materials and Progressive Coating Methods: Cutting-edge materials such as ceramics and cubic boron nitride (CBN) are becoming more common in turning tools. Through excellent heat resistance and durability, these extra-hard materials offer superior cutting speed when compared to traditional tungsten carbide. Concurrently, the need for rapid metal removal is driving interest in progressive coating technologies for cemented carbides. Innovative coatings can enhance cutting capabilities, extend tool life, and reduce wear. • Multi-Directional Turning Tools: These high-quality, versatile tools not only increase productivity and machining efficiency by reducing the number of tool changes but also minimise tool inventory, decrease machine downtime and maintain tighter tolerances. • Digitalisation: The Industry 4.0 approach underscores the importance of a turning tool's digital impact as an integral part of smart manufacturing. • Sustainability: Given the pressing nature of environmental issues, there is a growing demand for cutting tools that have a smaller environmental impact. This means they should be less energy-intensive and generate less waste. With the above in mind, the new products in ISCAR's turning tool line that are part of the LOGIQUICK campaign accommodate these criteria. Indeed, turning encompasses many external and internal machining applications, including longitudinal turning, facing, profiling, chamfering, grooving, parting and boring. Let's study ISCAR's most recent turning advancements and highlight their features. Advanced Cutting Material to Boost Turning Efficiency ISCAR has significantly broadened the range of available ceramic grades for ISO-standard turning inserts. The recent additions to the range have been designed to facilitate efficient machining of difficult-to-cut materials, particularly hard steel and cast iron (ISO H group of application). The newly introduced IC1017 carbide grade was specifically developed for machining challenging nickel-based superalloys. This complementary grade features a high-hardness submicron substrate and a PVD coating to enable turning superalloys at higher speeds. For cutting non-ferrous materials such as aluminium, copper, platinum, bronze, brass, and others (ISO N group of application). The product range has been enhanced with new turning and grooving inserts featuring a nano-composite diamond-like coating (DLC). Multi-Directional Benefits QUICK-T-LOCK is an innovative tool family designed for productive multi-directional cutting. This includes front and back turning, profiling, and facing operations, all achievable with just one tool. The family uses a new insert-clamping concept to provide exceptional stability during machining at extremely high feed rates. A notable feature is the advanced chipformer, specially designed for high-feed turning, especially in backworking machining (Fig. 1). V-shape CUT-V-GRIP inserts offer a versatile solution for bi-directional external turning operations. The inserts, suitable for installation on modified existing holders, are capable of entering narrow machining areas where common V-type ISO inserts cannot be used (Fig.2). The Boring Line When boring with a long overhang (usually more than five times bore diameters), vibration is a common issue. These vibrations can affect surface finish, reduce tool life, increase power consumption and limit performance. While changing cutting conditions is a typical method to reduce vibrations, it may not always be the best solution, as it can result in longer machining time. However, a new anti-vibration holder with an active vibration-damping mechanism offers an alternative approach to overcome this challenge. It enables a high level of productivity in various boring operations, from rough to finish. ISCAR's PICCO is a tool system primarily designed for machining small parts. This versatile system, which can be applied to a wide range of turning, boring, threading and drilling operations, is highly popular in workshops that manufacture various miniature components. A typical PICCO tool consists of a holder and a solid carbide cutting insert secured within the holder. The system has now evolved with the introduction of PICCO-INDEX, a family of steel and carbide boring bars designed to be mounted on existing toolholders. The bars are specially engineered to carry small ISO-standard indexable inserts (Fig. 3). The new addition offers a viable cost-effective alternative, particularly for rough and semi-finish operations for compact part production. Swiss-Type CNC Swiss-Type turning centres play a crucial role in modern manufacturing due to their precision, efficiency and ability to perform multiple operations simultaneously, such as drilling, milling, turning and knurling. They are instrumental in the production of miniature components required in several industries. This includes watchmaking, medical devices, automation equipment and electronics. Consequently, the development of more advanced cutting tools and toolholders dedicated to Swiss-Type lathes is a top priority for most tool manufacturers, including ISCAR. The LOGIQUICK campaign has also highlighted Swiss-Type machining tools. The new modular system, QUICKSWISS, provides a solution for most applications on the sub-spindle of Swiss-Type lathes. This system (Fig. 4), which features a height adjustment option, offers a wide variety of bases, holders, and heads for various turning operations. For grooving, parting, and recessing, the QUICK-2-CUT family shows promise. The tools in this family carry high-precision, narrow, double-sided inserts which are tangentially mounted on the tool from the side. The insert clamping concept ensures high rigidity and excellent dimensional repeatability. The targeted coolant, directed to the cutting zone, improves tool life and contributes to a better surface finish (Fig. 5). The LOGIQ-4-TURN family of turning tools with indexable double-sided inserts has been well-received in the market. In response to this positive feedback, the company has expanded the family range to include smaller-sized inserts, providing a cost-effective solution for Swiss-Type and compact lathes. In ISCAR's electronic catalogue, two new filter search options specifically related to Swiss-Type lathes have been added. These options allow for the search of modular adaptations to find more efficient tools for main and back tool posts. The LOGIQUICK campaign's turning package encompasses far more than the products currently under consideration. The company is gradually introducing new product families in quick succession and plans to allocate more time to analysing these new arrivals. Will they boost productivity and contribute to a rapid increase in customer profitability? ISCAR firmly believes the answer is a resounding ‘yes'.
The introduction of the ISCAR HELIMILL in the 1990s marked a significant milestone in milling tools. It changed the design of milling tools with indexable inserts, establishing a new approach that would help to shape the industry. The breakthrough was achieved using a parallelogram-shaped carbide insert, featuring a helical cutting edge formed by the intersection of the insert's helical side and shaped top surfaces (Fig. 1). The HELIMILL concept offers several advantages. Firstly, the consistency of the rake and relief angles along the insert's cutting edge, when mounted on a tool reduces cutting force variations and ensures a smooth cutting action. Secondly, the uniformity of the insert's cutting wedge enhances its strength. Lastly, the helical cutting edge's proximity to the imaginary cylinder generated by a rotating tool improves accuracy compared to the straight edge found in previous-generation milling inserts. These advancements have elevated milling performance. Over the years, continuous improvement has led to significant changes in the HELIMILL inserts. The helix of the cutting edge has become more aggressive, and the top surface topology has become more intricate. Combined with advanced carbide grades, these new designs have ushered in a new level of performance. However, the parallelogram insert shape limits the number of indexable cutting edges to two. To maximise the efficiency of cemented carbides, a new round of insert development was initiated. The successful adaptation of the helical cutting edge to triangular inserts addressed this limitation. The triangular insert concept not only provides three cutting edges but also offers additional benefits. When compared to other shapes with equal cutting-edge lengths, the triangular shape provides a wider central area. This allows for an increase in the central bore size, enabling the use of a clamping screw with a larger thread. As a result, the insert securing is strengthened, contributing to the overall durability of the milling tool assembly. Additionally, the triangular shape enhances the ramping-down cutting capability. Overall, the introduction of the ISCAR HELIMILL and its subsequent advancements have revolutionised the milling tool industry. The use of helical cutting edges and triangular inserts has significantly improved performance, accuracy and durability, pushing milling capabilities to new levels. A proximate successor to the HELIMILL is the HELI-3-MILL, a family of milling tools introduced by ISCAR that features triangular indexable inserts (Fig. 2). The advantages of the ‘helical triangle' highlight why this family has gained popularity in the market. However, it is important to note that this does not mean the triangle shape will completely replace the traditional parallelogram contour with helical cutting edges soon. The parallelogram shape still possesses a competitive edge. Paradoxically, the narrow width of the parallelogram-shaped insert, which is considered a drawback when compared to the triangular shape, also offers certain advantages. Firstly, a narrower insert allows for an indexable design suitable for smaller tool diameters. Secondly, this insert geometry reduces the depth of the chip gullet, strengthening the cross-section of the tool body. This feature is particularly important for extended flute cutter designs where higher strength and rigidity of the body are crucial. The parallelogram insert structure also permits increased corner radii. Additionally, the classical shape is well-suited for high feed milling (HFM) inserts, which can be mounted in existing pockets, effectively transforming a 90-degree tool into an efficient HFM cutter. Moreover, the ‘helical parallelogram' has a smaller overall length compared to the ‘helical triangle' for the same cutting length. Therefore, it would be premature and incorrect to dismiss classical parallelogram inserts. As a result, the development of 90-degree indexable milling cutters harmoniously combines both approaches, utilising both triangular and parallelogram-shaped inserts. While the triangular insert concept dominates modern designs, the parallelogram insert principle remains relevant. The HELIMILL platform continues to be updated with new advantageous products. ISCAR's recently developed products relating to milling cutters with parallelogram-shaped inserts demonstrate that the traditional design approach remains effective and capable of meeting the demands of modern manufacturing. Milling high-temperature superalloys and titanium (ISO S group of applications), as well as difficult-to-cut austenitic and duplex stainless steel (ISO M group), presents challenges. Effective coolant supply, particularly pinpointed high-pressure cooling (HPC), can significantly reduce the heat load on the cutting edge, enhancing lubrication and chip removal. This leads to higher cutting data and enables larger radial engagements, resulting in a higher metal removal rate (MRR). Moreover, HPC facilitates the production of tighter and curled chips, allowing for tool designs with smaller chip gullets and higher tooth density. Taking these factors into consideration, ISCAR has expanded its HELI2000 family (the latest version of the HELIMILL) by introducing new tools that incorporate an HPC option within the tool body. The design of these tools has been optimised using computational fluid dynamics (CFD). They are available in both integral-body configurations and as relatively small-sized exchangeable heads with indexable inserts, which are compatible with ISCAR's modular systems MULTI-MASTER and FLEXFIT (Fig. 3). HELI2000 integrates the HELIMILL and HELIPLUS families, combining their latest developments into a single portfolio. This includes the introduction of two new highly efficient carbide grades: IC5600, designed for machining steel (ISO P group), and IC716, specifically tailored for cutting titanium. Additionally, the insert range has been expanded with new cutting geometries. This includes inserts with a high positive chipformer for milling titanium, chip-splitting cutting edges for productive roughing, and other designs. Furthermore, the range now includes inserts with reinforced cutting edges for high feed milling of hard materials up to HRc 60 hardness (ISO H group, Fig. 4). These new products are also part of ISCAR's HELIALU family, which consists of milling tools with parallelogram-shaped inserts for machining aluminium alloys (ISO N group). The expansion of this family includes indexable endmill heads with threaded adaptations for both MULTI-MASTER and FLEXFIT systems, providing the option for high-pressure cooling (HPC). The screw-in design configuration of the heads significantly enhances the customisation capabilities of HELIALU tools, allowing for a wide range of MULTI-MASTER and FLEXFIT shanks, adaptors, extensions, and reducers to be utilised. Therefore, the development of the ‘helical parallelogram' has not ceased, and the traditional HELIMILL continues to gain momentum. This development follows a gradual upward helix, revisiting past turns but at a more advanced stage.
ISCAR believes it is set to revolutionise metal cutting once again with its latest product launch, the ‘LOGIQUICK'. This new brand signifies ISCAR's new marketing theme and encompasses three keywords: ‘Logic', ‘IQ', and ‘Quick'. The previous campaigns by ISCAR have already highlighted the importance of intelligent cutting tools for advanced machining, providing logical solutions that meet the primary of modern production. With many of these tools becoming a market standard in numerous workshops worldwide, the addition of ‘Quick' in the logo brings forth a sense of anticipation. What new challenges will the campaign products present? Is it simply a catchy brand name or a fundamental concept? Let's explore the meaning of the logo and its implications. In the field of metal cutting, productivity is directly linked to the metal removal rates (MRR). To enhance machining rates, the metalworking industry strives for ‘fast metal removal', which refers to processes that efficiently and swiftly remove material. These processes involve the utilisation of machines, strategies, techniques and cutting tools that enable faster and more effective machining. This reduces cutting time. However, in many cases, the primary obstacle to fully harnessing advanced, highly engineered machine tools and promising machining strategies lies in the cutting tool itself. The cutting tool often becomes the weakest link in the entire machining process, limiting potential gains in productivity and impeding the reduction of machining costs, and the growth of profitability. ISCAR believes that the ultimate objective of a tool manufacturer is to supply cutting tools that ensure efficient metal removal. These tools should not only possess effective working characteristics to enable metal removal rates, but also exhibit qualities such as repeatability, versatility, user-friendliness, and a high utilisation factor. These attributes collectively represent the IQ of the tool, which is essential for leveraging the full potential of advanced machine-tool capabilities. This principle guides the development of cutting tools, harnessing the expertise of tool-design engineers, technologists, metallurgists, manufacturers, and all those involved in creating innovative tool solutions for intelligent machining in the metalworking industry. ISCAR's latest campaign unveils a range of groundbreaking cutting tools, including turning, parting, grooving, hole-making, and milling products. Let's take a closer look at the LOGIQUICK portfolio to fully immerse ourselves in the campaign's essence and delve into the details of these new developments. Rotating tools Steel construction beams play a crucial role in building structures and frameworks, requiring the drilling of numerous holes before assembly. However, the clamping mechanisms on machines often lack rigidity, posing a challenge for drilling. To address these limitations, it is essential for drilling tools to have an adaptive design that compensates for non-rigid conditions, and optimal drilling performance. Currently, finding an efficient drilling tool for beams is a top priority. ISCAR has developed a new solution (Fig. 1) based on the established SUMOCHAM concept of assembled tools with an exchangeable drilling head made from tungsten carbide. This solution incorporates three key elements - the cutting material, cutting geometry and body design. The specially developed PVD-coated IC954 carbide grade offers exceptional resistance to deformation. The new IHP-BP exchangeable head features a dedicated-centring cutting edge, ensuring secure material penetration, while the sharp corners of the head effectively prevent the formation of burrs. Additionally, the reinforced drill body enhances dynamic rigidity. As a result, the new SUMOCHAM product provides an effective solution for drilling relatively thin beam sections under unstable conditions. Introducing another innovative rotating product, the modular SUMOCHAM drill head with MULTI-MASTER adaptation, which combines the strengths of two leading ISCAR product lines. This new drill head is designed to accommodate any of the SUMOCHAM exchangeable heads, providing the versatility of a modular tool assembly. It is specifically designed to be on a wide range of MULTI-MASTER shanks, allowing for easy customisation in terms of shape, overall length, and diameter. This not only reduces the tool inventory but also minimises the need for special drills. The combination of SUMOCHAM and MULTI-MASTER creates a promising synergy effect, offering tremendous potential. Efficiently removing a large volume of material through milling is crucial in the production of critical duty-loaded parts, such as aircraft components made from titanium alloys. Extended flute indexable milling cutters, also known as ‘milling porcupines' are highly effective for this type of machining, particularly when milling cavities, pockets and wide edges. The success of such tools depends on a combination of productivity, reliability, and cost-effectiveness. Introducing the QUICK-X-FLUTE (Fig.2), a new family of 90-degree extended flute shell mills with double-sided square inserts. These mills are designed with an optimised flute shape that strikes a balance between tool rigidity and effective chip flow, enabling high MRR with substantial radial engagement. The developed flute profile enhances vibration resistance, especially during workpiece entry and exit allowing for increased cutting data and improved productivity. The inner channels of the mill have replaceable nozzles and frontal outlets, facilitating direct high-pressure coolant supply (HPC) to the cutting zone. This improves cooling and lubrication, contributing to effective chip control. Additionally, the double-sided square insert offers 8 indexable cutting edges greatly increasing insert material utilisation. Non-Rotating Tools To achieve success in machining high-temperature superalloys (HTSA), the selection of the right cutting tool material is crucial. Introducing IC1017, a new tungsten carbide grade specifically designed for ISO-standardised inserts used in turning HTSA. This grade boasts a high-hardness submicron structure and is coated with PVD enabling higher cutting speeds for enhanced productivity. The LOGIQ-6-TURN (Fig. 3) is a newly designed triangular insert that offers a cost-effective solution for semi-finish and finish turning with a focus on achieving high surface quality. This double-sided insert features a 55° corner angle and positive rake cutting geometry, providing 6 indexable cutting edges. It presents a significant alternative to the standard ISO-type rhombic insert of DCMT type, which only offers 2 cutting edges. One key advantage is the ease with which LOGIQ-6-TURN inserts can be mounted on turning tools designed for triangular TNMG inserts. Maximising profitability through the efficient use of raw materials during the parting process is crucial. ISCAR's highly regarded DO-GRIP parting and grooving family has recently grown with the addition of three new sizes of double-sided inserts. This has been specifically designed for narrow parting operations (Fig. 4). These inserts are primarily targeted for Swiss-type lathes, enabling optimal material savings when parting small-diameter bars, tubes, and thin-walled workpieces. The new tools are just a few examples of the various products introduced by ISCAR as part of the LOGIQUICK campaign. The numerous other product releases have significant interest and will soon be tested by manufacturers. With the increasing demand for quick metal removal, the need for advanced cutting tools continues to grow. This drives the development of tool designs and shapes the logic behind intelligent tool development.

Where Innovation Never Stops! is the slogan that appears on the walls of the production facilities at ISCAR headquarters and has been synonymous with the company for several decades. The Covid-19 pandemic did not interrupt the innovation process, and between 2020-2021 ISCAR introduced the NEOLOGIQ marketing campaign comprised of advanced cutting tools and tooling solutions for modern metalworking. Significant changes in manufacturing, such as intensive digitising, the shift to electric drive in the automotive industry, and growing precise workpiece fabrication, have emerged with new demands for cutting tools. Notwithstanding, the accelerated pace of changes sharpens the demands and requires more ISCAR NEOLOGIQ products that answer to modern-age machining. The CHAM-IQ-DRILL family of assembled drills that mount exchangeable carbide heads, is now upgraded with new heads in the diameter range of 33 to 40mm. These heads can be mounted on any drill possessing the appropriate pocket size. The main feature of the new heads is a multifunctional cutting geometry, which enables effective drilling of various materials such as steel, stainless steel, heat-resistant special alloys, and titanium - assuring hole precision within IT10-IT9 accuracy grades. The ISCAR LOGIQ-3-CHAM is also based on the concept of exchangeable carbide heads with 3 flutes for improved productivity. This is now supplemented by new carbide heads for achieving a nearly flat bottom hole. Flat bottom holes are necessary for screw head sockets, spring seats, washer ports and more. The heads ensure drilling up to an 8XD ratio without a pre-hole. The new design facilitates generating holes with a nearly flat bottom by use of a single pass. The heads are mounted on existing LOGIQ-3-CHAM tools that significantly expand the application range of the family and reduce inventory costs. So, how do you increase the drilling depth? Use a longer drill? The MODUDRILL family of modular drills with replaceable carbide heads carry indexable inserts and provide an alternative solution. Mounting an exchangeable extension holder on a drill body increases the drilling depth by an additional 200mm when machining holes in a diameter range of 33 to 40mm. Key aspects in turning A modular tool concept is the way to reach high versatility. NEOSWISS is a new tool system with quick-change heads that follows this concept. The system is suitable for turning, parting, grooving, and threading applications. By use of a high-clamping-force mechanism, the heads are mounted on a toolholder. The mechanism provides an accurate cutting-edge position each time and utilises high-position repeatability. The system intended mainly for Swiss-type machines enables the removal of heads and replacement inserts within the tight confines of CNC machining centres. ISCAR has developed a new lever dual lock securing mechanism for improved clamping rigidity intended for ISO turning inserts. The new design, referred to as the The LOGIQ-F-GRIP features a new highly advanced tool family for parting solutions. The central component is a robust tool block that mounts on a 4-pocket adapter. There are cases when the rib, a reinforcement element of the block, interferes and prevents clamping the block on typical turret positions. NEOLOGIQ overcomes this problem by providing additional blocks with the rib placed on the alternative side of the block. The revolutionary LOGIQ-F-GRIP parting system was designed to achieve extra stability and vibration-resistant high-productivity parting and grooving operations. The highly engineered LOGIQFGRIP is an assembled tool block that comprises a durable holder and a high-stiffness quad blade with pockets for mounting inserts. The NEODO S890 is a family of 90° indexable face mills for rough and semi-finishing operations. The mills mount durable square double-sided inserts with 8 cutting edges. NEODO S890 facilitates face and square shoulder milling while providing an additional option for milling close to shoulders where there are workpieces or work holding fixture constraints. ISCAR customers have requested additional corner radii and tool diameters, therefore, this tool family was expanded with additional pressed-to-size inserts with a 0.8 mm corner radius and cutters in diameters 32 and 25mm including endmill design configurations. Upgrading toolholders The ISCAR SPINJET family of coolant-driven high-speed compact spindles for small-diameter tools is intended to upgrade existing machines to high-speed performers. It is now supplemented with the Micro 90 intended for miniature rotating tools in milling, drilling, countersinking, thread milling, engraving, chamfering and deburring operations. Micro 90, made of a solid titanium shell and assembled from only six parts, enables rotating velocities that range from 35000 to 53000rpm while the main machine spindle remains idle. The chuck thickness is a factor that limits the working space of a tool. This factor often causes an increase in the tool overhang to reach a machined surface. A novelty in X-STREAM, a family of thermal shrink toolholders, is a series of slim design chucks to eliminate such a restriction. The new chucks follow ISCAR's coolant jet channel technology providing direct coolant supply to the tool cutting edge. Changes in metalworking technology place new demands on cutting tools. To meet these demands, cutting tool manufacturers develop new pr

The history of computer numerically controlled (CNC) machines dates back seven decades. During the 1950s, CNC technology was difficult to introduce due to manufacturers' scepticism. Today, it is hard to imagine the world of manufacturing without CNC machines. In material removal processes, a CNC machine has become the central link that determines the functional capabilities of a manufacturer. CNC machining centres are complex machines that continue to evolve and improve. The advancement of CNC technology is based on the progress in various fields such as the main spindle and its bearing units, machining slideways, high-velocity drives, computer engineering, hydraulics, electric motors, robotics, sensors and much more. When compared to a conventional machine with mechanical parts, the share of modern digital CNC machines is significantly higher. CNC technology will continue to be the backbone of machining methods in the near and far future. The development of CNC machines is intended to increase the versatility, productivity, stability, reliability and accuracy of a given machine. These targets are ongoing milestones that assure contemporary machining results. The leap forward relates to machining centres that combine subtractive and additive technologies that are both CNC machined and 3D printed. At the same time, a complete rethink of CNC advancements has been brought about by Industry 4.0 and the concepts of smart manufacturing. In a smart metalworking factory, there is a continuous information exchange between the real world of CNC machines and the virtual world. This world functions according to the features of the machined parts and their respective theoretical characteristics. Smartly balancing on the boundaries of these worlds and analysing the real-time information is the ability to make decisions and corrections that are made by computer-controlled units. One element that is much smaller, substantially cheaper and considerably less complicated when compared to a CNC machine tool, is a cutting tool. The tool is the link that directly removes material from a workpiece and closes the process loop of ‘machine and workpiece'. Due to objective reasons, the cutting tool element is subjected to less fundamental changes and the cutting tool is frequently identified to be the weakest link in the processes. Something that also limits system capabilities. Therefore, appropriate upgrading of cutting tools should be considered as an integral part of the progress of CNC technology. A conventional approach to making cutting tools relates to designing innovative cutting geometries, using advanced cutting materials and applying leading production technologies that are intended to improve tool life, ensure greater material removal rate (MRR), provide higher accuracy, and increase reliability. Nevertheless, Industry 4.0 trends in the development of CNC technology are placing ever greater priority on the digital component of the cutting tool. Information has constantly accompanied cutting tools even before Industry 4.0. Catalogue data, tool drawings and recommendations regarding applications were provided in printed formats and later in electronic formats and these continue to be essential for the typical metalworking machine shop. Computerisation has affected customer support by providing expanded capabilities in the form of data. Various software applications have enabled the selection of optimal tools and the ability to estimate tool life under specific machining conditions. The combination of ISCAR's NEOITA and its Power Consumption applications enables a quick calculation of cutting forces, bending load and power consumption. It also enables the user to find suitable cutting material grade, the right tool for a specific application and provide an analysis of competitors' products alongside other useful functions. Customers can easily access data and related information through computers and mobile devices, but now, advancements in network communications have introduced the world of metal cutting to the virtual electronic world. Digital twin technologies complement manufacturing processes. Machining modelling, collision checking and process optimising to find the best cutting strategies are only some examples. In a smart factory, the digital twin is the most significant brick of the foundation. Understandably, only a tool having its digital twin is acceptable for the smart factory's toolroom. The progress of CNC technology leads to new demands for cutting tools. A tool manufacturer is expected to be a provider of a product that ideally combines a cutting tool as a material object, its real-time digital twin and an appropriate software environment. This allows the seamless incorporation of the tool data in the CAD/CAM and virtual manufacturing environment, directly transmitted by Internet of Things (IoT) networks - tool packages and virtual assemblies. To make tool representation clear for various computer systems, the ISO: 13399 standard was developed and ensure the platform's independence. This standardisation is necessary for other digital components of the tool package to unify data related to tool life, calculated loads, machining conditions and lots more. ISCAR's digital tool component, which is based on the ISO: 13399 standard, includes the following characteristics: E-catalogue with various search functions, updated promotion information and reference data.

In the metalworking industry, ensuring a high-quality surface finish has always been one of the main focus points in cutting tool development. This is also true for indexable face milling cutters. Despite significant improvements in the high surface quality of milled components, tool designers still believe that available resources have not yet been exhausted and that intelligent applications of the latest generations of advanced milling cutters can substantially improve surface texture further. When considering an indexable milling cutter, the key factors that determine the quality of a generated surface are the cutter's geometry and accuracy. Both characteristics are mainly related to inserts carried by the cutter. Powder metallurgy advancements have enabled the production of carbide inserts with complex shapes to ensure optimal cutting geometries while maintaining substantially increased accuracy of sintered inserts. Not surprisingly, such advancements in technology have significantly improved the surface finish in face milling. However, when indexable milling cutters were successfully applied to machining high-strength materials, and manufacturers started to notice hard milling as an alternative to grinding, the metalworking industry started to demand higher surface finishes through their milling applications – obviously led by the cutting tool. An indexable face milling cutter is a multi-tooth tool. More teeth = more productivity. This is an undeniable advantage of the cutter. But, in terms of surface texture, a large number of teeth may be a problem. A fine distinction in teeth protrusion leads to irregular feed for the teeth and contributes to chatter, which will ultimately affect the surface finish. It is perfectly clear that insert accuracy can considerably be increased by grinding. Moreover, grinding provides a sharp cutting edge that is very important in maintaining cutting action and preventing plastic deformation of the metal in fine milling, which features shallow depths of cut. Ensuring a highly accurate cutting edge requires grinding both the top and side surfaces of an insert. This may cancel the advantages of powder metallurgy in generating complicated surfaces to provide the required rake and clearance angles along a cutting edge. To avoid such an adverse impact, tool engineers should be very resourceful when designing the inserts intended for fine grinding. An important factor regarding the tooth accuracy diminishing is the insert pocket in a cutter that has its own ring a high-quality surface finish has always been one of the main focus points in cutting tool development.

This may cancel the advantages of powder metallurgy in generating complicated surfaces to provide the required rake and clearance angles along a cutting edge. To avoid such an adverse impact, tool engineers should be very resourceful when designing the inserts intended for fine grinding. An important factor regarding the tooth accuracy diminishing is the insert pocket in a cutter that has its own dimensional and form tolerances. As a result, even for ideally precise inserts, teeth protrusion will vary within acceptable limits. Although it cannot ensure an extra fine surface finish when compared to grinding. A way to overcome this problem is by using a fly cutter that carries only one insert. The fly cutter that is successfully used in various milling applications facilitates a smooth and clean cut, providing excellent surface texture parameters. But then again, productivity, in this case, is far below multi-tooth indexable face mills. How do we solve a difficult situation and find an acceptable balance between surface quality and productivity? The cutting tool manufacturer has developed several answers to this challenge. An integrated wiper flat with a specially shaped minor cutting edge is a classical element of various milling inserts. Its width should be greater than the feed per revolution. Despite being called flat, the minor edge sometimes has a complex geometry to compensate for the negative effect of wear development. When an insert is mounted on a cutter, the wiper flat sits parallel to the machined surface. Hence, the surface will be formed by the most protruding insert of the cutter. Introducing a wiper flat in an insert design is an effective way to improve the surface finish. And even today, rough milling inserts may have an integrated wiper. ISCAR's DOVEIQMILL family face mill carries double-sided inserts with a wide wiper flat. These tools are intended for rough and semi-rough milling with a surface roughness that usually features semi-finish to finish passes. The DOVEIQMILL cutters have successfully delivered the hopes of their designers – and the adoption of the cutters in various processes has resulted in the cancelling of finish milling operations. The cutters provide a roughness Ra up to 0.4µm (16µin) when milling steel and cast iron. Increasing the number of teeth in large-diameter face mills and fine pitch cutters determines the appropriate growth of the integrated wiper width, which has a natural bound due to the design and dimensional limitations. In such cases, a high surface finish can be achieved with the use of a specially designed wiper insert (or two inserts for large-sized tools), whereby the wiper flat is significantly wider than the standard one. This insert is mounted in the same pocket but protrudes several tenths of a millimetre axially relative to the standard insert. Very good results can be reached by applying adjustable milling cutters that utilise different mechanisms to adjust the position of an insert cutting edge within very strict limits (only several microns). But the beneficial adjustability of cutting tools also has a flip side as well; it is spider work, which takes time. A desirable solution looks like a tool that after mounting an insert has no adjusting requirements needed to achieve high surface quality grade. That is why improving accuracy and advanced geometries remain the mainstream aim in updating indexable cutters for finish face milling. At the same time, cutting tool manufacturers offer unique solutions that attract attention with their originality. An example is ISCAR's TANGFIN family of milling cutters with tangentially clamped inserts with wide integrated wiper flats. The inserts are positioned in a TANGFIN cutter with a gradual displacement in both radial and axial directions, and therefore, each insert cuts a small section of the machined material providing an extra fine surface finish with roughness Ra up to 0.1μm (4μin). For ensuring a high surface quality in milling relatively small faces, mainly bounded by shoulders, ISCAR has developed dedicated exchangeable solid carbide heads in the diameter range of 12 to 50mm for its MULTI-MASTER and T-FACE families. The heads are fully ground and provide high precision, facilitate a sharp cutting edge and enable a greater number of teeth when compared to mills with indexable inserts of the same diameter. In combination, these features guarantee high-performance and high-quality finish milling. A tendency to decrease machining allowance due to the active introduction of technologies for precise workpiece production and 3D printing makes the issue of obtaining a high surface finish by face milling particularly relevant. Can toolmakers find a prompt, simple, and effective answer to the new needs of manufacturing? As well as having concerns over surface finishing, another issue for the modern machine shop is the selection of the right tool for the right application. Like with the surface finish challenge, it can be difficult for manufacturers to determine whether a standard tool or a special tool is preferable. The ideal tool selection is contingent on various factors, such as the nature of the business situation, the manufacturing program, the production type, and sometimes personal preferences. Standard cutting tools, produced by a specific tool manufacturer, offer high versatility and are appropriate for machining a diverse range of parts that come in different shapes. Furthermore, the tool exhibits excellent performance capabilities when cutting various engineering materials. To ensure seamless production processes, it is crucial to have the cutting tools delivered promptly. This is why standard tools are the foundation of tool stock management on metalworking production floors. A special cutting tool is designed for specific operations on a particular part, made of a specific material, and used on a machine that requires a specific workholding fixture. This custom-engineered tooling solution aims to provide the best possible performance and outcome. However, there is a downside to this solution as it limits the tool's versatility, making it less adaptable to different applications. As a result, special tools are primarily used for high-volume mass production, especially in the automotive industry. Special tools vary in their design complexity. Some are simple modifications of standard tools, such as changes to the corner radius or tool length. These modifications fall under the category of ‘semi-standard' products, which can be manufactured relatively quickly. The design complexity of a special tool is determined by a pre-design study that assesses the customer's manufacturing limitations, accompanied by cost calculations and production time. The results of the study determine the limits and cost-effectiveness that correlate to the special tool's delivery time. However, there are additional ways to reduce the delivery time of special tools, such as using solid tools with exchangeable heads, bodies of indexable cutters, or replaceable inserts. The tool manufacturer's delivery times and production abilities play a significant role in the final decision on how to proceed. One alternative to engineered special tools is modular tooling, such as ISCAR's MULTI-MASTER. It features rotating tools with exchangeable solid carbide heads. This tooling system includes a wide range of tool bodies, adapters, extensions, and reducers that enable the configuration of the required tool for diverse machining operations. Additive manufacturing also presents new opportunities for special tool solutions. This technology allows for the quick production of tools with complex profile designs. Although finish cutting and grinding operations are still necessary, the fast manufacturing of pre-shaped products that are very close to a final shape is fascinating. Additionally, 3D printing can be used to fabricate carbide inserts without the need for a die-set, which significantly reduces production time and costs. This process is an excellent way to create insert prototypes during the development stages and produce low-batch special inserts. AM of carbide inserts and heads is gaining momentum and is highly capable of ensuring fast delivery of customised tools and their components.

Building a house begins with the foundation, its longevity depends on the foundation strength. With cutting tools, this foundation is the material. There are various cutting materials such as cemented carbide, PCD, HSS, ceramics and more. Each type contains different grades. Through history, the introduction of each material and its use has led to a significant change in performance. The last century was marked by the progress of material technology and now, we see fewer new solutions. Does this mean development of new tool materials has already peaked and is experiencing stagnation? No, it is simply that new developments are deep within the cutting material and are focused on its structure. This can be observed only with the help of scanning electron microscopy (SEM), X-ray diffraction (XRD), electron backscatter diffraction (EBCD), and other sophisticated methods. They cover a tremendously complicated world of coatings that is extremely diverse. The most common available cutting material today is cemented carbide, primarily coated. In terms of performance, it represents a balance between efficiency, tool life and cost. Cemented carbide is known also as ‘tungsten carbide’ or simply ‘carbide’. A combination of cemented carbide, coating, and post-coat treatment produces a carbide grade. Only one of these components, the cemented carbide, is an essential element in the grade. Cemented carbide comprises hard carbide particles cemented together by binding metal (mainly cobalt). Most cemented carbides integrate wear-resistant coatings. New developments in cemented carbide are concentrated in three directions, carbide production, advanced coating methods and innovative post-coating techniques. Considerable success has been achieved in each direction. This is reflected in the wealth of new products introduced to the market. Customers analyse grades using parameters such as productivity, tool life and performance. In upgrading carbide grades, ISCAR is very sensitive to the challenge faced by industry. In this context, ISCAR’s solutions are developed considering the trends of modern metalworking. For example, titanium and superalloy use has increased. The growing usage demands technological solutions. The new tools require an appropriate foundation, made of advanced materials to achieve the desired cutting geometry. And for the construction of this foundation, ISCAR offers its new effective ‘bricks’ – upgraded carbide grades developed by metallurgists in the last few years. In milling, ISCAR has developed PVD coated IC882 and CVD coated IC5820 grades– two chocolate-color carbide grades for cutting titanium, high-temperature alloys and stainless. An integral component is a post coating treatment that facilitates longer tool life, due to increased resistance to chipping, notch wear, and build-up edge formation. The IC882 grade demonstrates impressive performance when machining conditions are hard, and the advantages of the IC5820 are most fully manifested when applied to milling with pinpointed high-pressure coolant supply. The PVD coated carbide grade IC806 was designed especially for turning high-temperature superalloys. As a result of the high mark that the grade received from the manufacturers of aerospace components, ISCAR expanded the application range of IC806 for laydown threading inserts. In addition to cemented carbide, industry consumes other hard cutting materials such as ceramics, diamond and cubic boron nitride (CBN). Their application on difficult-to-cut materials facilitates considerable increases in productivity. In recent years, ISCAR has enriched its cutting material range by introducing several new non-carbide grades, including the SiAlON grades IS25 and IS35 for cutting high-temperature alloys and the CBN grade IB20H for hard part turning. At the same time, customer demand is not limited to the effective machining of exotics. Steel is still the main structural material and ISCAR’s last innovation was in the parting and grooving realm - two new PVD coated carbide grades, IC1010 and IC1030. These were utilised in inserts from the TANG-GRIP and DO-GRIP families (Fig. 2). The grades are intended for machining stainless steel and steel. While the hard submicron grade IC1010 is recommended for productive parting and grooving with high cutting speed, the tough IC1030 is more suitable for interrupted cut and unstable machining conditions. Upgrading grades is an essential component for tool manufacturers’ success, and innovations should have a strong foundation. This why ISCAR’s motto ‘to be on the upgrade’ guides and inspires new tool material developments.

To retain a position as a successful subcontract manufacturing business for more than 60 years is an achievement. But, to be an industry leader and innovator, like Pope & Meads, is something that has required significant investment. In the last three years, the company has invested in 8 new machine tools, all being optimised by cutting tools from ISCAR. The Hertford Company manufactures very high-quality components and assemblies for the aerospace, defence, medical, automotive and scientific instrument industries. Differentiating its quality and precision from other subcontract companies, 50 employee Pope & Meads has an ISO Class 7 Clean Room as well as ISO: 9-20001 S-C: twenty-one and are working towards their AS: 9100 accreditation. So, when the company invested in a Star S-R-32-J sliding head, Mazak 250-Q-S-M and three-hundred-M-Y turning centres plus two 4-axis Mazak V-C-N 430 A machining centres and three Hurco V-M-10s and a V-M-20 machining centre, in less than three years, it needed to ensure its cutting tools were capable of maximising the output on its new investments. Commenting upon this, Pope & Meads Director, David Williams says: “A few years ago, we set-up an engineering team with the specific remit of bringing a completely fresh approach to our facility to reduce waste, enhance quality and improve production methods. This team has been instrumental in our improvements in efficiency and productivity, we had to change machining strategies – closely looking at how to reduce set-ups through workholding and tooling strategies to improve our throughput and quality.” “We had been using ISCAR tooling for more than 6-years through a third-party supplier, but the supply chain was lacking the technical expertise to really deliver the changes we needed. As a long-term user of ISCAR products, we knew the quality and diversity of the product ranges was beyond reproach, but it was the technical support we really needed to reap all the benefits of the cutting tools. So, two years ago we went direct to ISCAR and we haven’t looked back since.” By working directly with Birmingham based ISCAR, Pope & Meads had gained a ‘technical partner’ that invited the subcontractor to regular technical seminars to grasp an understanding of the latest innovations. Supporting the seminars, ISCAR provided comprehensive training and support that importantly for Pope & Meads, included a complete review of machining strategies. Recalling one of the first projects that ISCAR were involved with, David Williams says: “One of the first jobs ISCAR engineers were involved in, was a magnetically sensitive component for a high-precision electron microscope. The large Swedish Iron billet is a regular job with a quantity of three-hunred-off per year and the ISCAR team initiated a change of tools that instantly reduced the roughing cycles from 3 hours to less than one.” The microscope part required a tapered bore with an outer bore diameter of 200mm tapering at 30 degrees to an internal bore seat diameter of 46mm with a depth of 146mm. The previous process required drilling and subsequent time consuming internal boring operations with depths of cut minimised to avoid disrupting the magnetic properties of the sensitive parts. However, the ISCAR application team demonstrated their ingenuity by researching the magnetic properties of Swedish Iron and this enabled them to completely change the cutting parameters of the drilling process. The 40mm indexable drill with ISCAR’s I-C-908 grade inserts was introduced with a massively increased feed rate. Increasing the feed rates from 0.028 mm/rev to 0.1 mm/rev, the Mazak 250-Q-S-M turning centre increased the turret feed from 28 to 95 mpm. This subsequently increased the Material Removal Rate from 35 cm3/min to over 120 cm3/min The result was a cycle time reduction from 353 seconds per hole to 103 seconds – an entire four minutes per part. Whilst this performance was undoubtedly impressive, it was a 15-percent insert cost reduction that was amplified by the fact that the new ISCAR I-C-nine-zero-eight inserts had 4-edges. This was compared to the previous competitor product with 2-edges, and that further impressed from a financial standpoint. Despite the combination of reduced cycle times, reduced tooling costs and economy being impressive; when combined with the increase in tool life – that was when the benefits became genuinely staggering. The ISCAR drill outperformed its competitor by extending tool life from 15 to 25 parts per insert edge. So, the ISCAR drill not only reduced cycle times by 4 minutes per part, it also reduced the cost per part by £3.75, a 70-percent saving. However, the drill was only the first step to producing the internal bore. Following the drilling operation, ISCAR introduced its ISO-Turn A-thirty-two-S boring bar with a CNMX insert geometry with ISCAR’s I-C-six-zero-fifteen grade. Tasked with internally turning the 30 degree bore, the ISCAR application engineers increased the cutting speed from 130 to 160 mpm and the spindle speed from 460 to 560 RPM compared to the previous tool. Increasing the Depth of Cut from 2mm to 2.42mm, the Material Removal Rate increased from 79 cm3/min to 120 cm3/min – once again outperforming the previous supplier. To emphasise the benefits of the ISCAR boring line, for a batch of 26 parts the tooling cost was 10% lower, the cycle time was reduced by 39 hours from 123 to 84 and the cost reduction per batch equated to a saving of £1,940! The combination of the ISCAR drill and C-N-M-X boring line is reducing machining times by 16 minutes per part, purely on the cone-shaped bore. Reducing machining times and set-ups is a critical factor for Pope & Meads, as the company often works to part tolerances of plus-or-minus 3-microns with completed assemblies often having a plus-or-minus 5-micron tolerance. Discussing the types of work undertaken at Pope & Meads and the emphasis on capacity, David Williams says: “Manufacturing high-precision parts and assemblies from nickel-iron, titanium, In-connell seven-one-eight and other challenging materials for aerospace and scientific projects, really isn’t the type of work you can subcontract out to external vendors. Added to this, we are on 24/7 call-out for some of our customers, so sufficient capacity is critical to our success. Along with the new machine tool investments, ISCAR has been instrumental in ensuring we can meet these capacity demands.” The Benefits of a close relationship “By developing a good working relationship with ISCAR, our engineering team is now looking to adopt ceramic tooling products for the first time. During early trials, the new ISCAR ceramic turning lines are capable of increasing our machining speeds from 38mm/min to over 115mm/min when roughing in-connell 718. This really is a ‘step-change’ in our machining strategies, something we wouldn’t have considered without the expert advice of ISCAR engineers. We are still in the infancy with trails, but the results have been outstanding.” Currently undergoing a trial phase on a scanning component for the semi-conductor industry, Pope & Meads is tasked with machining 336 parts per year, with volumes expected to rise to over 500 in subsequent years. By changing out the existing ISCAR CMNG 12047 TF IC-806 insert grade and replacing it with the ISCAR ISO-TURN RNGN 120700-T I-S-350 the performance improvements have initially been staggering. ISCAR has increased the cutting speed from 191 to 573 R-P-M with a feed rate increase from 38 to 114.9 millimetres-per-minute. This has reduced the machining time from 26 minutes to just over 8 minutes. Furthermore, the double-sided ceramic insert grade is destined to reduce tooling costs whilst improving productivity rates. ISCAR’s Area Sales Manager, Mr Dave Thompsell says: “Ceramic tooling requires a step-change in machining strategies and customers need to adopt completely new philosophies. For example, Inconel seven-one-eight is generally machined with C-N-M-G insert grades at 40-50 meters-per-minute, we are applying ceramic button inserts at over 180 meters-per-minute with a feed rate of 0.25 millimetres-per-revolution. It is these parameters that are creating the huge benefits for Pope & Meads.” “As part of the machining strategy, we initially hit the part with a C-N-M-G insert to create an entry angle of 35 to 45 degrees. This is because ceramic tooling is sensitive to impact and intermittent cutting. We then radially enter the part with the ceramic button tool and during the cycle, we continually vary the depth of cut to prevent notching. By introducing these strategies, we are witnessing huge productivity gains and we are excited about introducing additional new lines to this part, and many others at Pope & Meads. Despite being a company that is over 60 years old, the refreshing approach to machining strategies and cutting tools will allow ISCAR to deliver significant benefits to this great company,”
No Setup, No Downtime for Smart Factories. Manufacturing is on the eve of comprehensive digitisation that will impact product design, process planning, machining, assembly and more. The driving force behind the changes is a series of technological breakthroughs related to the fourth industrial revolution, Industry 4.0. With the use of network communication, new digital technologies combine physical manufacturing systems with virtual worlds of knowledge and 3D modelling. The target is significantly increased output, but as manufacturing systems improve their intellectual features, they become more complicated and expensive. Minimizing downtime of such systems is a ‘must’ for the development of every system component such as machine tools, workholding devices and cutting tools. Cutting tools can not only cut metal but also cut downtime, depending on their design concept. Cutting tools with exchangeable cutting heads from cemented carbides are very common in metalworking today. Advances in tool grinding and resharpening machines have simplified production of solid carbide tools and their regrinding. This in turn has resulted in an increased number of medium and small tool manufacturers and regrinding services. It might have been expected that the solid carbide design approach would seriously challenge the exchangeable alternative and quickly regain lost ground. However, this hasn't happened. In fact, the situation has reversed: progress in machine tool engineering and the current trend towards smart manufacturing hold good promise for the future of assembled cutting tools. An example can be provided by taking a look at ISCAR. It introduced the ‘no setup’ principle with exchangeable heads, whereby replacing a worn head would not require additional tool setup or adjustment. The ‘no setup’ principle was successfully realised in ISCAR’s MULTI-MASTER and SUMOCHAM rotating tool families. In non-rotating products, the new MULTI-F-GRIP and LOGIQ-5-GRIP parting and grooving tool families represent the fruits of a different approach where the assembled tool comprises a tool block and an indexable multi-pocket adapter carrying replaceable inserts. The high precision of the assembly components eliminates additional setups from pocket indexing. Along with the benefits in reducing downtime, these tools feature exceptional versatility. The MULTI-MASTER head can be mounted in different tool bodies to enable thousands of tool combinations for a broad range of applications. The MULTI-F-GRIP family integrates both TANG- and DO-GRIP inserts. Not so long ago, versatility was considered the main advantage of tools with exchangeable heads. But recent progress in machine tool building and, especially, the trend towards smart manufacturing based on Industry 4.0 concepts, returned ‘no setup’ capabilities to the fore. A further advantage of using tools with exchangeable heads is their ability to customise tool configurations according to the requirements of a specific part. Multi-tasking machines that enable various types of cutting in one single-step process have become very popular. These machines have driven-tool capabilities for combining machining by rotating and no-rotating tools, which can significantly improve productivity. In addition, machine tool builders offer a range of options to supplement a standard CNC lathe with driven-tool functions, and so transform the lathe to a multi-tasking machine. The MULTI-MASTER line features a wide variety of tool bodies with different adaptations, reducers and extensions that can minimise tool overhang. This greatly contributes to reducing bending load on the driven tool unit mechanism to improve performance and tool life. Implementing Industry 4.0 concepts into the metalworking industry is exemplified by the integration of the ‘no setup’ principle in assembled tools with exchangeable heads. And it is not only about saving cemented carbide; the new developments have generated important capabilities to maximize machining output and decrease production costs.
ISCAR Imparts Turning Wisdom at Seminar Last month ISCAR hosted its Machining Techniques Customer Seminar. The two-day programme welcomed more than 320 customers . MTD magazine visited the action-packed event to look at the latest innovations. Following-on from the successful event that the cutting tool manufacturer hosted in June, the comprehensive Autumn programme was packed with cutting tool demonstrations that were transmitted live from the technical centre to the seminar theatre. The demonstrations covered all core disciplines with H-S-M strategies, continuous and intermittent parting, drilling, turning, titanium milling and much more. Each of the 30-minute demonstrations were highlighted in a seminar booklet that provided attendees with the cutting data, material grade and performance characteristics of each tool. The demonstrations included shouldering and slotting with the 16mm diameter MULTI-MASTER solid carbide milling range. There were numerous examples of the indexable MULTI-MASTER line that included grooving, scanning, corner rounding, pocketing and chamfering – all followed by the SOLIDMILL premium line conducting trochoidal strategies. Other highlights from the milling stable included the MILL4FEED, LOGIQ4FEED, MICRO3FEED and SOLIDFEEDMILL, which were conducting high-feed roughing, rest machining, pocketing and finishing. The turning line provided impressive demonstrations from the LOGIQ4TURN, SLIMGRIP, ISOTURN, SUMOCHAM. Also present was the brand new MULTIFGRIP blade holding tool bodies and the TANGFGRIP high-feed parting-off blades that MTD magazine covered in the September issue. We spoke to ISCAR Tools, Andy Hayward who talked us through the benefits of the new parting line. The continuous parting demonstration undertaken on the company’s Ma-zak Quickturn Smart 350 at the event was dry parting a 50mm diameter bar of EN19 at 0.25mm/rev, 0.35mm/rev and 0.5mm/rev. Andy Hayward says: “We have found that you cannot increase the rigidity of parting systems by making the tool wider, as the insert width restricts the tool holder support in the groove. You can only improve them from making them deeper and this is what we have done with the new MULTIGRIP and TANGGRIP system. Standard parting tools run at a feed rate of 0.15mm/rev to 0.2mm/rev on EN19, the MULTIFGRIP tool holder supports the new square block TANGFGRIP blades to minimise vibration and deflection, so cutting feeds can be more than doubled through the new deeper design." To emphasise this rigidity, the second demo at ISCAR was undertaken on 120mm diameter bar with 60mm tool overhang. This second demonstration running with 20bar coolant pressure through the ISCAR JETCUT high-pressure coolant system was initially run at 0.25mm per-revolution, then 0.35mm per-revolution and finally 0.45mm per-revolution. With competitor parting systems typically running at 0.15 to 0.18mm per-revolution, the vibration dampening characteristics of the TANG-F-GRIP and 4-insert MULTI-F-GRIP blade are easily achieving feed rates at between double and even treble that of alternate systems. Pushing the benefits of the rigidity across to attendees, ISCAR ran the same 50mm and 120mm diameter demonstrations under interrupted cutting conditions. Applying its new IC808 insert grade that is a general grade for steel, stainless and exotics, the performance characteristics were impressive, running at 0.25, 0.35 and 0.5mm/rev. Discussing the performance of the MULTIGRIP, Andy Hayward says: “When running the new parting system at 0.2mm/rev on intermittent cuts, it makes a nice dull sound that highlights how the forces are being absorbed through the tool and into the machine.” “We have run tests with the new MULTIGRIP on SAE 4140 steel at a speed of 150 meters/min at a feed rate of 0.4mm/rev with a 60mm tool overhang. Using the old ISCAR parting system with the TGSU353IQ blade, the blade would deflect by 0.325mm when intermittent machining at these parameters. The new MULTIGRIP deflects by less than 0.169mm, that is a 60% reduction on the previous system. That is a huge difference and the visitors to our Machining Techniques Customer Seminar were clearly impressed by the huge leap forward ISCAR has taken with this new system.”

As an essential aspect of the turning process, parting and grooving is one facet of the machining process that faces a constant challenge to integrate ever improved efficiency and downtime reduction methods. To generate productivity and efficiency gains in this arena, ISCAR has now introduced a new system for parting and grooving operations. Appreciating the importance of parting and grooving operations in the turning process, ISCAR has responded to the complex industry needs by developing a comprehensive range of highly effective parting and grooving solutions. The new line-up includes an extensive choice of insert geometries, chip breakers and carbide grades with a range that is continually expanding. The development of Industry 4.0 has seen ISCAR introduce new parting and grooving technologies capable of integrating seamlessly with the new wave of machine tools that work at high feeds. The TANG-F-GRIP has been designed to meet these needs and lower costs whilst achieving higher productivity levels. The TANG-F-GRIP comprises a robust tool block carrying square blades that feature four pockets. The new parting concept is capable of parting-off up to 120mm bar diameter. The TANG-F-GRIP is easy to mount and operate on all machine types, including multi-task machines on the X-AXIS without any need for special adjustment. It enables the mounting of both TANG-F-GRIP and DO-GRIP blades on the same blocks. The square blade design possesses a support system that ensures vibration-free grooving and parting. TANG-F-GRIP also saves on setup times in cases of pocket damage as the block’s configuration allows a blade to be rotated to a new pocket without setup. The TANG-F-GRIP is intended for high feed parting and it extends insert life, improves surface finish and part-off straightness, especially when parting large diameters. The new patented blades reduce cutting time and enable significant material savings. For example, a 120mm bar can be cut with a HF (high feed) 3mm blade at a feed rate of up to 0.4 mm/rev. The HF tangential single-ended insert was developed to enable highly efficient parting at very high feed rates by use of new chipformer technology. The insert features a new insert chipformer to allow unobstructed chip flow, which increases insert and blade tool life and leads to very high productivity gains. All TANG-GRIP inserts can be integrated into the TANG-F-GRIP system that is also compatible with DO-GRIP DGN double-sided twisted geometry parting inserts. This provides an extensive choice of parting widths for all application ranges. Incorporating a revolutionary secure clamping method that uses a tangentially orientated pocket, this facilitates pocket life that is three times longer than other conventional self-grip systems. The robust clamping method enables machining at high feed rates and provides excellent straightness and surface finish characteristics while the flat top configuration prevents chip obstructions under numerous machining conditions. The JETCUT incorporates through coolant channels to deliver coolant close to the cutting edge, which improves chip formation and reduces flank and crater rates. When machining materials such as stainless steel or high-temperature alloys, the temperature near the cutting edge area becomes extremely high. In addition, these material types tend to generate built-up edges. These problems can be moderated by targeting high-pressure coolant directly to the cutting zone. ISCAR maintains its unrelenting progress and this desire to provide customers with the very latest, most efficient metal cutting technology is reflected in the introduction of TANG-F-GRIP solutions.
The automotive industry is renowned for demanding ever faster turnaround times and tighter tolerances. To meet such demands, Clacton-on-Sea subcontractor Tridan Engineering has made EDGECAM a major part of its manufacturing processes. EDGECAM programs a total of 16 Mazak CNC machines, of which six are 5-axis, including a Variaxis i-500 with a Palletech automation system. It is with the 5-axis work that EDGECAM is proving particularly valuable. One of the biggest challenges facing their production process is keeping up with ever-changing tooling. Commenting upon this, Tridan Engineering’s Machine Shop Manager, Mr Paul Coupland says: “We manufacture a range of automotive components, mainly for Ricardo, along with some F1 test parts. We work with two main tooling suppliers, ITC and ISCAR, they are both improving their tools all the time. EDGECAM provides us with the optimum machining strategies every time the cutting tool is updated. For example, we produce a number of gearbox transmission systems for Ricardo, and some diff cases for world rally cars. We’re currently working on a rear differential case for an off-road race car.” “EDGECAM programs all our machines to their absolute top tolerances – we regularly have a 2-micron tolerance on most of our jobs, and we can guarantee that they’re manufactured to that required high precision every time.” The CAM software’s powerful Waveform Roughing Strategy has been a major influence on the Essex Company and how they machine their automotive components. Everything is now done with the Waveform trochoidal milling and tooling strategies to take full flute length cuts and optimise tooling performance. Lead Production Engineer Mark Proctor says they’ve had some spectacular results with it, but admitted they were at first nervous about the prospect of ramping up feeds and speeds and using the full flute length. “When we were told we could machine a piece of S143 stainless steel at eight metre a minute, we thought the cutting tool wouldn’t last two seconds.” But he says once they saw the resulting faster cycle times, and that the tool was safe from damage, they made the decision to do all their Waveform roughing at the machine’s fastest feed rate. “For instance, we needed a finished component that’s only 20mm thick, coming from a six-inch S143 round billet. That means there’s an awful lot of metal to cut away. For that job we used a 12mm cutter for a 24mm depth of cut at a feed rate of just under nine metres a second, and the job ran for ten hours before the cutting tool needed replacing.” Tridan ships around 9,000 parts a month to customers around the world – anything from small components to workpieces up to 1.6 metres, both as single units and in large batches. Almost every automotive part they produce goes through EDGECAM. “When we get the model from the customer, normally as a STEP file, we load it into EDGECAM, select the stock, devise the machining strategy, add the tools and toolpaths, and run the program through the simulator. When it comes through that, we use the NC editor to post the program out to the machine via a DNC wireless link, and explain the job to the operator. He then goes to the shopfloor with a setup sheet that shows which tools he needs, and runs the machine.” Mark Proctor says EDGECAM is even better since it included a button to unhide the stock underneath. “In earlier releases it wouldn’t see the stock underneath, but it’s now an even better cycle with this option.” Describing 5-axis machining and automation as the way forward for Tridan Engineering, Paul Coupland says their recent acquisition of the Mazak Variaxis with a Palletech automation system adopts both of those aspects. “5-axis is definitely the future for us, as it enables us to machine much faster than 3-axis can, through the ‘Done In One’ capability, without the need for additional set-ups. And the automation system on the Variaxis can manage six pallets, which is perfect for our needs. We can add six pallets at any stage of the operation to keep it going. It also means we can carry out lights out machining. Depending on the job, it can run constantly for between eight and 14 hours without any manual intervention.” Currently operating from 26,000 square foot premises with 66 employees, growing order books mean the company, which was founded in 1968 and now owned by the Langham Group, are now looking to take what he describes as their next natural step. “We’ve recently bought a third of an acre next door, and are planning to double the size of our machine shop.”
