An Industry In High Demand

An Industry in High Demand

Tom Nathan of ANCA explains how demand for carbon fibre reinforced plastics (CFRP) growing at 9.3 percent per year leads to huge potential for cutting tool manufacturers. 

Using strengthening fibres embedded in a supporting material has been around since the dawn of time. From mud brick houses reinforced with straw to the first composite bows made with wood, bone and pine resin, it was recognised that composites deliver superior compressive and tensile properties. 

The transportation, low-carbon energy generation, aerospace, defence, civil construction and sporting goods industries have all adopted composites for their high-performance and low weight applications—and the demand continues to grow year-on-year. A report by Credence Research in 2019 estimates a Compound Annual Growth Rate (CAGR) of 9.3% for Carbon Fibre Reinforced Plastics (CFRP) during the period 2017-2025. Growth in the poly-crystalline diamond (PCD) tool market has been double that of standard carbide cutting tools over recent years, making it an outstanding opportunity for tool manufacturers looking to be active at the leading edge of cutting tool technology. 

Tom Nathan, product manager at ANCA, has witnessed the huge increase in inquiries in this area – reflecting a growing demand by tool manufacturers to produce cutting tools to service this market. “Commercial applications for composite materials continues to grow year-on-year with the market space for cutting tools also expanding. With superior strength to weight ratios, CFRP is being used in a wide variety of low weight structural applications from planes, cars, turbines and even drones,” he says.

Cutting tool manufacturers are creating and adopting a variety of cutting tool designs and technologies—developing new tooling for the wide variety of composites used today. ANCA has been working closely with its customers to design innovative solutions that help address these needs, creating new tool geometries and machine technologies that can erode and grind market-leading CFRP solutions.

Understanding the Composite Market

Industries today use a variety of composite-matrix materials (epoxies, phenolics, polyimides) and fibres (carbon, Kevlar, glass) to suit varying applications with very different material properties. In metal cutting, the creation and evacuation of chips serve to remove heat from the point of cutting. In a polymer matrix composite, the matrix tends to be soft but very tough. When analysed at the micro level, machining of polymer matrices does not form chips, but rather a fine ‘dust’ that results from localised micro-fracturing. This matrix dust does not readily dissipate heat from the cutting edge as the matrix material generally has a very low thermal conductivity. 

Nathan states that this creates significant problems when using ferrous (iron) based cutting tools for machining composites. “The increased heat leads to localised thermal expansion and lower yield strength which varies the tool geometry, ultimately leading to premature wear,” he says.

The next challenge comes from the embedded fibres. These fibres are strong, stiff and highly abrasive when machined. Different composite materials utilise different fibre orientation methods to aid the mechanical properties sought. Fibre forms can be unidirectional, fabric weaves, braided or even chopped which makes the composite materials behave very differently when being machined.

To complicate matters more, Carbon Fibre Reinforced Plastics (CFRP) can be layered with backing materials comprised of aluminium or titanium to aid strength and rigidity. Alone, these substrates require their own types of tooling geometries, however, varying layers of these materials with matrix composites materials demands tool geometries that can cater for a wide variety of machining operations with dramatically different cutting properties.

LVD Launches New Large-Format Laser Cutting Machine

LVD Launches New Large-Format Laser Cutting Machine

LVD launches Taurus FL, a new large-format gantry-style fiber laser cutting machine engineered for extra-large sheet metal cutting capacity. A unique modular design, the machine size begins at a 12-meter bed length and can be expanded in increments of 2 meters to a maximum bed length of 40 meters to suit user needs. The large format allows a diverse range of parts to be cut and efficiently nested, increasing productivity and optimising material usage.

LARGE-SCALE ADVANTAGES

Taurus FL delivers the flexibility to process extra-large sheets or multiple sheets, cut a range ensure high machine dynamics of jobs in varying batch sizes, shapes and material types accommodating workpieces up to 3.3 meters wide and up to 30 mm thick.

Large parts can be processed without repositioning while multiple smaller workpieces can be positioned on the cutting table and processed in continuous fashion, without interruption. Parts can be cut on one section of the table, while loaded/offloaded on another, keeping downtime to an absolute minimum.

Taurus FL is designed for easy access. Only the gantry features an enclosure, not the complete machine. The mechanical design and drive system ensure high machine dynamics in large-format cutting.

The operator has use of two touch panels for convenient access to the control at all times.

A handheld control unit enables the operator to safely move all axes in manual mode for machine setup or to load the nozzle changer. A camera located inside the cutting zone and a monitor on the operator console allow continuous monitoring of the cutting process. The cutting zone has a detachable front panel, providing access for maintenance.

No special foundation is required for the machine.

EXPANDED MACHINE SCOPE

Taurus FL also provides the option of beveling cutting or 2.5D cutting up to 45°. The fiber laser is an ideal tool for reliably producing high-quality bevel cuts in a large-format cutting platform. The bevel cutting option offers a fast and cost-effective way to prepare material for subsequent welding operations or to create geometrical shapes.

The Taurus FL bevel head uses two direct-drive motors. The direct-drive principle uses no transmission components resulting in the highest possible accuracy and a fast responding system. As a result, consistently precise bevel cutting is assured.

The bevel head is able to cut on a horizontal surface as well as cut shapes in pre-formed parts or cut under angle within the limits of the Z-axis and +/- 45 deg.

An optional automatic nozzle changer increases machine uptime and throughput. The unit has storage for 30 nozzles in a turret-style holder positioned close to the cutting head. The nozzle changer features an integrated camera that checks nozzle alignment, size and condition. It offers automatic calibration of the capacitive height sensing and nozzle cleaning after a preset number of piercings.

Horn Expands Gear Cutting Portfolio

Horn Expands Gear Cutting Portfolio

Paul Horn GmbH is expanding its range of gear cutting products. Horn’s new tool system for milling bevel gear teeth allows the complete machining of bevel gears on universal turn-mill centres. The system was created in cooperation with machine manufacturer INDEX and means that users no longer need any special machines to manufacture gears of this kind. It also allows all functional surfaces to be produced together with the gear teeth in one clamping. This enables high component precision, short lead-times, a very cost-efficient process and short machining times as a result of controlled machining cycles.

With a universal turn-mill centre from INDEX, components with bevel gear teeth can be efficiently and flexibly manufactured, including in small quantities. This also makes the process attractive to small and medium-sized companies that would previously have bought in gears or had them manufactured externally.

For the process, Horn relies on its S276 and S279 double-edged indexable inserts, which are screwed on tangentially. This makes it possible to achieve a stable insert seat, which is particularly important during form milling. The tool does not have to be remeasured after the inserts have been turned around or changed because the inserts are precision-ground on the circumference.

The milling body can be equipped to allow for different numbers of teeth and outer diameters when cutting gears. The process of developing the complete system (cycle, tool and clamping) called for a great deal of expertise on the part of both the machine manufacturer and the tool manufacturer. To implement the process, various types of INDEX machine with a “bevel gear hobbing” cycle are required. Horn offers the milling cutter bodies with the HSK-T40 and HSK-T63 interfaces. The profiles of the inserts are module-dependent and precision-ground.

Protective Films: A Powerful Technology Supporting Laser Cutting

Protective Films: A Powerful Technology Supporting Laser Cutting

Adapted protective films are essential for the productivity of laser cutting machines. In this article, Abdelrazak Kerbal of Novacel explains why.

Since the beginning of laser cutting technology, the metal sheets preserved by a protective film faced difficulties while being cut. With the latest generation of machines with fiber laser technology, the cutting process was even more complicated. Indeed, because of their wavelength, fiber laser machines could not safely cut the sheets laminated with a standard protective film. 

To overcome this difficulty, manufacturers had to burn or to remove  the protective films covering the sheets before proceeding with cutting. This practice tends to increase both the production time due to this double cutting pass and the wastage of material due to the sparkles or tools marks.

In addition, the thermal effects of cutting with the flow of assist gas could hinder the smooth running of the process. Indeed, during laser cutting, the film undergoes the heating on the affected zone and tends to soften. This phenomenon, coupled with the diffusion of the high-pressurized cutting gas, can generate bubbles. These bubbles represent areas where the film is no longer sticking to the sheet and are therefore points of weakness in the protection.

Sometimes, dark marks may appear around the cut edges because of the carbon black from the black/white films burnt. In some cases, users must remove non-performing protective films in order to be able to work properly with their machine. 

To overcome all these problems and to guarantee a surface protection without interfering with the smooth running of the process, Novacel has been offering protective films specifically designed for laser cutting for over 20 years now. 

In fact, Novacel’s range of protective films for laser cutting are developed in partnership with the leading laser cutting machines manufacturers and compatible with all the laser technologies currently used for cutting metals. As the main customers of the company are large metallurgy groups, Novacel products are also widely used by the big names in household appliances, construction and decoration materials, and furniture, which have to present surfaces to the final consumer free from any imperfections, scratches or soiling.  

Appropriate Protective Film to Enhance Efficiency and Quality in Laser Cutting

Adapted protective films are essential for the productivity of laser cutting machines. The choice of a protective film depends upon the laser cutting technology used, the protected materials, the sub processes and the industrial segments of application. Thickness of the film, adhesive material used and adhesion level are key parameters for successfully selecting an adapted protective film.

Key Considerations When Choosing An Industrial Cutting System

Key Considerations When Choosing An Industrial Cutting System

Aaron Zou, regional director for Asia at Hypertherm, discusses the trends shaping the metal cutting industry, the common industrial cutting challenges, and key considerations in choosing your metal cutting systems.

Aaron Zou, Regional Director for Asia, Hypertherm

Founded in 1968 and headquartered in New Hampshire, United States, Hypertherm designs and manufactures industrial cutting products for use in a variety of industries such as shipbuilding, manufacturing, and automotive repair. Its product line includes cutting systems, in addition to CNC motion and height controls, CAM nesting software, robotic software and consumables.

In an interview, Aaron Zou, regional director for Asia at Hypertherm, discusses the trends shaping the metal cutting industry and the common industrial cutting challenges. He also talked about the latest plasma technologies to address those issues as well as the key considerations in choosing metal cutting systems.

WHAT ARE THE TOP TRENDS CURRENTLY SHAPING INDUSTRIAL CUTTING PRACTICES IN THE METALWORKING INDUSTRY?

Aaron Zou (AZ): The current landscape brought about by the COVID-19 pandemic has accelerated the transformation of traditional manufacturing practices—forcing manufacturers to leverage on innovations, integrate new technologies to current processes, and to develop new solutions or services to address evolving market needs. This change will continue to be driven by automation and digitalization, where technologies related to the Industrial Internet of Things (IIoT) will enable companies to build up smarter production facilities and allow the industry to establish a smart machinery eco-system. By adopting such technologies, businesses can better utilize the ‘down time’ during this pandemic to improve production efficiencies and to implement automated processes, so as to be prepared as normalcy returns and pent-up demand starts picking up.

WHAT ARE SOME COMMON INDUSTRIAL CUTTING CHALLENGES?

AZ: Most manufacturers in the metalworking industry are familiar with increasing customer demands for improvements to their parts design, in a bid to achieve higher quality standards. In fact, many have had to deploy a secondary operation, like drilling or grinding, to correct unsatisfactory hole quality after using a plasma system on a CNC machine.

Another challenge that manufacturers typically experience is related to bevel profiling—an increasingly difficult job due to advanced automation in welding processes. A common approach is for manufacturers to have their parts cut by plasma systems and later achieve the bevelled edges using secondary processes like grinding, mechanical bevel, or oxyfuel. In some cases, manufacturers were able to achieve bevelling using just their plasma CNC machines. However, this usually involves some constraints such as machine bevel set-up (which can take up to 3 hours) and bevel profile outcomes that do not meet the required design tolerance.

Furthermore, manufacturers have to deal with rising expectations and demand for better customer experience. Product quality is increasingly becoming a given, or a ‘standard’ feature, and customers’ expectations are shifting—valuing the experience delivered over the entire duration of their project life cycle more than they had previously. Businesses will need to redirect their focus from merely selling products and services to creating an exceptional overall customer experience.

HOW DO THE LATEST TECHNOLOGIES DEVELOPED BY HYPERTHERM HELP BUSINESSES OVERCOME THE SAID CHALLENGES?

AZ: Through the expertise of our team and the feedback collected from our users, we were able to develop a range of specific applications to enhance plasma machine usage with Hypertherm’s automated solutions. SureCut technologies like True Hole and True Bevel were developed to remove the need for secondary operations like grinding to produce high quality parts, and to improve production efficiency by reducing set-up time or the need for trial-and-error.

Barrel Cutter Shapes A New Milling Trend

Barrel Cutter Shapes a New Milling Trend

Advanced workpiece manufacturing technologies—such as metal injection moulding, 3D printing, investment casting and close-tolerance forging—innovative machine tools, and a quantum leap in digitizing of manufacturing will increase the needs for finishing complex surfaces with minimum machining stock. Article by Andrei Petrilin, ISCAR.

Endmills featuring a cutting edge that is actually the segment of a large-diameter arc were introduced approximately 25 years ago. As the cutting-edge shape of these endmills is reminiscent of a barrel profile, terms such as ‘barrel milling cutters’, ‘barrel endmills’ or, in shop talk, often simply ‘barrels’ soon became common when referring to these types of endmills.

At first, the use of these barrel-shape mills was limited more or less to a few specific applications, such as machining 3D surfaces of complex dies and turbomachinery components. However, advances in 5-axis machining and in CAM systems have significantly expanded the boundaries of barrel endmill applications.

At the same time, the design principle of a cutting edge as the segment of a large-diameter arc has been realized successfully in other types of milling cutter—the tools for high feed milling (HFM), also referred to as ‘fast feed’ (FF) milling. The concept provides a toroidal cutting geometry that ensures productive rough machining at extremely high feed rates due to a chip thinning effect. Unlike high feed milling tools, barrel endmills are intended not for roughing but for finish and semi-finish machining of 3D surfaces with low stock removal.

Traditionally, ball-nose and toroidal cutters perform these machining operations. However, the large-diameter arc of the endmill cutting edge results in a substantial reduction of the cusp height generated between passes machined by a ball-nose or toroidal cutter. Another advantage of this type of cutting edge versus ball-nose and toroidal cutters is a significant increase in the distance between passes (a stepover or a stepdown, depending on the direction of a cutter displacement after every pass)—at least five times more without degradation of the surface finish parameters! (Figure 1) This means that the number of passes and, subsequently, machining time can be noticeably reduced. Increasing the distance between passes also improves tool life and, therefore, diminishes tool cost per part.

The classical barrel shape in endmills has undergone some changes to make these cutters more versatile. Combining a ball-nose tip with peripheral large-arc cutting edges creates a multi-purpose ‘cutting oval,’ which facilitates the use of a barrel endmill as a ball-nose milling tool.

Fagor Arrasate Participates In The Development Of Smart Shears For HSS

Fagor Arrasate Participates In The Development Of Smart Shears For HSS

Fagor Arrasate, specialist in the design of forming and cutting lines, takes part in a European investigation project to design smart shears for high-strength steel (HSS) with a predictive system which warns about cutting tool deterioration.

The project, called IntellCutProcess, will analyse the various parameters that are involved during the cutting process, such as cutting strength, the die looseness or separation, or the cutting angle. The data obtained will allow for the optimisation of the cutting tool regarding aspects such as the material used and the protective coating.

The shear will be equipped with sensors which will measure the different cutting quality indicators, such as the burr height and the cutting area profile. With this information, the system will be able to monitor the cutting tool’s degradation state, so as to uphold the highest quality and cutting precision. In addition, the predictive system will make it possible to plan the required interventions with scheduled production downtimes, which increases the OEE (Overall Equipment Effectiveness.)

In order to validate the results of the research, a fully sensorised shear prototype for the cutting of heavy thickness metal sheet will be built first. Afterwards, the new equipment will be installed in an actual operational cutting line.

An All-rounder In Metal Cutting

An All-rounder In Metal Cutting

Here’s how a 5-axis universal machine revolutionised the production processes at Polar-Form Werkzeugbau GmbH. Article by GROB.

G550 5-Axis universal machining centre at POLAR-FORM Werkzeugbau GmbH.

Permanent bottlenecks in the milling area and high time and cost pressures in production have, over the years, convinced POLAR-FORM Werkzeugbau GmbH to purchase a 5-axis universal machining centre with automation. An internal technical committee with all decision-makers and machine operators determined what the new machine was capable of or, better still, what existing problems it had to solve. This included issues such as deep hole drilling, milling, high payload weight, large additional tool magazine, large working memory, enormous data volume, limited space, pronounced reliability, and perfect automation.

After intensive market research, three machines were finally selected. The final decision was made in favour of a 5-axis universal machine from GROB, which is equipped with a circular pallet storage system and additional tool magazine.

“We never had any doubts about our decision, but what this machine can really do only gradually became clear to us,” says Polar-Form Production Manager Dietmar Klötzle.

Optimal Configuration – Perfect Training

The detailed work began once it was certain that a machine from GROB would be purchased. Despite the limited space available, the GROB layouts and installation plans enabled the perfect location to be found quickly. 

The training of the employees took place on-site at POLAR-FORM. Even in the initial phase, the trainees practiced on a range of parts that are actually produced at POLAR-FORM.

“The idea behind this was to have the machine demonstrated on POLAR-FORM parts and not just on any sample parts,” says Klötzle. Since the programming of the machine was also carried out on-site using a CAM program, all the employees concerned could be called in and thus were trained from the very beginning. This way, all of the basic settings were quickly covered via testing and the horizontal spindle concept of the new GROB machine could be illustrated very clearly.

Machine programming was also very simple, since it was possible to load the programs much more elegantly than before via the programming station, and this no longer had to be done directly at the machine. “It soon became apparent just how well the CAM system communicates with the G550 and Heidenhain control system,” recalls Michael Gür, team leader for rough cutting at POLAR-FORM. Now the cycles can be transferred one-to-one to the G550—a procedure that was not possible with the previous machines.
