One of the differentiation that high-performance tools have is the preparation of their cutting edge. Cutting edge preparation influences the Thermo-Mechanic aspects of the cutting process such as the deformation zone, the temperature distribution in the cutting process, the machining process, the chip formation and its flow, the superficial integrity of the job, resistance to wear and microchipping and tool life.

Cutting edge preparation is the process of adapting the surface of the cutting edge for improving the contact zone for machining and the coating process. The cutting-edge preparation could be done by either honing, chamfering or the combination of both to improve the microtopography for the efficient and effective cutting action.

When the process is executed properly it increases the strength of the cutting edge and lifetime of the tool, increases coating productivity minimizes the possibility of built-up-edge formation, and enhances the surface quality of the job.

AXIS mICRO Tools uses a unique proprietary superfinishing process to stabilize the cutting edges. The process is highly reliable, consistent, and repeatable. Application industries benefiting from this process are Aerospace, Medical, mICRO mACHINING, e Mobility, and Consumer Electronics, to name a few and the list is increasing.

Here is a case study which brings succinctly the benefits of superfinishing and edge preparation on the performance of AXIS Tools used in a high precision application in the Aerospace Industry.

 

Case Study
Machining of Engine Case
Cases are an integral part of the Aircraft Engine that shield and support the parts required for combustion. Hence, they are made from materials that can withstand rapid changes in temperature and are light weighted as well. Heat Resistant Super Alloys (HRSA) such as Inconel and Nickel Alloys, Titanium and Stainless Steels are the materials of choice in such applications.

Drilling Nickel based super alloy is very challenging due to the material properties, operating conditions – large amount of heat generation and its dissipation – and the high component quality requirements.

Here is a case of effective design, appropriate edge preparation, and superfinishing – to enhance coating productivity and chip evacuation ( heat dissipation ) – that has resulted in the outstanding performance of the drill.

Conclusion
Controlled and Consistent micro honing of the cutting edge with a satisfactory texture for subsequent coating process results in strengthening of the cutting edge for improved cutting action, better component quality, and extended tool life.

GF Machining Solutions’ wire-cutting EDM machines take micro machining to the extreme https://mfgtechupdate.com/gf-machining-solutions-wire-cutting-edm-machines-take-micro-machining-to-the-extreme/ Mon, 28 Mar 2016 10:14:36 +0000 http://mfgtechupdate.com/?p=8061 A new degree of precision to achieve extreme accuracies on machine positioning and pitch is now possible with GF Machining Solutions’ hallmark AgieCharmilles CUT 1000 X, CUT 1000 X OilTech, CUT 2000 X, CUT 2000 X OilTech and CUT 3000 X machines.

A new degree of precision to achieve extreme accuracies on machine positioning and pitch is now possible with GF Machining Solutions’ hallmark AgieCharmilles CUT 1000 X, CUT 1000 X OilTech, CUT 2000 X, CUT 2000 X OilTech and CUT 3000 X machines. To support their extraordinary precision, adapted mechanical structures for high accuracy, high standard thermal stability and dedicated machine calibration and testing are mandatory.

Today, the increased pressure on manufacturers across a variety of segments to produce always more complex and accurate components in large volumes makes the choice of machine absolutely critical in terms of precision and reliability. In the context of just-in-time production flows, rejected parts can have devastating effects on timing, costs and a manufacturer’s image. As those manufacturing demands become more extreme, GF Machining Solutions’ AgieCharmilles X series takes highly accurate wire-cutting EDM to a new extreme by eliminating pitch and positioning errors.

GF Machining Solutions’ specific and uncompromising calibration testing on the machines’ production site is similar to the demands manufacturers face daily. The CUT 1000 X and CUT 1000 X OilTech deliver pitch accuracy of ±1.0 μm over 200 mm by 140 mm, and M-shape form accuracy of ±1.0 μm. The CUT 2000 X, CUT 2000 X OilTech, and CUT 3000 X deliver pitch accuracy of ±1.5 μm over 340 mm by 240 mm (460 mm by 320 mm for CUT 3000 X size), and form accuracy of ±1.5 μm.

Best tolerances for positioning and geometrical controls

Expert geometrical and erosion inspections ensure the results that manufacturers’ customers expect. Prior to installation, GF Machining Solutions’ experts machine a large number of holes in a plate, then use a high-precision coordinate measuring machine (CMM) to measure the position of each hole’s center. The CMM results are then reloaded into the computer numerical control (CNC) of the X series machine. That correction of the CNC guarantees perfect pitch and positioning accuracy from the very first die or mold that the customer machines.

Thanks to that expertise in testing and calibration, manufacturers can confidently produce stamping tools and multi-cavity molds for electronics, information and communications technology, as well as the tiniest components for MedTech and watchmaking. Optimal machining conditions for extremely demanding micro applications are ensured by the X series machines’ high precision axes, short measurement loops, dual measurement system on all axes, consistent separation of the EDM area from heat sources, and the submerged working area.

Moreover, quality and accuracy are guaranteed during assembly of an X series machine, due to GF Machining Solutions’ thorough measurement and high process control standards for all assembled mechanical components.

Highest productivity

In addition, the X series machines offer manufacturers a wide range of productivity- and quality-enhancing features:

  • Exclusive Automatic Wire Changer (AWC) two-wire spool allows the use of larger diameter wire or premium wires for the main cut and then automatically switch to smaller wire for the finishing cut resulting in huge increases in cutting speeds. Productivity is boosted by fast and reliable wire threading and simple and dependable wire disposal with the integrated wire chopper.
  • Highest flexibility to insert urgent machining jobs, thanks to the onboard Job Management System.
  • Perfect wire threading, even under the most difficult conditions, with the THREADINGEXPERT, a retractable device driving the wire from the upper guide to the start hole (upper surface)
  • Absolute quality results, thanks to the Integrated Vision Unit (IVU Advance). With an embedded charge-coupled device (CCD) camera linked to a backlight installed on the lower arm of the machine, IVU Advance allows pre-setting, in-process local measurements, and scanning of the contour machined.
