The PCD Edge system allows the profiling of polycrystalline diamond (PCD) cutting tools using a Fanuc iD series wire EDM machine. The system consists of programming/probing/cutting software; a microfinish power supply/generator for cutting PCD; a Hirschmann rotary axis; a machine-mounted Renishaw probe; and a tool clamping system. Designed for PCD tooling OEMs, shops that maintain their own tooling and contract sharpening services, the system can be used to create original profiles or to sharpen worn PCD-tipped tools. The system allows users to design tool edge contours on their own CAD systems, eliminating the need to learn a new system or change procedures. It provides special input masks to simplify parameter selection, program simulation, design modification and verification. With no advanced programming knowledge, the user can create as many as eight profile sections with specific parameters for each, the company says. The software and a rotary axis permit adjustment of the relief angles on each contour element as well as automatic measuring (with feedback) of 3D PCD tip positions such as rake and shear angles. With optional control software, the entire process can be automated for unattended operation, the company says.
