The new PCD Edge system from Methods EDM (Sudbury, MA) allows quick and precise profiling of polycrystalline diamond (PCD) cutting tools using a Fanuc iC Series wire EDM machine. The system consists of advanced programming/probing/cutting software, a microfinish power supply/generator optimized for cutting PCD, a Hirschmann rotary axis, a Renishaw probe (mounted on the EDM machine), and a tool clamping system. Ideal 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 (restore profiles on) worn PCD-tipped tools. This system is quick and easy to use for even the most complex tools or profiles. Users can design tool edge contours on their own CAD system—eliminating the need to learn a new system or change procedures. Intuitive and user-friendly, the system provides special input masks to simplify parameter selection, program simulation, design modification, and verification. With no special programming knowledge, the user can create up to eight profile sections with specific parameters for each. Sophisticated software and a rotary axis permit adjustment of the relief angles on each contour element as well as automatic measuring (with feedback) of 3-dimensional PCD tip positions (rake and shear angles). With optional control software, the entire process (probing through program generation through cutting) can be automated for unattended operation.
