Tebis CAD/CAM for sinker EDM

Sinker EDM is the manufacturing method of choice if sharp inner corners or deep cavities are required in die and mold manufacturing. This is achieved by milling a negative of the geometry as an electrode in a conductive material (usually copper or graphite). The application of high electrical voltage between this electrode and the workpiece removes material from the workpiece through electrical discharge. Because several electrodes are usually required to create a cavity in sinker EDM, the number of parts to be manufactured as well as their complexity quickly increase.
