Abstract
An EDM head has a single servo-controlled electric motor and a high ratio gear system that drives a wire electrode during both an EDM machining operation and a wire erosion compensation operation. An associated control system can be programmed to selectively drive the electrode to compensate for wire erosion and to control blind hole breakout.
