ABSTRACT:
An electrical discharge machine, which performs electrical discharge machining by applying a voltage pulse across an electrode and a workpiece, includes an adaptive control unit for maintaining the machine in a predetermined machining state at the start of the electrical discharge machining operation. The adaptive control unit detects an electrical discharge machining fault during the start of the electrical discharge machining process, adaptively changes the machining conditions to avoid faults, and restores the original machining conditions thereafter.
