ABSTRACT:
In combining electrical discharge machining (EDM) and electrochemical machining (ECM) the use of a strong electrolyte has, in the invention, been found possible. In one embodiment a pulse generator applies an intermittent voltage between an electrode and a workpiece causing both EDM and ECM to take place when a strong electrolyte is interposed in the gap between the electrode and the workpiece. At the onset of arcing a discharge monitor removes the voltage. A wire-cutting machine and method combining EDM and ECM are also described.
