Electrochemical discharge machining device and machining method

Abstract

An electrochemical discharge machining method may include electrolytically machining a tool fed by a three-dimensional tool feeder which can accurately feed a tool in three dimensions. The electrolytic machining may be performed in a current controlled mode, during which a concentration and a height of an electrolyte may be regulated. Further, the method may include performing electrochemical discharge machining of the workpiece using the machined tool in a voltage controlled mode.
