ABSTRACT:
An interelectrode distance controlling device in an electric discharge machining apparatus which is capable of automatically setting the proportional constant for a drive unit for driving an electrode to machine a workpiece, so that the machining is performed with high accuracy and smoothly. Such an interelectrode distance controlling device, detects the oscillation of a system in an electric discharge machining apparatus during machining, and the device automatically sets the proportional constant to an optimum value in a range within which no oscillation occurs with the system.
