ABSTRACT:
An electrical discharge machine for applying a pulsed voltage to a machining gap between an electrode and a workpiece disposed opposite thereto. An insulating dielectric fluid, including either oil or water with a compound additive, is disposed in the gap. A first voltage is applied to the machining gap. If a predetermined period of time passes and a discharge has not occurred at the machining gap, then a second voltage, opposite in polarity to the first voltage, is applied to the machining gap.
