Abstract
An electric discharge machining method which is practiced with stable machining condition and with high machining efficiency. The condition which, in machining a workpiece, tends to place the gap between the electrode and workpiece in unstable state is detected, and the period of time for which the condition thus selected lasts is set so that the discharge energy of a pulse voltage applied across the electrode and the workpiece is reduced for the period of time thus set. Therefore, in the electric discharge machining method of the invention, the machining operation is maintained stable with high machining efficiency at all times.
