Реферат: ABSTRACT OF THE DISCLOSURE A discharge machining apparatus adapted to permit the supply of discharge current to be cut off without increas-ing electrode consumption. Arrangements are made to gra-dually increase the level of discharge current, rather than maintaining the current level of discharge pulse. By doing so, electrode consumption becomes independent of the pulse width of the discharge pulse, so the discharge current can be cut off immediately after an abnormal state occurs, eliminating the danger of deteriorating the quali-ty of the machining surface of a workpiece.
