ABSTRACT:
An electric discharge machine for machining a workpiece by an electric discharge by supplying a machining fluid to a gap between an electrode and the workpiece and supplying pulses to the workpiece while providing the electrode with a jump motion, said jump motion being a periodic motion of the electrode relative to the workpiece; wherein said electric discharge machine detects a state quantity caused in a main body of the electric discharge machine by a reactive force produced by a machining operation in the gap between the electrode and the workpiece and changes machining conditions of the workpiece in accordance with a detected value of the state quantity.
