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 having a periodic motion of the electrode relative to the workpiece; wherein the 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.
Claims7
An electric discharge machine for machining a workpiece, disposed within a machining tank of the electric discharge machine, using 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, said electric discharge machine comprising:
- a detector which detects a change in a state quantity of a main body of the electric discharge machine, the change in the state quantity caused by a reactive force produced by a machining operation in the gap between the electrode and the workpiece;
- and
- circuitry which changes machining conditions associated with the workpiece in accordance with a detected value of the state quantity to reduce the change in the state qualitity.
