Title:
WIRE ELECTRIC DISCHARGE MACHINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/145217
Kind Code:
A1
Abstract:
A wire electric discharge machining device comprises a wire electrode disposed spaced from an object to be machined and a constant voltage power supply for supplying a high-frequency voltage between the object to be machined and the wire electrode, and generates electric discharge between the object to be machined and the wire electrode by the application of the high-frequency voltage to machine the object to be machined. The wire electric discharge machining device further comprises: a current measuring means for measuring the value of current flowing from the constant voltage power supply; a determination means for, based on the measured current value and the variation value of the current value, determining an inter-electrode state that is a state between the object to be machined and the wire electrode; and a control means for, based on the determined inter-electrode state, controlling the space between the object to be machined and the wire electrode.
