Electrical discharge machining method for wire cut

Abstract

Abstract PURPOSE:To prevent a separated workpiece from dropping by leaving only the one part of the workpiece in its height direction while inclining a wire electrode in the wire travelling direction just before completion of the electrical discharge machining for wire cut. CONSTITUTION:Electrical discharge is generated between a workpiece 1 and a wire electrode 5 supported with wire guides 7, 8 and the workpiece 1 is sent, allowing it to be cut and machined into a closed loop shape. When a residual part 6 not yet machined changes into a prescribed width just before the completion of machining, only the lower side wire guide 8 is sent in the machining direction while keeping the upper side wire guide 7 to stop, and only the one part of a residual part 6' to be machined is left in its height direction with the completion of machining. Thereafter, the workpiece is separated by striking it with a hammer or by cutting it with a fretsaw.
