METHOD OF CUTTING OUT PART WITH MAKING PARTIALLY WELDED SPOTS IN WIRE-CUT ELECTRICAL DISCHARGE MACHINING

摘要

The method for machining a workpiece cutting residue in the wire electric discharge machining according to the present invention is a method for machining a workpiece cutting residue in a wire electric discharge machining method in which a cutting object 26 is prevented from dropping from the workpiece 6 and the cut residual material portion 26 is not machined again by electrical discharge machining , The welded portion 20 is broken by an external force to peel off the cutting water 26, thereby shortening the machining time and improving the machining efficiency. The method for machining the workpiece cutting residues is a method for changing the electrical machining conditions applied between the wire electrode 5 and the workpiece 6 from at least one of the predetermined machining shapes of the workpiece 6 to a welding cycle And melts a part of the wire electrode 5 to melt the workpiece 6 and the cut material 26 with the wire electrode melt so that the cut material 26 is held by the welded portion 20 on the work 6.
