FINISH PROCESSING METHOD IN WIRE CUT ELECTRICAL DISCHARGE MACHINE AND WIRE ELECTRICAL DISCHARGE MACHINE

摘要

When performing a finishing process by wire cut electric discharge machine , the approach of a finished part from the machining starting position the program proceeds to block movement in the discharge unit off (OFF) state ( dry run ), and the shape of the discharge in the next processing block in the on (ON) state . By doing so, the pane on the processing surface of the workpiece by the approach groove 22 can be prevented from being formed . ;
