PUNCH MACHINING PROGRAM GENERATING DEVICE, RECORDING MEDIUM STORING A PROGRAM FOR GENERATING A PUNCH MACHINING PROGRAM, AND WIRE-CUT ELECTRIC DISCHARGE MACHINE

摘要

A machining program generating device and a wire-cut electric discharge machine that can shorten a machining time to machine multiple punch shapes. A distance L from one punch shape machining end position Pe to a next punch shape machining start position Ps is obtained. When the distance L is shorter than a predetermined value, the electric discharge machining is performed between the machining end position Pe and the machining start position Ps. When the distance L is equal to or longer than that a predetermined value, the wire is cut at the machining end position Pe and connected at the machining start position Ps to restart the electric discharge machining. By continuing the electric discharge machining when the distance L is shorter than the predetermined value, it is not necessary to carry out the processes of cutting and connecting the wire, and therefore the machining time is shortened.
