Claim Text:
1. A method of forming, by wire electric discharging machining, an ultra-hard material that is fixed to a cutting tool into a cutting blade according to a machining program executed by a wire electric discharge machine performing a taper machining, wherein the wire electric discharge machine comprises: the method comprising: generating a measurement program for setting, along a machining path instructed by the machining program, measurement points at which contact between a face of the ultra-hard material and a probe end section of the touch sensor is detected at a rotation center height of the rotating shaft, said measurement points including for each of the measurement points, regenerating a machining program from the path coordinate position information and the rotating shaft coordinate information that are stored for each of the measurement points; and forming a cutting blade through wire electric discharge machining of the ultra-hard material by the wire electrode that is stretched by the upper and lower wire guides, according to the regenerated machining program.
