PROBLEM TO BE SOLVED: To provide a wire electric discharge machining method and a wire electric discharge machine, for highly precisely and easily machining a cutting tool with ultra-hard material fixed thereto.;SOLUTION: A touch sensor 3 mounted to an upper wire guide 14 is positioned at a measurement position by driving an X axis and a Y axis for horizontally moving the touch sensor 3 relatively to a tool to be machined having a PCD (polycrystalline diamond) tip 101 fixed to a tool body 100 according to a measurement program generated based upon a machining program (a). A front end 3b of a detector 3a is lowered to a rotation center height of a rotary shaft by movement of a vertically moving Z axis, and positioned (b). The rotary shaft 22 is rotated in a direction in which a rake face of the cutting tool comes into contact with the front end 3b (c). Rotary shaft coordinate information at the point of time of the contact is read in a control device 50, the machining program is generated again based upon data on rotary shaft coordinates acquired according to the measurement program, and the cutting tool is subjected to discharge machining at the position where the rake face position is measured.;COPYRIGHT: (C)2013,JPO&INPIT
