PURPOSE:To enable wire cut electric discharge machining of a work to be performed into a three-dimensional shape, by performing the wire cut electric discharge machining providing a main spindle stock, serving as a work driving means, on an XY table so that the work is rotated around the rotary axial center. CONSTITUTION:When a work 4 is machined into the shape of a linear woven surface forming its lower bottom surface into a circle while upper bottom surface into an oval, the work 4, which is fixed to a rotary axial center 5 further rotated by a work driving means 7 around the rotary axial center 5, changes an angular position with respect to a wire 2. Next the wire 2 is tensely provided between a pair of guide rollers 3, and the guide rollers 3 are numerically controlled to a route programmed by a machining position setting means 6 consisting of a servomotor. And wire cut electric discharge machining, which is performed through machining fluid between the wire 2 of machining unit and the work 4, obtains the work 4 of linear woven surface shape, having a programmed optional shape, to be enabled to be machined into a three- dimensional shape.
