Method of operating a wire electric discharge machine for taper-machining by tilting the workpiece

In a wire electric discharge machine, a workpiece mounting unit mounts a workpiece tilted at a preset angle to a plane based on two orthogonal axes, X- and Y-axes. An XY-coordinate system is tilted at the preset angle so that it is transformed into an X'Y'-coordinate system. A machining co...

Zusammenfassung:	In a wire electric discharge machine, a workpiece mounting unit mounts a workpiece tilted at a preset angle to a plane based on two orthogonal axes, X- and Y-axes. An XY-coordinate system is tilted at the preset angle so that it is transformed into an X'Y'-coordinate system. A machining command value commanded by a machining program is corrected based on the X'Y'-coordinate system. Thus, the tilted workpiece is taper-machined with a wire electrode kept substantially perpendicular to the XY-plane (table surface).
