<p>A taper machining controlling method and system for a wire cut discharge machining apparatus for machining the taper due to an electric discharge at a work (WK) by moving the work (WK) relative to a wire (WR) and applying a voltage between the work (WK) and the wire (WR). When a relative movement instruction for the work (WK) and the wire (WR) and a movement instruction for an upper guide (UG) of the wire (WR) are applied from a machining instruction, an interpolated distance between the upper guide (UG) and the lower guide (DG) of the wire (WR) and the interpolated distance at the predetermined plane of the work (WK) are calculated from the machining instruction. Then, the moving speed of the upper and the lower guides (UG) and (DG) are obtained to move the wire (WR) relative to the work (WK) at the instructed speed and to simultaneously start and finish the movements of the upper and the lower guides (UG) and (DG) with the interpolated distance and the instructed speed, thereby moving both guides (UG) and (DG). </p> |
