Abstract
A wire electric discharge machine corrects a machining route according to an angle between two moving blocks that form a corner portion. A correction distance and a return distance are computed based on a detected corner angle. The correction is implemented so that an end point of a block to be machined first is extended according to the correction distance, and a portion extending from a start point of a block to be machined subsequently to an intermediate point of this block is removed according to the return distance. A machining route is created so that the end point of the new block created by the extension is connected to the start point of the other block created by the removal, and the wire electrode is moved along the machining route relative to a workpiece.
