<p>A block in an electric discharge machining program is read out and analyzed, and when determined that a machining route correction command is issued to correct the machining route at a corner formed by consecutive first and second machining blocks, the machining route is corrected such that the end point of the first machining block, an extension point obtained by extending the first machining block from the end point thereof by a predetermined distance in the machining advancing direction, and a new start point obtained by partially removing the second block by a predetermined distance from the start point thereof are connected. Then, the wire electrode is moved with respect to the workpiece, following the corrected machining route.</p> |
