PURPOSE:To raise the processing efficiency, by performing a cutting work, as the cutting line passes a point which indicates the depth which is equal to the bearing length when a back relief inclined surface is formed and after that, processing the bearing surface. CONSTITUTION:When a back relief inclined surface 6 is formed, a cutting processing is performed as controlling the position and the angle of inclination of a wire electrode 12, as a margin to process of a bearing surface 5 is left. That is, the position of the wire electrode 12 is calculated, according to values of coordinates of P of the bearing surface 5 which is to be processed, and the bearing length l1. Next, when the bearing surface 5 is processed, the processing is performed as the depth of cut formed by the wire electrode 12 is not deeper than the cut width DELTAd. In this way, man-hours required in the process of manufacture can be drastically decreased, and the precise processing can be performed. |
