<p>PURPOSE: To accurately machine a part to desired shape dimensions even in the case of a complicated cutting course by varying further a first parameter or stopping its variation in the case where the first parameter arrives at a final desired value when the value of the second parameter arrives at a scheduled threshold. CONSTITUTION: In the case where the image of a state inside a slot under a machinging process is given and it reaches a scheduled threshold, a second parameter varied again is continuously determined according to at least a variation based on the scheduled quantity Q of the value V of a first parameter. Next, when the value of the second parameter arrives at a scheduled value again, the value of the first parameter is gradually varied to the final desired value V' or until the occurrence of a scheduled number of gradual variations, and a relative motion between an electrode wire 1 controlled on the final scheduled value V' where the first parameter reaches and a workpiece 2 is continuously carried out. When the wire 1 arrives at a next scheduled point, the variation term in an opposite direction of the value of the first parameter is continuously compared with the reference threshold of the second parameter.</p> |
