ABSTRACT:
The number of electric discharge pulses is detected every given period. A deviation between the detected number and a target number of electric discharge pulses is obtained. Based on the obtained deviation, a correction value for the correction of a machining path in a direction normal to the machining path is calculated, whereby a corrected path is obtained. A wire electrode is moved relatively to a workpiece along the corrected path.
