ABSTRACT:
Supply of a wire electrode, application of a detection voltage, and binarization and sampling of the detection voltage are started, so as to start advance of the wire electrode from the position A toward a workpiece. The position of the wire electrode when a sampling value (low level) is detected for the first time is designated as a position B, and the wire electrode is advanced from this position by a predetermined distance P1, and is stopped at a position C. Retreat of the wire electrode is started from the position C, and a position Q where the sampling value has changed from the high level to the low level is stored as a contact
oncontact boundary position. Further, retreat of the wire electrode is continued, and the wire electrode is stopped at a predetermined separating position D, to thereby finish the processing.
