Abstract

PURPOSE: To improve the operation rate and operation ability of the wire electric discharge machining in the title by moving a wire electrode until the contact of the wire electrode with a work is released if they have already been in contact with each other at the start point of the machining, and starting the machining while the wire electrode is returning to the start point of the machining after the release of the contact.
CONSTITUTION: When the contact of a wire electrode with a work is detected at the start point of machining by a device 50 for detecting a contact at the start point of machining according to a signal from a machining voltage evaluation device 46, a device 51 for releasing a contact at the start point of machining is operated. Then a mobile locus as a contact avoidance locus which has already been saved in an NC tape 49 is read by an NC program interpretation device 48. According to the read program, the wire electrode is shifted by means of a motor controller 45. And when the contact is released in accordance with a machining start hole, the wire electrode returns to the start point of machining by means of a machining start point restoration device 52 while performing electric discharge machining. As a result, the operation rate and operation ability of the wire cut electric spark machine concerned can be improved.
