ABSTRACT:
In a method of positioning a wire electrode and a workpiece relative to each other in a wire cut electric discharge machine, the wire electrode is stopped under tension, the wire electrode and the workpiece are moved relative to each other, and when the wire electrode and the workpiece are brought into contact with each other, the relative movement is stopped to detect the relative position of the wire electrode and the workpiece, whereby the wire electrode and the workpiece can be positioned relative to each other with high accuracy and reproducibility.
