Abstract
A wire electric discharge machine capable of adjusting spacing between a nozzle and a workpiece without manual operation and without causing damage to a machine and a workpiece. The wire electric discharge machine includes wire supply apparatus for supplying a wire electrode through the wire guide toward the workpiece; wire supply-amount measuring apparatus for measuring a supply amount of the wire electrode; wire front-end detecting apparatus for detecting a front end of the wire electrode being supplied by the wire supply apparatus at a wire front-end detecting position; and wire contact detecting apparatus for detecting contact of the front end of the wire electrode with an upper surface of the workpiece. A position of the upper surface of the workpiece is determined based on the wire front-end detecting position and a supply amount of the wire electrode measured by the supply amount measuring apparatus from when the front end of the workpiece is detected by the wire front-end detecting apparatus till the contact of the front end of the wire electrode with the upper surface of the workpiece is detected by the wire contact detecting apparatus.
