Abstract:
This wire electric discharge machine includes a servo controller which controls the relative speeds of wire electrodes to a workpiece according to a machining condition; a machining current control unit which controls discharge energy generated between the electrodes; and a machining condition setting unit which sets, as a first condition, the machining condition when approaching a machining end face, and, as a second machining condition, the machining condition when a movement distance of the wire electrode with respect to the workpiece reaches a prescribed distance, after the number of times discharge is determined to occur between the electrodes reaches a prescribed number of times within a unit time.
