Abstract
A wire electric discharge machine configured to perform machining while swinging a wire electrode and comprising a swing frequency counting unit configured to count a swing frequency of the wire electrode, a machining stop unit configured to stop machining by the wire electrode when the swing frequency reaches a predetermined value, and a machining resuming unit configured to drive an axis drive unit to move the wire electrode by a predetermined distance relative to a workpiece after the machining is stopped by the machining stop unit and thereafter to return the wire electrode to a position where the machining is stopped and resume the machining.
Claims6
A wire electric discharge machine which comprises a wire electrode, a wire guide supporting the wire electrode, and at least one axis drive unit configured to swing the wire electrode relative to a workpiece and machine the workpiece while swinging the wire electrode relative to the workpiece, the wire electric discharge machine comprising:
- a swing frequency counting unit configured to count a swing frequency of the wire electrode;
- a machining stop unit configured to stop machining by the wire electrode when the swing frequency reaches a predetermined value;
- and
- a machining resuming unit configured to drive the axis drive unit to move the wire electrode by a predetermined distance relative to the workpiece after the machining is stopped by the machining stop unit and thereafter to return the wire electrode to a position where the machining is stopped and resume the machining.
