First Claim
Patent Images
1. A control apparatus that controls a wire cut electric discharge machine having an electrode moving device that moves a wire electrode relative to a workpiece, the control apparatus comprising:
- a controller that;
changes a discharge gap generated by the wire electrode;
inserts a correction block into a corner of a movement path where the wire electrode is moved by the electrode moving device, wherein the correction block does not correspond to a contour of the workpiece to be machined; and
sets a changing position to change the discharge gap based on the correction block when the discharge gap needs to be changed before and after the corner.

Abstract
In a wire cut electric discharge machine, a correction block is inserted into a corner of a movement path where the wire electrode is moved by the electrode moving device. The correction block does not correspond to the contour of the workpiece to be machined. When it is necessary to change machining condition such as the voltage to be applied to the wire electrode before and after the corner, a changing position to change the machining condition is set on the correction block.
