Patent ID: 8242403

Claim:
A method for controlling a wire electric discharge machine comprising the steps of: determining of at least one predefined contour deviation (E smax ) of a predefined contour to be cut into the workpiece; determining a curvature of at least one geometry element defining at least one section of the contour to be cut into the workpiece; calculating a displacement (s) of an upper guide (WG U ) and a lower wire guide (WG L ) based on the predefined contour deviation (E smax ) and on the curvature of the at least one predefined geometry element; and setting the displacement (s) by moving the upper guide (WG U ) relative to the lower wire guide (WG L ) such that the wire electrode guided by the upper (WG U ) and lower wire guides (WG L ) is inclined in a current cutting direction of the workpiece during cutting of the geometry element into the workpiece.
