Abstract

A method for controlling a wire electric discharge machine comprising the steps of:

determining of at least one predefined contour deviation (Esmax) 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 (WGU) and a lower wire guide (WGL) based on the predefined contour deviation (Esmax) and on the curvature of the at least one predefined geometry element; andsetting the displacement (s) by moving the upper guide (WGU) relative to the lower wire guide (WGL) such that the wire electrode guided by the upper (WGU) and lower wire guides (WGL) is inclined in a current cutting direction of the workpiece during cutting of the geometry element into the workpiece.
