ABSTRACT:
So that the path (BB, V1 to V7) for a rotable polygonal punching tool (WZ) can be determined easily, the workpiece contour (K), the dimension of the tool (x, y), the position of the axis of rotation (x/2, y/2) and the sense of direction of the machining are set by the operator into a numerical control (ST). An equidistant track (BB) is therefrom determined by the control (ST), such as is customary for milling operations. This track (BB), however, is corrected in the vicinity of corner of the workpiece contour (K) by the control (ST) in such a manner that punching optimized with respect to distance and time and with high contour fidelity is made possible.
