Abstract

The invention relates to a method for predicting the tilt inclination of a workpiece part that is being cut free from a remaining workpiece using a machine tool during a machining process, and that rests on one or more supports, said method comprising the following steps: determining one or more possible tilt edges about which the workpiece part being cut free might tilt. For at least one potential tilt edge, particularly for each potential tilt edge, determining tilt moments that act on the workpiece part in different states of the machine tool, and on the basis of the determined tilt moments, determining whether the workpiece part would tilt about a tilt edge.
