1. A method for processing a workpiece using a device, the device comprising a processing machine configured for three-dimensionally processing the workpiece and the device further comprising a tool head having a tool, the tool head being movable about at least a first axis and a second axis, the method being carried out by the device, the method comprising:
B) capturing input data concerning a contour of the workpiece, concerning a contour of the tool head, concerning a distance between the tool head and the workpiece, concerning the first axis, and concerning the second axis;
C) processing the input data to form feature data;
D) processing the feature data in a machine learning algorithm of the device;
E) outputting a forecast from the machine learning algorithm regarding a collision of the tool head with the workpiece or some other part of the processing machine, wherein, in a case of a collision forecast in the method step E), collision-free input data of the first axis and second axis are output in the method step E), wherein the collision-free input data corresponds to a pivoting of the first axis and the second axis.
