Method for collision checking of a machining process with a substitute workpiece

A method for collision checking of a machining process, comprising the steps of:

• providing a process-specific cycle for the machining process, during which cycle multiple machining components are to be moved relative to one another with at least one machine axis on a machine tool, wherein the machining components comprise at least one workpiece and one tool, and at least during a part of the process-specific cycle the workpiece is to rotate about a workpiece axis and the tool is to rotate about a tool axis;
• in the process-specific cycle, identifying at least one checking position, which checking position is checked for collisions with respect to the machining components;
• wherein the checking position corresponds to a relative position of the machining components set with the at least one machine axis;
• and wherein, in order to check a respective checking position for collisions, reproducing the relative position of the machining components, wherein one or more substitute machining components are used during the reproducing, which are each a replica or partial replica of the corresponding machining component;
• wherein the one or more substitute machining components comprise a substitute workpiece which is a partial replica of the workpiece;
• wherein in the substitute workpiece the workpiece is replicated at least over an axial partial region only over a part of a circumference of the workpiece;
• and
• wherein, in the reproduced relative position, the substitute workpiece is rotated about its workpiece axis.
