TRAJECTORY DETERMINATION METHOD FOR NON-PRODUCTIVE MOVEMENTS
A method of controlling a non-productive movement of a tool from a starting position to an end position in a travel envelope of a machine tool includes the steps of a) providing a collision-free first trajectory for the non-productive movement of the tool, b) determining a second trajectory that is...

| description | A method of controlling a non-productive movement of a tool from a starting position to an end position in a travel envelope of a machine tool includes the steps of a) providing a collision-free first trajectory for the non-productive movement of the tool, b) determining a second trajectory that is improved over the first trajectory with regard to a selectable target parameter using an algorithm, and c) checking the second trajectory for collisions and, if the second trajectory is free of collisions, providing an instruction corresponding to the second trajectory. The first trajectory in step a) includes plural rectilinear segments and the second trajectory in step b) includes a polynomial segment and, if the second trajectory is not free of collisions in step c), steps b) to c) are repeated so that the algorithm is provided with a modified model of the travel envelope in a repeat of step b). |
