Abstract:
The invention relates to a method ( 100 ) for determining an optimised trajectory for a non-productive movement of a tool ( 10 ) of a machine tool, from a starting position ( 12 ) to an end position ( 14 ). The non-productive movement is carried out in a spatially restricted travelling area ( 20 ) which is represented by geometric conditions. The method according to the invention is executed with the avoidance of collisions and comprises the step of determining a first trajectory ( 32 ) of the tool ( 10 ) by means of a travel-finding algorithm. In this step, the first trajectory ( 32 ) is optimised for the non-productive movement with respect to at least one selectable target parameter.

Claim (Index 27):
A machine tool comprising at least one tool and a control unit configured to cause the tool, based on received program instructions, to execute an optimized trajectory for a non-productive movement of the tool from a starting position to a target position in a spatially delimited travel envelope which is modeled by geometric conditions while avoiding collisions, wherein the optimized trajectory is determined by:\n a) establishing, with a pathfinding algorithm that does not take into account design features of the machine tool, a first trajectory of the tool, wherein the first trajectory is optimized for at least one selectable target parameter in the non-productive movement; b) establishing a second trajectory by applying to the first trajectory a filter that takes into account dynamic characteristics of the machine tool; c) identifying a collision when a geometric condition which models the travel envelope is violated at a point of the second trajectory, wherein, when the method is first executed, the geometric condition corresponds to surfaces of at least one obstacle delimiting the travel envelope, while taking into account safety margins; d) determining a correction condition that applies to the geometric condition and modifying the correction condition; and e) repeating steps a) to d) until the geometric condition in step c) is met for all points of the second trajectory.
