Abstract: Cutting a workpiece and producing workpiece parts are disclosed. The device has a cutting head with laser beam optics with a dynamic laser beam movement unit. A cutting head movement unit moves the laser beam over the workpiece. A control unit has a determination module to determine a movement trajectory of the laser beam, a memory unit from which at least one predetermined parameter selected from a movement parameter of the cutting head movement unit, a movement parameter of the laser beam movement unit and a parameter of a deviation of a cut contour from a predetermined contour is retrievable, and an optimization module for adjusting the movement trajectory by overlaying the movement of the laser beam via the cutting head with a high frequency beam-shaping movement of the laser beam via the laser beam movement unit based on the at least one predetermined parameter.

Abstract: A control unit for determining a dynamic laser beam shape for controlling a laser cutting machine, which is provided with a dynamic beam shaping module for varying the shape of the laser beam. The control unit includes a cutting plan interface, which is configured for receiving a cutting plan, an interface to a shape storage with a stored set of dynamic laser beam shapes, in particular more than two, and a processor which is configured for automatically calculating for each of the cutting segments an allocation to a dynamic laser beam shape of the set of dynamic laser beam shapes, wherein calculating the allocation is based on the property indicator of the workpiece and is specific for the respective cutting segment. The processor is further configured for providing control instructions for controlling the laser cutting machine by applying the determined dynamic laser beams shapes for each cutting segment specifically.
