Beschreibung
Zusammenfassung:	A system for machining materials by means of laser beam includes a deflection device for deflecting the laser beam and a wobble device configured to superimpose a wobble movement of the laser beam with a wobble figure and a wobble frequency onto a feed movement of the laser beam corresponding to a machining path by controlling the deflection device. The wobble device is configured, for carrying out the wobble movement, to control the deflection device according to a compensated wobble movement. Control values for a deflection of the laser beam along the wobble figure are adapted as a function of the wobble frequency and/or a path speed of the wobble movement that varies along the wobble figure is adapted as a function of a position of the laser beam in the wobble figure and as a function of the wobble frequency.
