Abstract:
1. A process for machining workpieces with a moving laser beam, the process comprising: holding a laser tool, that emits the laser beam, by a multiaxial mechanical manipulator at a manipulator hand at a spaced location above the workpiece; moving the laser tool along a predetermined path along the workpiece by a displacing motion of the manipulator and during the displacing motion of the manipulator; superimposing a compensating motion of the laser beam to the displacing motion during the displacing motion with the compensating motion being at least partially oppositely directed to the displacing motion wherein the compensating motion of the laser beam is performed by a pivoting motion of the manipulator hand about a hand axis; and continuously displacing the laser tool with the displacing motion of the manipulator during an intermittent machining of the workpiece in which machining phases and transport phases alternate.
