Patent ID: 8334479

Claim:
A system for high-dynamic 3D machining of a workpiece by means of a laser beam, comprising a buckling arm robot with a robot frame and an articulated arm, the stationary end of which arm is attached to the robot frame and on the free end of which arm a machining lens system is disposed, which lens system defines an optical axis, and a fiber optic cable which is connected to the stationary end of the articulated arm so as to be able to couple a laser beam with a beam axis into the articulated arm, characterized in that the fiber optic cable is indirectly connected via an alignment unit to the stationary end of the articulated arm and the alignment unit comprises a collimating lens system and at least two alignment mirrors, each of which can swivel about at least one axis of rotation and move along at least one axis of translation, with the axes of rotation and the axes of translation being at right angles to each other, so that the beam axis can be made to coincide with the optical axis.
