Abstract

The laser is a non-contacting, forceless tool which is nearly free from wear. In regard to its tasks and its potential for process automation due to ease of control of the laserparameters, laser processing seems to be predestinated for flexible manufacturing. By the use of free moveable, robot guided laser beam guiding systems, the laser as a tool, offers a new potential for widely varied tasks. In an overview on existing concepts for laser beam guiding systems, the possibilities for laser beam handling are discussed and system concepts of coupling laser beam guiding systems to a robot are presented. With the help of a pilot laser workstation, realised at the IPA, the different components of a flexible laser workstation are specified. Basing on this the principal explanations of robot guided laser beam guiding systems are introduced. Different kinematic diagrams show the influence of the combination of laser beam guiding system and robot kinematic due to the workenvelope of the entire system. Measurements of vibrations, analysing the frequency spectrum and the acceleration force on different characteristic points of the laser beam guiding system are carried. out. Further more the vibrations have been brought in comparison with the beam pointing stability and all these measurements have been undertaken by the consideration of the corresponding cutting results.
