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 laserworkstation with a robot guided, free moveable laser beam guiding system, realised at the Fraunhofer-Institute for Manufacturing Engineering and Automation (IPA), the different components of a flexible laserworkstation 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. Investigations concerning the static and dynamic behavior of the system will show the requirements for a design of a reliable laser beam guiding system. A consideration of the economy of different laserworkstations delivers economic indexes which show the cost ratio between the different variants.
