Within the frame of the EUREKA 204-project 'Laser Workstation for Surface Treatment' a flexible cell for surface treatment of complex shaped workpieces with a CO_2-high power laser has been set up tested and optimized. The report includes the following scientific and technological topics: design and development of a beam delivery system for a mechanical and electronical improved laser robot; design and integration of a working head for flexible laser beam surface treatment adapted to different process technologies (hardening, remelting, cladding); optimization of the system behaviour taking into account the optical, mechanical and electronic system characteristics; 3-dimensional surface treatment within the flexible cellSIGLEAvailable from TIB Hannover: F93B1305+a / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekBundesministerium fuer Forschung und Technologie (BMFT), Bonn (Germany)DEGerman
