Laser cutting experiments were studied using an industrial laser cutting system including a 1 kW CO2- laser and a two axis CNC cutting table. Oxygen assisted cutting was carried out with a laser beam in fundamental mode focussed by a 5 inch ZnSe lens. The materials investigated include deep drawing steels, mild steels and stainless steels. The influence of beam polarization and cutting mode (cw, pulsed and superpulsed) on the cut quality and the development of the heat affected zone is demonstrated. Lateral accuracy, microgeometry of the cut and mechanical properties of cut samples are reported as function of process parameters. As was shown earlier, laser cut samples exhibit finished product quality and mechanical properties that fulfill the requirements of DIN and ASTM standard values. Examples of 3D cutting applications for automobile industry are given.
