Abstract

Material processing by laser still offers a wide topic for investigations since interaction between light and material is very sensitive to inner and outside influences. Big efforts have to be taken to control the quality of laser cut edges, up to 6 mm. Using obtained optical signals from the cutting process efficient control highly depends on sophisticated mathematical methods. We present first contexts between two sensor signals of different wavelengths by the use of different mathematical algorithms. Important is the well done combination of these signals to achieve controlling rules both for the cutting speed and the laser power considering computation time for its evaluation.
