Abstract

The geometry of the cutting front was determined with a high temporal and spatial resolution during cutting of 10 mm thick stainless steel with a solid-state laser. The geometry was reconstructed using the information of the polarization state of the thermal radiation emitted from the process zone. This reconstruction of the geometry makes it possible to investigate the influence of process parameters on the geometry of the cutting front, including structures on the front and the global angle of inclination.
