A solid-state ultraviolet laser with a circular processing path was used for profile cutting on soda-lime glass plates. Simulation results show that decreasing scanning speed and path spacing and increasing circular processing path frequency yields a smooth cutting edge for the same processing length. Profile glass-plate cutting shows the machined surface with more obvious roughness and numerous microcracks near areas of laser focus than in areas of laser defocusing. This phenomenon is attributed to high laser-energy density and strongly affecting surface roughness.
