| Abstract: | In this paper a bulge model was gained and then the relation between bulge and laser power and processing time.The simulation results show that increasing laser scanning speed,reducing the irradiation time and preferring lower laser power can reduce the bulge height.The simulation results can direct the improvement of surface quality for laser machining PMMA microchannel. |
