Abstract

This paper deals with the effects of the nozzle shape on cutting results and fundamental characteristics of laser cutting of solid type molded composite materials, which was composed of semiconductor board and epoxy resin moldings compounds, by Q-switched single-mode fiber laser. Experimental results clarified that high speed cutting of 16mm/s could be carried out with a Laval throat nozzle with initial expansion zone. Besides, Laval throat nozzle made it possible to reduce the kerf width, and the difference of kerf width between irradiation-side and exit-side became smaller. Q-switched single-mode fiber laser proved to be useful for cutting of composite materials.
