Surface morphology of non-metallic solid materials after laser carving

Cui Chengyun; Cui Xigui; Shi Guifeng

Three typical non-metallic materials of the wood, marble and synthetic glass were carved by CO2 laser. The effects of laser parameters on the carving surface morphology were researched, optimizing the laser carving process parameters of non-metallic materials. The results show that the carved depth is gradually increased with the increase of laser power; for the wood and synthetic glass with low melting point, the lower laser power is beneficial to obtain the notch of the neat and beautiful edge, but too large laser power can make the wood appear black or even overburning phenomenon, and make the synthetic glass appear corrugated and uneven phenomenon; for the brittle marble with high melting point, the higher laser power results in the clear notch, the neat sharp edge and no slag formation, however, when the carving speed is too low, the carved edge is rough and not neat.
