Marble cutting with cw CO2 laser

摘要

Abstract: In this paper we present results of marble cutting with high power CO$- 2$/ laser. The dependence of various parameters such as thickness of marble, laser power, cutting speed, assist gas and its pressure on cutting process was studied. Structural properties of marble like crystal size have been found to affect the cut quality. The average severance energy (P/vt, P $EQ laser power, v $EQ cutting speed, t $EQ thickness) for marble was approximately found to be 9.0 J/mm$+2$/. This agrees very closely with the calculated value based on energy balance.!5
