EXPERIMENTAL STUDIES ON CO2 LASER CUTTING OF LOW ALLOY STEEL USING OXYGEN AS ASSIST GAS
CO2 laser cutting of low alloy steel sheets is considered and the effect of cutting speed and material thickness on the kerf width and the surface roughness is examined. It is found that the surface roughness decreases by increasing cutting speed while the kerf width changes slightly with increasing cutting speed. Also the results show that the surface roughness and the kerf width increase by increasing material thickness while the cutting speed decreases by increasing material thickness.
