Laser cutting is the popular unconventional manufacturing method widely used to cut various engineering materials. In this work CO2 laser cutting of AISI 314 satinless steel has been investigated. This paper focus on the investigation into the effect of laser cutting parameters like laser power, assist gas pressure, cutting speed and stand-off distance on surface roughness, hardness and kerf dimensions like kerf width, kerf ratio and kerf taper in CO2 laser cutting of AISI 314 stainless steel.
