Plasma cutting is an effective way to cut hard metals. In this process, three output parameters cutting width (kerf), surface roughness (Ra) and heat-affected zone (HAZ) are critical factors which A Review on Plasma Arc Cutting (PAC) Process Parametersvariance it is found that the surface roughness and conicity are mainly affected by the cutting height, whereas the heat affected zone (HAZ) is mainly influenced by the cutting current. Miroslav Radovanovic et al  had done a modeling of the plasma arc cutting process using
Experimental results show that the depth of cut does not affect either surface finish or burr formation. A proposed new sideflow model shows the dominant effect of cutting-edge radius and feed rate on surface finish, while tool edge roughness, coating and feed rate have the Characterization and Modeling of Surface Roughness and Experimental results show that the depth of cut does not affect either surface finish or burr formation.

Critical Heat Flux in Submerged Jet Impingement Boiling of The American Society of Mechanical Engineers, 1995, Surface Texture (Surface Roughness, Waviness, and Lay), An American National Standard, ASME B46.1-1995. Cutting of tungsten plate for fusion device via pre-mixed Second, the jet pressure had less effect on surface roughness than the transverse speed. With an increase of jet pressure, the surface roughness at transverse speeds of 2.5 mm/min and 7.5 mm/min showed an initial decrease, which was followed by an increase. The cutting surface roughness at a transverse speed of 5 mm/min decreased slowly.
