The basic parameters in laser cutting are cutting speed, kerf width, laser power, chemistry of gas, nozzle exit pressure, nozzle design, workpiece thickness and surface quality. In oxygen assist laser cutting, the gas jet plays two roles, one is to generate additional thermal energy during formation of FeO and other oxides. This additional energy enhances the process parameters like cutting speed and thickness of the workpiece. The second role is to supply the shear force to the gas/liquid boundary to eject the molten metal formed during the cutting process. In laser cutting the major process is the instantaneous melt ejection, which is achieved by selecting appropriate operating window of the cutting speed, gas pressure, laser power, and stand-off distance etc.,
Laser power and energy density, laser scan speed and laser incident angle are some of the important parameters for laser cutting.
Of course, these will vary depending upon the material and the thickness to be cut.
