Investigation of the Dependence of the Technological Parameters of Laser Cutting to Minimize the Deviation from the Nominal Dimensions of the Parts

The purpose of the published research is to investigate the dependence of the technological parameters (cutting speed, focal length, and gas pressure) of fiber laser cutting to obtain the minimum deviation of the diameters of the parts from the nominal dimensions. The result is a mathematical model and optimized values for setting the fiber laser cutting machine’s technological parameters for the given material type. The optimized laser cutting parameters also depend on the kind of material. The entire research is focused on developing a global auto-calibration system for optimizing laser cutting parameters for different thicknesses and types of materials.
