文摘

Mathematical models that provide an adequate description of the effect of laser cutting parameters on the roughness of the cut surface with no burr, the extent of the heat-affected area, and the nonperpendicularity of the cut surface are devised. Nomograms that allow one to select the laser cutting regimes designed to minimize the surface roughness, the heat-affected area, and the nonperpendicularity for sheets of St. 3 steel of different thickness are proposed.
