Abstract

In this paper, the laser processing technology and quality control of hot stamped parts made of high-strength steel are studied. Through in-depth on-site practice and analysis, combined with the exploration of laser cutting burrs on complex curved parts, a solution to the causes of cutting burrs is proposed. The research results show that factors such as cutting corner height and focal point position, cutting nozzle and cutting air flow, deviation between the digital model and the actual workpiece, cutting power and corner speed, and the influence of the positioning of the workpiece fixture play a key role in laser cutting. To address these problems, this study proposes effective solutions by adjusting the focal point position, optimizing the cutting nozzle type, and changing the cutting parameters. Eventually, after practical verification, these measures drastically reduce the corner burrs and solve the problem of burns on the cut parts while improving the efficiency of part debugging, so that the cutting quality is significantly improved.
