摘要
激光切割以其切割范围广、速度高、切缝窄、热影响区小、加工柔性好等优点而广泛应用于各种加工领域,是激光加工中发展最为成熟的一种技术。基于激光切割理论,依靠大量实验完成了对激光切割工艺参数的优化。对影响激光切割表面质量的主要因素,如工作气体,激光功率,光斑模式,辅助气体,离焦量及扫描速度进行分析对比,以切口的表面粗糙度作为衡量的指标,总结出该实验材料的最优工艺参数。
Laser cutting has been found widely using in the manufacturing industry because of its many advantages,such as the wide-range cutting scale,high cutting speed,narrow cutting kerf.small Heat-Afected zones,and flexible cutting process and so on.In this subject,we optimizate the process of laser cutting with a lot of experiments depend upon the theory of laser cutting.The process parameters were analyzed in detail by theory and the result of vast experiments,such as laser gas,laser power,auxiliary gas,material thickness and so on.In the end,summarizing optimal cutting quality and the best process parameters should be reached by measuring the surface roughness of the incision.
