摘　　要：针对铝合金激光切割工艺参数优化问题,对5052铝合金进行了激光切割试验研究,根据不同的激光功率、辅助气压、运行速度参数对激光切割质量的影响,建立了三因素正交试验方案,选用0.3 mm、0.5 mm厚的薄板铝合金进行了激光切割,以1 MPa和1.5 MPa的氩气,选用10%、20%和30%的切割运行速度,分别采用1200 W和1350 W的激光功率进行切割。分别用光切测试仪和显微镜观测了粗糙度和挂渣长度两个质量参数,进行数据分析,确定了0.3 mm、0.5 mm薄铝合金板的最佳激光切割工艺路线,为铝合金激光切割薄板提供技术参考。Aiming at the optimization of laser cutting process parameters for aluminum alloy,laser cutting experiments were conducted on 5052 aluminum alloy.This article establishes a three factor orthogonal experimental plan based on the influence of different laser power,auxiliary air pressure,and operating speed parameters on laser cutting quality.A 0.3 mm and 0.5 mm thick thin aluminum alloy was selected for laser cutting,and 10%,20%,and 30%orthogonal operating speeds were designed with 1 MPa and 1.5 MPa argon gas,and laser power of 1200 W and 1350 W,respectively.Two quality parameters,roughness and slag length,were observed by a light cutting tester and microscope,and data analysis was conducted to determine the optimal laser cutting process route for 0.3 mm and 0.5 mm thin aluminum plate,providing technical reference for laser cutting of aluminum alloy thin plates.
