摘　　要：为提升激光切割的加工质量评价,提出一种激光切割高频动态复合运动轨迹规划与控制方法。首先,设计激光切割光学系统,实现激光焦点光斑在三维空间内的高频动态运动;然后,探讨激光焦点光斑不同维度的运动轨迹规划方法;接着,提出激光焦点光斑高频动态运动轨迹规划方法,并设计相应的激光切割驱动控制系统;最后,将该文方法与静态表面质量优先切割方法、静态最快切割方法进行钢板激光切割试验测试。试验测试结果表明,该文方法的切割速度为1 m/min、挂渣尺寸为0.9 mm、表面粗糙度为0.09 mm,其切割加工质量评价参数优于以上两种方法。To improve the processing quality evaluation of laser cutting,a high-frequency dynamic composite motion trajectory planning and control method for laser cutting is proposed.Firstly,design a laser cutting optical system to achieve high-frequency dynamic motion of the laser focal spot in three-dimensional space;Then,explore the methods for planning the motion trajectories of laser focal spots in different dimensions;Next,a high-frequency dynamic motion trajectory planning method for laser focal spot is proposed,and a corresponding laser cutting drive control system is designed;Finally,the method proposed in this article will be tested in steel plate laser cutting experiments with the static surface quality priority cutting method and the static fastest cutting method.The experimental test results show that the cutting speed of the method proposed in this paper is 1 m/min,the slag hanging size is 0.9 mm,and the surface roughness is O.09 mm.Its cuting and processing quality evaluation indicators are superior to the above two methods.
