摘　　要：激光器传播出来的激光模式呈现线性偏振形式,导致并联机床激光切割轨迹发生变化,从而影响切割效果和时间,为此提出并设计了基于参数优化的并联机床激光切割系统。激光器、控制面板和伺服驱动器组成系统的硬件结构;在设计系统硬件基础上,优化激光器参数,将线性偏振形式转换为圆偏振形式,使激光束的实际光束路径与激光切割轨迹保持一致;优化切割线段,获取距该直线最近的现实点以逼近该直线,令切割线段达到最优状态,通过硬件设计和软件设计完成并联机床激光切割系统设计。实验结果表明,该系统提高了并联机床激光切割精度,具有较好的切割效果,并缩短了切割时间,为工业自动化奠定了基础。Due to the linear polarization of the laser mode transmitted by the laser,the laser cutting path of PMT changes,which affects the cutting effect and time.Therefore,a PMT laser cutting system based on parameter optimization is proposed and designed.The hardware structure of the system is composed of a laser,control panel and servo driver.Based on the system’s hardware design,the laser parameters are optimized,and the linear polarization form is converted into circular polarization form so that the laser beam’s actual beam path is consistent with the laser cutting path.The cutting line segment is optimized,and the nearest real point is obtained to approach the line so that the cutting line segment reaches In the optimal state,the laser cutting system of PMT is designed by hardware design and software design.The experimental results show that the system improves the laser cutting accuracy of PMT,has a better cutting effect and shortens the cutting time,laying a foundation for industrial automation.
