摘要
为了实时控制激光焦点与辅助气体中轴线处于不同轴状态,采用结合电磁和永磁优点的磁力驱动平台对激光焦点和辅助气体中轴线之间的位置关系进行实时控制。激光加工复杂图形过程中加工的路径是不规则的,为了提高传统激光切割的质量和切割速度,运用模糊PID的控制算法对平台回转响应特性进行分析。仿真和实验结果表明,仿真的转角响应时间为0.15 s,实验的转角响应时间为1.7 s。磁力驱动平台在模糊PID的控制下可以保持稳定并具有较好的响应特性。
In order to control the laser focus and the auxiliary gas central axis in different axial states in real time, a magnetic drive platform, combining the advantages of electromagnetic and permanent magnets, is used to real-time control the positional relationship between the laser focus and the auxiliary gas central axis. The machining path is irregular in laser processing of complex graphics. In order to improve the quality and cutting speed of traditional laser cutting, the platform response characteristics is analyzed by the control algorithm of fuzzy PID. The simulation and experimental results show that, the simulated corner response time is 0.15 s, and the experimental corner response time is 1.7 s. The magnetic drive platform can be good stability and response characteristics under the control of fuzzy PID.
