摘要: 为了使平面阵列激光微造型方法应用于工程技术领域,基于"单脉冲同点间隔多次"激光微造型新工艺,对平面阵列的加工方法进行了深入的分析研究,给出一种全新的扫描策略,对已有的加工方案进行了路径优化。由于采用该扫描策略进行"单脉冲同点间隔多次"激光微造型时,要求激光头对每行加工初始点进行精确定位,基于此,对工作台的定位问题进行了分析研究,给出了工作台精确定位流程图,并对该扫描策略的编程实现过程进行了分析研究,给出了路径优化后平面阵列加工过程流程图。结果表明,该扫描策略满足既定的"单脉冲同点间隔多次"激光微造型新工艺的加工要求,且能获得较好的微观形貌和表面质量。Abstract: In order to apply laser micro-forming planar array in engineering,the processing process of planar array was studied based on a novel laser surface texturing technology,so-called "single pulse one time,repeating at intervals".A new scanning strategy was provided to optimize the path of the old processing method.Because high positioning accuracy was demanded for the starting processing point when the new scanning strategy was applied,the location problem of the workbench was studied and the accurate positioning flow chart was provided.Finally,the programming method of the new scanning strategy was studied,and the processing flow chart was given.The results show that the scanning strategy meets the requirements of the novel processing process and better micro-morphology and surface quality can be obtained.
