摘要
为了提高钣金激光切割的效率和质量,提出了一种新的轮廓加工点的选取方法,即除两点间距离外,又考虑了轮廓的加工顺序及位置分布对加工点选取的影响。首先使用改进萤火虫算法优化轮廓的加工顺序,然后结合轮廓的中心点位置经局部搜索优化得到各轮廓的最优加工点,最后构成完整的加工路径。介绍了算法的原理及实现,通过实验仿真较遗传算法优化轮廓端点的方式路径缩短了2.6%,较采用最近邻法则的方式路径缩短了5.7%,明显实现了进一步优化。
In order to improve the efficiency and quality of laser cutting of sheet metal,a new selection method of contour processing points is proposed in this paper.Besides the distance between two points,this method also considers the influence of the processing sequence and position distribution of contour on the selection of processing points.First,the improved firefly algorithm was adopted to optimize the processing sequence of contour.Then,combined with the location of the central point of contours,the optimal processing points of contours were obtained by local search.Finally,a complete processing path was formed.In addition,the principle and realization of the algorithm are introduced in this paper.The simulation results show that the path was shortened by 2.6%compared with genetic algorithm,and was shortened by 5.7%compared with the nearest neighbor rule,which obviously achieved further optimization.
