基于改进的Zig-zag与Contour-parallel算法的激光打标技术

Research on Laser Marking Technology Based on lmproved Zig-zag and Contour-parallel Algorithms

激光打标需要对图案进行路径填充,选用算法的优劣直接影响到填充的质量和打标的效率,提出了Zig-zag算法以及Contour-parallel算法的优化算法。对扰动的大小、曲线平滑程度、曲线间隔平滑程度这三个方面分别定义了一个计算公式,然后进行加和得到最终的优化函数,而为了制定曲线优化的目标函数,我们又通过基于曲率的采样方式来离散化输入的曲线。在不同的图案上分别进行两种算法的优化算法的填充实验,相同的图案设置相同的线间距和边距参数,最后发现在间距参数为1/10mm级及以上时,曲线平滑度可以得到显著的提升,且Zig-zag算法填充速度更快。提出了一种激光打标算法的优化方案,这种优化方案是具有建设性的而不是惯例,今后将这两种算法结合起来,使它既具有连续性、平滑度同时又不影响打标速度。

Laser marking needs to fill the pattern path,and the quality of the selected algorithm directly affects the filling quality and marking efficiency.In this paper,the optimization algorithms of Zig-Zag algorithm and Contour-Parallel algorithm are proposed.The filling experiments of the optimized algorithms of the two algorithms are carried out on different patterns,and the same pattern was set with the same line spacing and margin parameters.Finally,it was found that when the spacing parameters are 1/10mm or above,the smoothness of the curve could be significantly improved,and the filling speed of the Zig-Zag algorithm was faster.This paper proposes an optimization scheme of laser marking algorithm.This optimization scheme is constructive rather than routine.In the future,the author want to combine these two algorithms to make it have continuity,smoothness and not affect the marking speed.
