Abstract A new scan path strategy is presented to reduce the duration of laser processing of geometries consisting of scattered, unconnected processing areas of a small size. We refer to these as fragmented geometries. The novelty of this strategy is to first identify optimized parallel scan lines for the overall shape using the Radon transform, which provides information about the most productive scan line orientations. The lines are then chopped into mark and jump vectors exploiting fast laser power modulation to precisely process the fragmented structure. An experimental study was conducted with a galvanometer scanner and a set of exemplary geometries comparing the proposed strategy with conventional raster scanning and a fill strategy. The results show a reduction in processing time with the new algorithm of up to 57% depending on the geometry. This finding indicates, that the new strategy is a promising approach for improvement of productivity for areal laser processing applications.

用于碎片几何形状激光加工的扫描路径策略

摘要 提出了一种新的扫描路径策略，以减少由分散的、不相连的小尺寸加工区域组成的几何形状的激光加工持续时间。我们将这些称为碎片几何。这种策略的新颖之处在于首先使用氡变换确定整体形状的优化平行扫描线，它提供有关最高效扫描线方向的信息。然后利用快速激光功率调制将这些线切割成标记和跳跃矢量，以精确处理碎片化的结构。使用振镜扫描仪和一组示例性几何结构进行了实验研究，将所提出的策略与传统光栅扫描和填充策略进行了比较。结果表明，根据几何形状，使用新算法最多可将处理时间减少 57%。
