电弧熔丝增材制造复合填充路径规划算法

合理的路径规划可以提高电弧熔丝增材制造成形零件的表面质量和强度。针对电弧熔丝增材制造的特点,将多种增材制造路径规划算法相结合,提出了一种复合路径规划算法,实现了单空洞截面的填充,并进一步讨论了其他类型截面的路径规划方法。在填充截面过程中,内外表面采用轮廓偏置路径填充,保证了零件的表面质量;零件内部采用改进的扫描线算法进行填充,减少了空行程,提高了成形效率。实验验证了本文算法填充复杂截面轮廓的可行性。

Composite Filling Path Planning Algorithm for Wire and ARC Additive Manufacturing

Reasonable path planning can improve the surface quality and strength of the formed parts of Wire and Arc additive manufacturing. Aiming at the characteristics of arc fuse to add material manufacturing, varieties of material manufacturing path planning algorithms are combined, and a compound path planning algorithm is proposed. The single hollow section fill is realized, and the other types of cross section of path planning method is further discussed. In the process of filling section, the inner and outer surface is filled with the contour offset path to ensure the surface quality of the parts. The improved scanning line algorithm is used to fill the parts, reduce the empty stroke and improve the forming efficiency. The complex section profile can be filled and the feasibility of the algorithm is verified by experiments.
