Percussion drilling is a type of laser drilling operation for which optimized 5-axis trajectory planning has been developed. While percussion drilling is less advantageous in terms of local thermal loading and achievable part quality, it is used extensively in industry, due to its simplicity of automation compared to on-the-fly drilling. Thus, a TSP-style trajectory planning algorithm has been developed for percussion laser drilling. The novelty, in this case, is concurrent planning of 5-axis time-optimal point-to-point movements within the sequencing algorithm, and direct minimization of the total travel time, rather than just distance (in two Cartesian axes), as is the method for which a significant portion of TSP solvers and trajectory planners in the literature has been developed. Compared to currently applied methods, 32–36% reduction in the beam positioning time has been achieved. Also, 39–45% reduction in the peak magnitude of vibration has been realized. Limited benchmarking with the state-of-the-art TSP solvers from combinatorial mathematics, considering only 2-axis Euclidean distance as the objective function, indicates that the proposed sequencing algorithm for percussion drilling is sub-optimal by 9–12%. Thus, it can still use further improvement in future research. Nevertheless, the trajectory planners that have been developed in this paper for percussion drilling have experimentally demonstrated very promising improvements in terms of motion time and smoothness. As more advanced laser control electronics with deterministic execution and rapid synchronization capability become available, such algorithms are expected to facilitate significant production gains in laser drilling processes used in different industries.

冲击钻是一种激光钻孔操作，已针对其开发了优化的5轴轨迹规划。虽然冲击钻在局部热负荷和可达到的零件质量方面没有优势，但由于它比即时钻具有自动化简单的优点，因此在工业中得到了广泛的应用。因此，已经开发了用于冲击激光钻孔的TSP样式的轨迹规划算法。在这种情况下，新颖性在于在排序算法中同时规划5轴时间最佳点到点运动，并直接最小化总行程时间，而不仅仅是距离（沿两个笛卡尔轴）已经开发了很多方法的TSP求解器和轨迹规划器。与目前采用的方法相比，光束定位时间减少了32–36％。此外，已经实现了将振动峰值降低39–45％。仅将2轴欧氏距离作为目标函数，使用组合数学中最先进的TSP求解器进行有限的基准测试，这表明所建议的冲击钻排序算法次优达9-12％。因此，它仍然可以在未来的研究中使用进一步的改进。尽管如此，本文为冲击钻开发的轨迹规划器在实验上已经证明了在运动时间和平滑度方面非常有希望的改进。随着具有确定性执行和快速同步功能的更先进的激光控制电子设备的问世，
