激光表面毛化技术在制造平面表面微结构方面具有广阔的应用前景，但利用激光烧蚀技术在大曲率的微小零件上实现微米级的非平面表面的连续刻划是一项具有挑战性的工作。在本工作中，我们论证了所提出的多轴激光铣削在直径25 mm的球形不锈钢连续成形中的可行性，基于同时调整激光-表面相互作用点的位置和姿态的策略，以保证激光光束与烧蚀表面法线的恒定重合，获得了高一致性和高精度的球形不锈钢。具体地说，设计了一种用于控制工件高自由度运动的小型化五轴平台，并将其与工作在1064 nm的固定纳秒脉冲激光集成在一起。基于预定平面图案在球面上的投影和变换，推导出激光与表面相互作用点的精确路径。同时，建立了嵌入插补算法的多轴激光铣削虚拟样机，为后续的激光铣削实验生成NC代码。此外，还进行了球面激光加工参数的采样。最后，利用所提出的多轴激光铣削方法在球面上连续形成复杂的图形，随后的表征表明所制造的图形具有长范围的均匀性和局部的高精度。为大曲率微小零件非平面表面的连续激光毛化提供了一种可行的方法。
While laser surface texturing is promising for the fabrication of planar surface microstructures, the continuously patterning with micrometer accuracy of non-planar surface on miniature parts with large curvature by laser ablation is challenging. In the present work, we demonstrate the feasibility of applying the proposed multi-axis laser milling in continuous patterning of 25 mm diameter spherical stainless steel with high uniformity and precision, based on a strategy of simultaneously adjusting the position and the posture of laser-surface interaction point for enabling the constant coincidence of laser beam with ablated surface normal. Specifically, a miniaturized five-axis platform for controlling workpiece motion with high degree-of-freedom is designed and integrated with a fixed nanosecond pulsed laser beam operating at 1064 nm. The precise path of laser-surface interaction point is derived based on the projection and transformation of pre-determined planar pattern on spherical surface. Meanwhile, a virtual prototype of the multi-axis laser milling with embedded interpolation algorithm is established, which enables the generation of NC codes for subsequent laser milling experiments. Furthermore, the sampling of laser processing parameters particularly for spherical surface is carried out. Finally, complex patterns are continuously structured on the spherical surface by employing the proposed multi-axis laser milling method, and subsequent characterization demonstrates both long range uniformity and local high accuracy of the fabricated patterns. Current work provides a feasible method for the continuous laser surface texturing of non-planar surfaces for miniature parts with large curvature.
