Abstract

Microlens arrays have been widely used in industry and extensively researched in academia over the years. Lens arrays machined by slow and fast tool servo technologies commonly suffer from vibration marks near lens edges, which undermine surface finish and from accuracy. The vibration marks are caused by the machine tool's nonlinear response to abnormally large local tool path accelerations at lens edges. In this study, a globally smooth tool path reconstruction method based on frame line guided cubic spline interpolation is proposed. The incorporation of globally continuous frame lines is demonstrated to significantly improve both tangential and radial tool path smoothness. Comparative theoretical analysis and experimental investigation are conducted together with direct strategy and tangentially smooth strategy. Experimental results show significant suppression in vibration marks, a 43.8 % decrease in surface roughness Sa, and a 63.0 % decrease in form error PV compared to the direct strategy. And equal results are acquired using the proposed method with twice the efficiency of the direct method. Moreover, the nonuniformity of surface topography in a single lens resulting from the periodic cutting-in motions is also observed, explained and effectively reduced in this study.

用于超精密金刚石车削微透镜阵列的全局平滑刀具路径重建方法
多年来,微透镜阵列已广泛应用于工业领域,并在学术界得到了广泛研究。采用慢速和快速刀具伺服技术加工的透镜阵列通常会在透镜边缘附近出现振痕,从而影响表面光洁度和精度。振痕是由于机床对透镜边缘异常大的局部刀具路径加速度的非线性响应造成的。本研究提出了一种基于帧线引导的三次样条插值的全局平滑刀具路径重建方法。事实证明,全局连续帧线的加入能显著改善切向和径向刀具路径的平滑度。理论分析和实验研究与直接策略和切向平滑策略进行了比较。实验结果表明,与直接策略相比,振动痕迹明显减少,表面粗糙度 Sa 下降了 43.8%,形状误差 PV 下降了 63.0%。使用建议的方法可以获得相同的结果,其效率是直接方法的两倍。此外,本研究还观察、解释并有效减少了周期性切入运动导致的单个透镜表面形貌不均匀性。
