摘　　要：曲面微透镜阵列由多个子眼组成,加工路径连续,但各子眼之间的表面不连续,加工轨迹规划困难,容易造成加工形状不理想,粗糙度过大的问题。针对此类问题,对环形排布的曲面微透镜阵列结构进行了研究,提出了新的曲面微透镜阵列加工方法,采用区域划分法和等角度离散方法进行轨迹规划,考虑了刀尖圆弧半径对加工精度的影响并采用近似Z向刀尖补偿法对刀尖圆弧半径进行了补偿,利用MATLAB软件进行了曲面微透镜阵列的加工轨迹仿真及形貌模拟,最后利用慢刀伺服加工方法进行了切削加工试验验证。试验结果表明,所提出的加工方案能够实现纳米级表面粗糙度要求的曲面微透镜阵列加工。The curved microlens array is composed of multiple sub eyes,with continuous processing paths.However,the surface between each sub eye is discontinuous,making it difficult to plan the processing trajectory,which can easily lead to problems such as suboptimal processing shape and excessive roughness.To solve this problem,the structure of annularly arranged curved surface microlens array is studied,and a new machining method of curved surface microlens array is proposed.The area division method and the equal-angle discrete method are used for trajectory planning.The influence of radius of tool point arc on machining accuracy is considered,and the approximate Z-direction tool point compensation method is used to compensate the radius of tool point arc,The machining path and morphology of curved surface microlens array are simulated by MATLAB software.Finally,the machining process is verified by the slow tool servo machining method.The test results show that the proposed processing scheme can realize the machining of curved surface microlens array required by nano-scale surface roughness.
