| 摘 要： | 光学加工中边缘问题很难处理，数控加工也是如此。计算机数控能动盘光学加工技术具有高加工效率和抑制中高频能力，而小磨头光学加工技术则有很强的局部误差修正能力。介绍了将这两种数控光学加工技术处理大口径非球面镜面边缘区域误差修正的加工模型算法，并进一步结合二者特点提出大口径边缘加工组合工艺方法。首先使用能动盘加工技术初步磨削工件边缘，接着用小磨头技术进行局部修磨，再使用能动磨盘技术进行表面平滑。这种加工策略能够有效地实现工件边缘区域的定量磨削去除加工。对圆对称工件的细磨试验证明了这一点。

| Abstract: | One of the most difficult problems in optical fabrication is how to figure near the workpiece edge.The active-lap is able to remove the middle and high frequency errors by smoothing,and the small tool is adapt for removal of the local error.The approach to deal with edge removal profile by using the active-lap and small-tool is introduced.And a compositive way is developed while the tool is hanging over the workpiece edge.The edge removal profile can be improved by suitably aligning the active-lap and the small tool technologies.The manufacturing examination shows good evidence of the effects of the approach. |
