通过对口径Φ84mm平凸非球面透镜加工工艺的研究，提出了全口径柔性抛光结合小磨头修正抛光的试验方案。通过实验引入铣磨补偿量来抵消全口径抛光带来的面型误差，并对小磨头修正抛光比较突出的工艺参数进行单因素试验，其中包括小磨头尺寸选择，抛光压力选择。通过改变抛光盘尺寸有效减少了中频误差，优化工艺流程参数后抛光的元件面型精度（PV值）0.49μm，达到中等精度要求。总结出一套效率高，成本低，重复性好的数控研抛非球面方法，可实现中小口径非球面元件大批量快速加工。%The technology of full-diameter-flexibly-polishing and small-grinding-tools-correcting-polishing is raised by processing a flat convex aspherical lenses which has a diameter of Φ84mm.And it offsets the surface profile error through the grinding’s compensation and making the single-factor experiment to the small-grinding-tools-correct-ing-polishing’s prominent technological parameters, including the small-tools size selection, polishing pressure selection. The mid-spatial-frequency error is reduced effectively by changing the size of the polishing tools. the precision of the component’s surface profile (PV) can reach 0.49μm after optimizing the process parameter. There fore,a high efficiency a low cost and good reproducibility, numerical control aspherical lapping method is summarized. This method can real-ize that the small and medium-caliber aspherical elements are processed rapaidly in large quantity.
