光学表面加工的传统方法是用一个简单工具在尺寸大致相同的工件上转动和移动。工具与工件之间磨浆粒子的研磨作用使工具表面变成球形。假如用户要求与球形稍有偏差的形状,则需要通过改变工具的尺寸和行程特性来达到。遗憾的是,这种方法不能加工偏离球形较大的工件,也不能加工加载下显著变形的工件。在此情况下,光学元件制造商常常使用比工件小得多的工具,并把这些工具置于计算机控制之下,以提高研磨和抛光效率。在此种方法中,微机调节工件表面上工具的运动,同时根据最佳材料去除公 The traditional method of optical surface processing is to use a simple tool to rotate and move on roughly the same size of the workpiece. Grinding of the particles between the tool and the workpiece causes the surface of the tool to become spherical. If the user requires a slight deviation from the spherical shape, you need to change the tool size and stroke characteristics to achieve. Unfortunately, this method does not allow the machining of large-scale workpieces that deviate from the spherical shape and can not work with significantly deformed workpieces under load. In this case, optical component manufacturers often use tools that are much smaller than the work piece and place the tools under computer control to improve grinding and polishing efficiency. In this method, the computer adjusts the movement of the tool on the surface of the workpiece while removing the material based on the best material
