大家知道,采用型小系列机床加工光学零件的非球面,其方法是用小刀具(与毛坯尺寸相比)连续加工原有的表面区带。“按区带加工非球面”,即根据机床运动学(参考文献1),靠凸轮使刀具在非球面上移动。经过长期使用上述机床表明:加工比较小的非球面(～10……30μm)时,完全可以保证非常满意的加工精度,若制造零件的非球面度为50……100μm或更大时,则加工精度难以保障。 We all know that the use of small series of machine tools processing of optical components of the aspheric surface, the method is to use small tools (compared with the blank size) continuous processing of the original surface zone. “Machining Aspheres by Zone”, ie according to machine kinematics (Reference 1), the cam moves the tool on the aspherical surface. After long-term use of these machines, it has been shown that machining of very small aspheric surfaces (~ 10 ... 30 μm) guarantees very satisfactory machining accuracy and, if the asphericity of the manufactured part is 50 ... 100 μm or more, Accuracy is difficult to protect.
