在非球面透镜的加工中,必须使加工面的对称轴一致,因此工具的工作端面必须沿着回转表面的子午面运动。对于这一点,可以由各种方法来完成。若按工具与工件运动的控制方法及动作原理来区分,常采用的有数字控制法、电子计算机控制法、凸轮仿形法、连杆机构法、利用玻璃弹性变形加工法、样板法及修整磨盘加工法等。随着数控技术的发展,非球面零件的数控磨削装置已出现不少。特别适用于小批量、多品种生产及模具或样板的制造。美国的A.Cox于1961年发表的小直径非球面磨研、抛光机,1969年日本的中野智允等人发表的大型施密特校正板抛光机,都属于这一类机 In the machining of aspheric lenses, the symmetry axes of the working surfaces must be made uniform so that the working end surfaces of the tools must move along the meridional surface of the turning surfaces. This can be done in a variety of ways. If the tool and workpiece movement according to the control method and action principle to distinguish, often used are digital control method, computer control method, cam profiling method, linkage method, the use of glass elastic deformation method, the sample method and dressing disc Processing methods. With the development of numerical control technology, a number of non-spherical CNC grinding equipment has emerged. Particularly suitable for small batch, multi-species production and mold or model of manufacturing. A.Cox in the United States in 1961 published in small diameter aspheric grinding polishing machine, 1969 Japan’s Nakano Chi Yun and others published large Schmidt correction plate polishing machine, belong to this category
