A new fabrication technique for the generation of optical aspherical surfaces of revolution is presented. This fabrication technique combines the characteristics of conventional loose abrasive machining with features of high-precision machining tools. A prototype of the machine tool based on this fabrication technique is currently being developed. We describe the characteristics of this method. Fabrication of aspherical ultraprecise surfaces using a tube is a line-contact method for the generation of both on- and off-axis, convex and concave, aspherical surfaces of revolution. It employs a self-correcting process and enables the use of loose-abrasive ductile grinding [Appl. Opt. 30, 2761-2777 (1991)] and subsequent bowl-feed polishing [Appl. Opt. 26, 696-703 (1987); Opt. Eng. 31, 1086-1092 (1992); Appl. Opt. 33, 89-95 (1994)] for the generation of aspherical surfaces.
提出了一种用于生成光学非球面旋转曲面的新制造技术。这种制造技术将传统的松散磨料加工特性与高精度加工工具的特性相结合。基于这种制造技术的机床原型目前正在开发中。我们描述了这种方法的特性。使用管子制造非球面超精密表面是一种线接触方法，用于生成轴上和轴外、凸面和凹面的非球面旋转曲面。它采用自校正工艺，并能够使用松散磨料延性磨削[《应用光学》30, 2761 - 2777(1991)]以及随后的碗式进给抛光[《应用光学》26, 696 - 703(1987);《光学工程》31, 1086 - 1092(1992);《应用光学》33, 89 - 95(1994)]来生成非球面表面。
