Abstract

A novel ultra-precision turning method is proposed to machine the aspheric surface. Based on this novel method, the aspheric surface is regarded to be divided into two superimposed parts, base sphere and radial asphericity. The base sphere is machined through the revolution of tool pendulum shaft, while the radial asphericity is processed through the feed movement of micro-displacement mechanism. The machining principle of base sphere and the calculation of radial asphericity are analyzed theoretically. In the end, experiments are carried out on an ultra-precision lathe, and the measured result shows that the P-V value is about 0.27μm.
