Abstract

Aspherical parts are the hot issues in the field of optics. With the rapid development of science and technology, optical aspherical surface has become an indispensable component in optical system because of its unique structure, the application and development of aspherical surface are restricted by the residual annular ripple error. In this paper, the main causes of the residual toroidal corrugation error on aspheric surface are analyzed in detail, and the causes of toroidal corrugation are demonstrated and analyzed from five key points, a new method of aspherical NC forming is proposed, and the concrete steps of the new principle of aspherical forming are analyzed.
