Paper Abstract

In the manufacturing process of aspheric glass lenses, the polishing step plays a key role with respect to the final quality of the lens as well as to the manufacturing costs. Due to the changing radius of curvature sub aperture tools are used for polishing aspherical lens elements. Even with small tools the changing radius has a significant influence to the wear function [1] [2]. This paper describes a method to calculate the removal based only on the surface shape and the material parameters of the tool. The described method can be used for any kind of surface, e.g. for freeform shapes.
