Abstract
Removal function models play an important role in the computer simulation and the practical Computer Controlled Optical Surfacing. This paper presents a novel general model, which can simulate the removal function of a grinding (polishing) tool with any configuration, as long as the tool runs in dual rotation mode. The removal functions of a dual rotation tool with a single pad or with two pads were calculated by this general model and by the existing single pad and two-pad removal function models, respectively and the simulation results coincide with each other. The grinding & polishing experiments also verify this general model. A set of optimized seven-pad flexible grinding (polishing) tool was developed according to this model. A template function model, which simplified the two-dimension parallel circles tracks programming problem into a one-dimension problem was derived from this model. A Φ300 mm, F5.9 focus lens, with 46 μm aspheric degree was successfully fabricated according to the programming results after 8 hours 43 minutes fine grinding & 15 hours polishing.
