Abstract: In order to resolve the problems of machining non-axisymmetric aspheric lens, which is short of flexibility in mould grinding and needs high accuracy CNC machine center in globe diamond wheel grinding, a new parallel grinding method that utilizes common arc diamond wheel is put forward. Base on the approach calculation of machining locus, the advantages of parallel grinding that machines non-axisymmetric aspheric lens by 2.5-axis CNC machine center have been obtained. The results of grinding experiment show the new method can meet the need of grinding high accuracy non-axisymmetric aspheric lens.
