According to the requirement of high precision non-axisymmetric aspheric surface machining, and analyzing the locus planning limitation of traditional aspheric machining, a set of machining locus planning methods has been put forward to meet the requirement of non-axisymmetric aspheric machining. The method can minish the average and maximum value of residual error in divided area. Experiment result shows that the new machining method can fit ideal locus more, can minish machining error and improve machining accuracy more. It can get stable accuracy when the machining parameters are fixed.
