【Abstract】 The reasons and function mechanism of aspheric surface figure error in middle and high frequencies are analyzed.Considering the influences of cutting tool,cutting parameters,machining path,cutting condition,measuring method,and machining environment etc.,the optimal selection rules and control strategy are put forward.To decrease the cutting error,the compensation principle and programming design method are also proposed.By testing the programming compensation in the numerical control machine tool,the results show that surface figure error is effectively controlled.更多还原
