The Study On Predicting Thetechnology Of Job Precision For Precise Equipment Processing Part'Precision

This paper mainly aim at the demand of optical system for heavy caliber non-spherical surface optical element, research non-spherical surface grinding machine of high precision and efficiency, use precision analysis and predicted theory and method, distribute errors to main parts of the machine, in this way to complete the precise prediction of the jobs. The result provides technical supports to optimize cutting parameters, increase efficiency and machining precision, give helps to process engineers to examine technology edit and numerical control program, exploit function and efficiency of the machine, decrease production prepare time and manufacturing cost obviously. So the results of this paper have important theoretical significance to precision non spherical surface machining and interrelated technology in our nation, have practical significance to manufacturing engineering and competition in market. This paper solve the problems mainly at :1. The research of non-spherical surface elements machining trace. The formation of non-spherical surface elements machining trace;2. Surface error on-line measurement, data processing non-spherical work piece machining error mathematical model;...
