Abstract

Grinding wheel wear has always been one of the key factors that affecting the high precision manufacturing of aspheric optical elements. With the increase of hardness and caliber of workpiece, the phenomenon of wheel wear is more serious. In this paper, the grinding wheel wear rule and the influence of surface form accuracy are discussed. Through orthogonal experience, the parameters of nonlinear regression equation about grinding ratio are determined. And the influence model of grinding wheel wear on the surface form accuracy of the workpiece is built according to the geometric relationship between the grinding wheel and the workpiece of surface. Then, the influence of workpiece caliber, the radius of grinding wheel and the arc radius of grinding wheel to the surface form accuracy are discussed. The machining range constraint by typical precision requirements is obtained, and the surface error compensation method based on the prediction of grinding wheel wear is proposed lastly.
