摘要：In a lens grinding apparatus, shape data of an eyeglass frame and layout data of an eyeglass lens for the eyeglass frame are input. Edge positions of front and rear surfaces of the eyeglass lens are measured on the basis of the input data. The position variation information of the front and rear surfaces of the lens with respect to a radius vector is input. An inclination angle of a finishing grinding wheel is stored. Edge positions after a finishing process are calculated on the basis of the measured edge positions, the input position variation information, and the inclination angle of the finishing grinding wheel. A chamfering grinding wheel for chamfering edge portions of a finish-processed eyeglass lens is controlled on the basis of the edge positions obtained by the edge position calculation. A chamfering process is easily performed, and particularly chamfering is uniformly performed.
