METHOD AND APPARATUS FOR POLISHING OPTICAL ELEMENTS

摘要

An apparatus for controlling the machining of optical elements is disclosed. The apparatus comprises the thus measured value of radius curvature with the measured value of radius curvature of previously polished lens, means for determining curvature correcting value by comparing the thus obtained curvature variation value with a previously set allowed value of radius curvature, means for determining correcting value of machining conditions during the swinging motion based on the thus determined curvature correcting value, and means for adjusting the machining conditions in accordance with the correcting value of machining conditions.
