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.

摘要： A holding device for holding an optical element to be ground is arranged such that pressure applied to a receiving face of the optical element on the holder base is made different in the radial direction in order to eliminate deformation, positional deviation or inclination of the optical element due to grinding resistances during grinding or due to high-pressure grinding. An elastic member is employed as an elastic member, or a receiving member capable of absorbing the positional deviation, the inclination, or the like of the optical element during grinding thereof is used.

摘要： A method of grinding a lens and an apparatus therefor during dependent machining in which an electrically conductive grinding tool which rotates and a workpiece slide in close contact with each other on the work surface of the electrically conductive grinding tool. An anode is applied to the electrically conductive grinding tool, whereas a cathode is applied to an electrode which does not move together with the workpiece, while a fixed distance is maintained between the work surface of the electrically conductive grinding tool and the electrode. Grinding is thus performed with the aid of a weakly charged coolant fed between the electrically conductive grinding tool and the cathode.
