Abstract

A universal polishing tool comprises a rigid cup having a circular rim to which is attached a relatively thin resilient polishing pad. In accordance with a method for using the tool, the tool is rotated about the axis of a support shaft causing the resilient polishing pad to move with respect to the surface which is being polished. The universal polishing tool is dynamically positioned as a function of time with respect to the surface being polished. The orientation and position as a function of time are determined by a control algorithm according to the geometry of the tool and the particular surface being polished and are controlled by means of a controllable positioning device. In the case of a spherical surface or a rotationally symmetric aspheric surface, the lens is rotated about its axis of symmetry during the polishing operation. In the case of a toric surface, the lens is oscillated about an axis which is normal to its center.
