ABSTRACT:
An apparatus and method for performing conic sectional operations on a workpiece is disclosed. The apparatus includes a conic surface generator which traces the surface of a cone and a cutting plane generator which traces a plane so that the plane intersects the surface of the cone. The conic surface and the cutting plane generator are connected by a conic section follower which traces the intersection of the cone and the plane. The apparatus also includes a working interface for working on a workpiece and connecting means for connecting the working interface to the conic section follower so that the working surface traces a conic section equivalent to that generated by the intersection of the cone and plane.
A center of curvature guide accurately positions the working interface to provide the capability of substantially single point contact cutting and polishing.
