Abstract
An apparatus and a method for forming or polishing a concave or convex radius surface on a work-piece is described herein. The apparatus includes a carrier that is configured to support a work-piece. A substantially hollow rotatable tool, which includes a circumferential surface for either forming or polishing the radius surface, is positioned adjacent the carrier. An axis of rotation of the tool is oriented at an oblique angle with respect to a longitudinal axis of the work-piece and a longitudinal axis of the carrier. Alternatively, the longitudinal axis of the work-piece may be laterally offset from the longitudinal axis of the carrier. The apparatus further includes provisions for rotating the hollow rotatable tool for forming or polishing a radius surface on the surface of the work-piece.
