Abstract
A method and an apparatus for shaping an edge at a juncture of two adjoining surfaces of a part. A first surface and a second surface of the part are abraded by contacting a polishing surface of a polishing wheel to the first surface and to the second surface. The polishing surface spins in opposite rotational directions about an axis parallel to the edge when contacting the first and second surfaces respectively. The polishing surface moves at different translational speeds and the polishing wheel spins at different rotational speeds along straight segments and along curved segments of the edge. The shaped edge has a visually smooth and geometrically uniform appearance.
