Abstract

A buffing fixture and structure for supporting large and thin metal skins during a finishing operation. The structure includes a plurality of individual form fixtures, at least one trunnion table mounted for rotation along a horizontally disposed axis, and a motor for causing the rotation of the trunnion table. Each of the form fixtures is comprised of a frame having at least one brace which extends outwardly from the frame, a form shell mounted to the frame such that the interior surface is in contact with a longitudinal edge of the brace, and a layer of foam disposed substantially along the entire interior surface of the form shell in order to support the surface area of the form shell. The form shell has a three dimensional shape which follows the three dimensional shape of the metal skin to be finished. A set of straps are also provided in order to removably secure and register the position of the metal skin to the form shell, such that the metal skin lies flush against the exterior surface of the form shell.
