Abstract
Machining apparatus comprising a major C-frame for carrying an upper tooling head and a rotatable minor C-frame for carrying a lower tooling head cantileverly supported away from a body portion of the minor C-frame to provide a throat for receiving a workpiece edge portion while another workpiece portion is positioned between the heads for machining, the minor C-frame being rotated to provide clearance for the workpiece. As a result, a substantially semi-cylindrical workpiece may be machined over its surface without refixturing thereof.
