Abstract
A method and apparatus for forming a shape such as a cavity in a workpiece. An aperture is provided in the area in which the cavity is to be formed. Thereafter, the cavity is depressed into the metal causing the metal to flow into the area from which metal was removed by the aperture formation. If desired, after formation of the original aperture, the cavity may be partially depressed, and the aperture requalified to a circular shape. Thereafter, the cavity may be depressed into the workpiece to its final depth.
