Abstract
A metal workpiece, such as a gear blank, is forged in a press. The workpiece is first heated and then placed in a working chamber above the press. Force is applied against opposite sides of the workpiece to press the metal of the workpiece outwardly against a sidewall formed by a ring die and inwardly against a side surface of a removable center section. After the workpiece has been shaped, the workpiece and the center section are removed from the working chamber of the press with the center section firmly gripped by the workpiece. The workpiece is then allowed to cool and the center section is separated from the workpiece.
