  • Patent number: 7047788
    Abstract: A method for providing improved thickness control of a workpiece formed by impact forming. An impact forming device includes an upper die and a lower die that is configured and disposed for receiving the heated workpiece. The upper die is operatively connected to a ram for directing the upper die into a controlled impact with the lower die while the workpiece is positioned between the upper die and the lower die. This controlled impact forms the workpiece. A precise relationship is determined between a finished thickness of the workpiece and a time duration that the workpiece is in contact with the lower die prior to impact with the upper die to achieve the particular workpiece thickness. Once the workpiece is placed on the lower die, the ram is actuated to effect the controlled impact of the upper and the lower die in response to the precise relationship.
