Abstract
A system for the automatic adjustment of the pressure pad holding force in accordance with the thickness of the workpiece and the forming tool stroke includes a force transducer and a displacement transducer. The force transducer is used to monitor the force between the pressure pad and the workpiece. The output of the displacement transducer is continually read as the part is being formed. The workpiece thickness and forming tool stroke are used to calculate the optimum holding force. The pressure of a fluid system is adjusted to change the holding force to the optimum value.
