Abstract
A system and apparatus is disclosed for controlling a restraining force applied to a panel. The apparatus includes a die, a binder supporting the panel against the die, and a punch used to draw the panel into the die. A restraining element is disposed on one of the die and the binder that engages a surface of the panel and applies a restraining force onto the panel. A strain gauge is disposed inside at least one of the die and the binder that engages a surface of the panel to measure the restraining force applied to the panel. The level of restraining force applied by the restraining element onto the panel is controlled based upon the restraining force measured by the strain gauge.
