Abstract

A method and system for providing real time measurements of draw-in for closed loop control of a metal forming process including an elongated sensor (30) on one of the tools (64) positioned in the proximity of the deformation zone and adjacent to an edge of a sheet blank (60) being formed. The sensor includes coils (34)(35) disposed in a signal coupling relationship and during the forming process, a signal applied to one of the coils induces a signal in the coil, producing a response signal that varies linearly as a function of the amount of overlap between the sensor and the sheet metal blank as the sheet metal blank is drawn into the deformation zone. A feedback signal produced from the response signal is used to control a parameter of the forming process as a function of retreat of the edge of the sheet metal blank into the deformation zone.
