There are a number of variables which can seriously affect the sheet metal forming process. By determining the process fluctuations an improved production process can finally be achieved. To do this, monitored or closed loop controlled processes can be an important tool for the reduction of defects, reduction of rework and a better quality of final products. The Fraunhofer Institute for Machine Tools and Forming Technology IWU in Chemnitz investigated typical process variables like flange movement as a basis of control systems. Different kinds of non-contact sensors were successfully tested. A multi-point cushion or tool integrated piezo-elements in connection with torsionelastic tools were used as reacting systems. In one application process monitoring with one or more sensors for supporting quality control or same system with an add-on for early error recognition and automatically recommended corrected measures was used. Finally, fully controlled loop systems based on intelligent algorithms were developed.
