Planning and Control of Sheet Metal Forming Processes using LS-OPT

Although control parameters of the stamping process are kept constant, remarkable variations in the quality of the stamped parts can be observed during the fabrication of car body parts. This is due to random variations in the material properties as well as instabilities in the stamping process itself. The present paper about metamodel based procedures used for planning and controlling sheet metal forming processes aims to show how results from stochastic simulations [7] and empirical knowledge about tryout, can be combined in order to develop a progressive process control of the stamping process that helps to prevent scrap production. This implies the layout of sensors and actuators in mechatronic deep drawing tools. The experimental validation on stamped parts shows the capability of the outlined method.
