Stamping processes are routinely validated and optimized using simulation tools. Process optimization, carried out manually or automatically, establishes a single set of conditions capable of producing a good part, without any consideration of the robustness of the stamping process. This paper presents a new approach to virtual validation of stamping processes that simultaneously, and in a natural fashion, also provides valuable feedback on process robustness over the entire production lifetime of a given part. Uncontrollable variabilities in material and process conditions — as they actually occur under production conditions — are taken into account in a true “simulation” of stamping processes, providing quantitative measures of robustness as well as a clear picture of sensitive dependencies between critical panel quality attributes and controllable process conditions. The latter is important to identifying meaningful countermeasure options available to influence and improve production quality, and to minimize overall production cost.
