The major objective of the work was to generate a holistic understanding of manufacturing thin-walled functional components out of sheet metal by Sheet-Bulk Metal Forming in order to increase the technical opportunities of metal forming processes. In this context, the potential of single-stage process strategies combining conventional sheet and bulk forming processes was analysed. Within the framework of these investigations it was worked out in detail for the first time that the combination of deep drawing and upsetting is suitable for the manufacture of various functional components out of thin sheets. The essential functional correlation between tool design, process parameters and component properties has been identified. In addition, it was shown that component quality and resource efficiency can be improved by the suitable selection of technical parameters and by the application of innovative process strategies using tailored blanks and tailored surfaces.
