N1 - Funding information: The authors would like to thank the German Research Foundation (DFG) for their support of the Transregional Collaborative Research Centre 73 (TCRC 73) Manufacturing of Complex Functional Components with Variants by Using a New Sheet Metal Forming Process - Sheet-Bulk Metal Forming”. of the part. The realization of these elements nowadays requires additional processes such as machining. Therefore, the vision of the Transregional Collaborative Research Centre 73 funded by the German Research Foundation is to reduce the production stages by forming the functional elements by means of controlled flow of the material. The long-term goal can be clarified by the functional elements to be realized using the SBMF. Examples of these elements are combined in a symmetrical demonstrator (Fig. 2).

N2 - This contribution deals with the process-machine interaction while forming parts by sheet-bulk metal forming. The goal of this process is to form complex functional elements, such as gearing and carrier elements, by means of controlled thickening of the metal sheet. The high process forces in vertical as well as in horizontal direction to form these elements, cause displacements of the tool and press components, which lead to parts defects retroactively. This work demonstrates these challenges with regard to manufacturing of asymmetrical parts and introduces a suitable approach to represent the process-machine interaction by modelling.
