The scope of the project is the analysis of the transferability of the investigated methodology for the versatility of a tumbling self-piercing riveting process within the subproject "Versatile joining with a fastener" in the context of the transregional collaborative research center TRR (SFB/TRR) "Method development for mechanical joinability in versatile process chains" under industrial conditions. Within this context, this versatility should be expanded by target-oriented adaption of relevant process parameters. Central aim within this research project is the transfer of fundamental results for a defined formation of geometrical joint characteristics, like for example undercuts from the tumbling self-piercing riveting process to a novel joining by orbital forming process. Within the SFB/TRR, scientific methods for the versatility of mechanical joining processes and process chains are investigated fundamentally. These results should be applied and transferred onto industrial relevant questions regarding the joining process as well as the component design. The established joining process of self-piercing riveting is combined with an orbital forming process and investigated fundamentally in the scope of the subproject and the technological potential for an increased versatility is evaluated. In this context, the tumbling kinematic, the tumbling angle as well as the chosen joining partners could be identified as significant influence on the forming of undercuts and the rivet head end position and in consequence on the joint quality. Nevertheless, limiting factors prevent a possible industrial application. Due to the use of an additional fastener, the joining direction is a considerable issue besides the increased handling effort. Furthermore, parts with a joint in the sheet metal plane cannot be manufactured. Therefore, the fundamental findings on the geometrical joint formation within the tumbling self-piercing riveting process should be transferred in close cooperation with the involved partners SRAM Deutschland GmbH and C.D. Wälzholz GmbH & Co. KG onto a new joining technique, exclusively consisting of an orbital forming step without additional fastener, under industrial aspects. Besides the use of industrial relevant material classes, a fundamental process understanding of the novel, versatile joining process regarding the occurring interdependencies should be established and a possible later application should be evaluated. By a defined adaption of relevant process parameters, identified in this project, the foundation for a possible application of this new versatile process should be placed. Both partners participate with specific know-how on semi-finished products, material, application, requirements and the evaluation of quality and consequently contributing significantly to the success of the transfer project.

KG 密切合作，将滚压自冲铆接工艺中几何接头形成的基本发现转移到一种新的连接技术上，该技术专门包括轨道成型步骤。无需额外的紧固件，在工业方面，除了使用工业相关材料类别外，还应建立对有关发生的相互依赖性的新颖、多功能连接过程的基本过程理解，并应在以后进行可能的应用。通过对本项目中确定的相关工艺参数进行明确的调整，应该为这种新的多功能工艺的可能应用奠定基础，双方都拥有半成品、材料、应用的具体专业知识。要求和质量评估，从而对转让项目的成功做出重大贡献。
