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.

该项目的范围是分析研究的方法的可传递性，以在跨区域协作研究中心TRR（SFB/TRR）的背景下“多功能与紧固件”下翻滚的自我启动骑行过程的多功能性“多功能连接”。在这种情况下，应通过相关过程参数的针对目标的适应来扩展这种多功能性。该研究项目中的主要目标是转移了基本结果，以定义几何联合特征的形成，例如，从翻滚的自我启动骑行过程到轨道形成过程的新颖加入。在SFB/TRR中，对机械连接过程和过程链的多功能性的科学方法进行了基本研究。这些结果应应用于有关加入过程以及组件设计的工业相关问题。建立的自我启动骑行过程与轨道形成过程相结合，并从根本上进行了范围的研究，并评估了增加多功能性的技术潜力。在这种情况下，可以将翻滚运动学，翻滚角度以及所选的连接伙伴识别为对底切的形成和铆钉头端位置的显着影响，并因此对关节质量产生了影响。然而，限制因素阻止了可能的工业应用。由于使用了额外的紧固件，除了增加处理工作之外，连接方向是一个相当大的问题。此外，无法制造金属平面中有关节的零件。因此，应与相关合作伙伴SRAM Deutschland GmbH和C.D进行密切合作，在翻滚自我骑行过程中的几何联合形成的基本发现。 WälzholzGmbH＆Co。KG进入了一种新的连接技术，该技术仅由轨道形成步骤组成，而没有其他紧固件，在工业方面。除了使用工业相关的材料类外，还应建立对新事件的多功能联合过程的基本过程理解，并应建立相互依存关系，并应评估可能的以后应用。通过在本项目中确定的相关过程参数的定义改编，应放置可能应用此新的多功能过程的基础。两个合作伙伴都参与了针对半生产产品，材料，应用，需求以及质量评估的特定专业知识，因此对转移项目的成功做出了重大贡献。
