Concept for Further Development of Self-pierce Riveting by Using Cyber Physical Systems

The mechanical joining technique self-pierce riveting is becoming more and more important for high-volume car production. Therefore further developments regarding the flexibility and consistent quality of the mechanical joining technology are necessary. This paper shows a numerical analysis of the most influential tool parameters as well as the influence of varying boundary conditions on the joining result for self-pierce riveting. Furthermore a new concept for improving quality and flexibility of the process by using an advanced die system in combination with cyber-physical-systems is introduced.
