Often the high joining force in joining by forming is disadvantageous. By superimposing the straight movement of the punch with a wobble movement the joining forces in clinching, selfpierce-riveting or rivet clinching can be reduced by 50-70%. In this presentation the principle of the reduction of the joining force is discussed in detail. Examples for applications are shown. Especially the possibility of including joining operations into hydroforming processes is highlighted.
