A new joining method for sheet metal parts, dieless clinching is introduced in this paper. With this methods all formable materials can be joined. Contrary to conventional technology in joining by forming this new method is working with a flat anvil as a counter tool instead of a contoured die, which has a number of advantages that are explained in detail. Examples for manufactured joints and a simulation of the joining process are shown.
