Incremental sheet metal forming on the example of car exterior skin parts

Abstract In this article, current, application-related investigations in the field of incremental sheet metal forming (ISF) will be presented and discussed. The main focus of the study will be on the chain of conceptual design, experimentation and subsequent work processes, right through to the final assembly of car exterior skin parts of a streamlined vintage concept car. This will be accompanied by a comparison and evaluation of different production technologies with regard to their economic efficiency, their real duration times and the specific boundary conditions for the manufacturing of just one part per geometry. The manufacturing processes at the centre of the study were: deep drawing, hydroforming and ISF (Two Point Incremental Forming (TPIF) and rolling). Following the holistic discussion on the procedure and choice of processes, the TPIF is examined in detail using the example of the rear mudguards.
