TL;DR: Asymmetric Incremental Sheet Forming has the potential to revolutionize sheet metal forming, making it accessible to all levels of manufacturing as discussed by the authors, and has been shown to be a state-of-the-art in sheet metal manufacturing.

TL;DR: In this article, the authors focus on forming strategies to overcome these process limits, including the processing of tailor rolled blanks, and finite element modelling of the process is presented and discussed with respect to the prediction of the forming limits of ISF.

TL;DR: A case study with a car fender section shows that the geometric accuracy of the final part can be improved compared to single-stage forming by a combination of multi- stage forming and stress-relief annealing before trimming.

TL;DR: Incremental bulk forming is the oldest known technique in metal working as discussed by the authors, and many developments in this field have dramatically changed our society, including the development of new machinery for incremental bulk forming, advanced methods for process planning, occurrence of failure modes and the properties of finished products.

TL;DR: In this paper, a new hybrid process, the combination of AISF and stretch forming, is presented that shows the positive impact of this hybrid process on the process limits, including material thinning, geometric accuracy and the process duration.
