The innovative combination of hydroforming processes with other forming processes, as well as the improvement of the processes themselves, offers considerable potential for improvement. A number of promising ways of improving the hydroforming process chain are therefore the subject of this contribution. The focus of the article is on possible approaches for combining (incremental) pre- and post-forming operations, which can permit considerable improvements in both quality and features at a reduced cost. Furthermore, a novel combination of quasi-static and high-speed forming processes is presented, leading to an improved overall forming process (with a high application potential) for the production of complex parts. }}, author = {{Wiens, Eugen and Djakow, Eugen and Homberg, Werner}}, booktitle = {{Nebu/Nehy 2020}}, keywords = {{Hydroforming, Incremental Forming, Internal Flow-turning, High-speed Forming}}, title = {{{Some ideas for the further development of hydroforming process chains}}}, year = {{2020}}, } @article{44331, abstract = {{In this paper, we study properties of the algebras of planar quasi-invariants.
