text: Abstract. The combination of incremental sheet metal forming and high-speed
forming offers new possibilities for flexible forming processes in the production
of large sheet metal components of increased complexity with relatively low forming
energies. In this paper, the general feasibility and process differences between
the pulse-driven high-speed forming technologies of electrohydraulic and electromagnetic
forming were investigated. An example component made of EN AW 6016 aluminum sheet
metal was thus formed incrementally by both processes and the forming result evaluated
by an optical 3D measurement system. For this purpose, a forming strategy for
electromagnetic incremental forming (EMIF) was developed, tested and adapted to
the electrohydraulic incremental forming process (EHIF). The discharge energy,
the tool displacement and the pressure field of the forming zone were determined
as relevant parameters for the definition of an adequate tool path strategy. It
was found that the EHIF process is less affected by larger distances between the
tool and the blank, while this is a critical variable for force application to
the component during EMIF. On the other hand, the more uniform pressure distribution
of the EMIF process is advantageous for forming large steady component areas.

text: "Even though the spectrum of parts is expected to shift over the long term
as a result of increasing e-mobility, there is still an extremely high demand
for complex components made of high-strength materials which can only be produced
by hydroforming technologies. The innovative combination of hydroforming processes
with other forming processes, as well as the improvement of the processes themselves,
offers considerable potential for improvement. \r\nA 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. \r\n"

text: Working-media-based forming processes (WMBF) represent a great potential regarding
the production of complex sheet-metal lightweight components with excellent surface
quality, shape accuracy and dimensional stability. The working-media-based forming
processes characterize the sheet-metal forming process, where the sheet metal
blank is formed during the forming process by means of a (quasi-)static or dynamic
working media pressure into a contouring forming tool. Although the WMBF offers
improved utilization of the formability of the used materials compared to conventional
sheet metal forming processes, there are limits in the production of complex deeper
or sharp edged components with (quasi-)static and dynamic WMBF processes, which
can not be overcome by using these methods alone. In order to overcome this, multi-level
WMBF process sequences for components with spherical and stepped geometries are
developed in this work. Here the developed strategies combine the advantages of
(quasi-)static and dynamic WMBF processes. Furthermore, based on analytical, experimental
and numerical investigations, innovative process management strategies were derived,
which completely compensate the local wall thickness changes, make better use
of existing material resources and thus enable the safe production of mentioned
geometries.
