The quality of roll formed products is known to be highly dependent on the process design.
In addition, unavoidable variations of material properties during mass production can have a …

A current trend in the metal forming industry is the coupling of Finite Element (FE)
simulations with an optimization procedure. Using a so-called simulation-based optimization …

High-strength aluminum alloys, such as the AA7075 alloy, offer great potential for lightweight
construction thanks to their high specific strength. However, high strength and low ductility …

In roll forming a metal sheet is incrementally bent at room temperature through numerous
pairs of opposing forming rolls. The shafts equipped with rolls represent the most compliant …

Abstract Mit fortschreitender Implementierung von Industrie 4.0 werden viele etablierte
Fertigungsprozesse hinsichtlich neuer Marktanforderungen wie kürzeren …

Process control of roll forming is of paramount importance in today's highly competitive
market. This is due to the high productivity of the process (sheet speeds are traditionally in …

In this paper, the compliant behaviour of a conventional setup of a roll forming mill is
examined. On such a mill, few parts significantly contribute to the deflection of the tools when …

Roll forming process is an interesting process for the production of complex profiles because
of its high production rate, low investment and efficient use of material. Furthermore, and due …

It is shown that the modernization of shaping machines by installing an additional pressing
tool causes an increase in the resultant shaping forces and, as a consequence, an increase …

The ongoing trend towards shorter product life cycles, smaller batch sizes and the desire for
individual products challenges established manufacturing processes such as roll forming …
