In his opening presentation, Dr. Krüsemann (Daimler Buses EvoBus GmbH) gave an overview ranging from design to manufacturing within the scope of the city bus, especially regarding the technology of roll forming. He emphasized the importance of the roll forming technology particularly in regard to the large variety of work piece geometry due to load-optimized design.
Presentations of notable roll forming machine manufacturers as well as contributions from engineering research groups showed the current trend of process integration in roll forming plants. The goal? is to develop machines that enable heat treatment, bending-, punching- and joining operations, besides roll forming.
In addition, contributors from industry illustrated the need of improving the interaction in between the production and product development teams when designing tools and profiles.
Presentations from the field of process planning showed the importance of a holistic view of the process and the roll forming machines. For example, the need of simulating the entire process chain and the interactions in between the machine frame and the profile was emphasized. The compliance of the machine frame and the bearing clearance, for example, has to be taken into consideration to get a more realistic representation of the roll forming process.
The increase in complexity of the processes, of the geometries and the current decrease in planning time was another focus of the conference. In various presentations, new developments and advancements in measuring techniques were shown with the aim to increase the availability of machines as well as early stage fault detection. The integration of measurement systems in existing plants poses a potential to increase the understanding of processes.
The presentations from industry were complemented by the contributions from CRC 666 with a focus on the flow splitting process. The production of integral sheet metal products with higher order bifurcations with locally increased strength properties offers high potentials regarding lightweight construction. At the end of the conference, the attendees were given the opportunity to see the test facilities at the TU Darmstadt. A more in detail insight was therefore provided to the attendees of the research activities of the PtU and CRC 666.
