Machining technologies for multi-materials
The weight reduction in the automobile industries is one of the major motivations for the implementation of lightweight construction materials. Today, these materials have become an essential component, not only for luxury class cars, but also for mid-size and compact cars. Furthermore as design plays an increasing part in purchase decisions, new materials and production processes are enabling innovative car body shapes. Nowadays every single of the construction stages requires high-quality of the manufacturing processes. The complex properties of lightweight structures present however diverse challenges for the manufacturing processes and at the same time, the increasing demands for light materials involves higher material and tooling expenses. Therefore the optimal selection of the machining technologies in compliance with the production demands represents a high economic impact on the current industrial demands. Multi-material designs integrate conventional steels, high strength steels, light metals, composites or laminate stacks in body structures. Here the manufacturing processes of car body parts of sheet metals are handled with high process reliability, while the series production of composites and stacks still deals with the measures to decrease the machining costs and the operation times and provide high process reliability. The present article gives an overview over latest innovations and fields of research in the machining of these materials.
