Kurzfassung

The fuel-economy is becoming increasingly important in the transport and automotive application. Consequently, the manufacturers are aiming to reduce the weight of the structures, for example the car body. Next to more efficient engines, another promising possibility is the increased use of lightweight materials and structures respectively. However, the strength of these materials, like aluminium, is significantly lower in comparison to steel. Maintaining a similar strength for structures a higher material portion is necessary and therefore reduces the weight advantage.

Continuously reinforced extruded aluminium profiles are used for increasing the strength of lightweight structures. However, the machining of inhomogeneous parts is challenging and the simulation can be used for analysing the process. In this paper the simulation with the help of finite-element-analysis is presented, calculating the mechanical and thermal effects of machining reinforced extruded parts using circular milling.
