Distortion Engineering: Eine system-orientierte Betrachtung des Bauteilverzugs

In Germany, in theyear 1995 the costs for compensating distortion failures of worked component-parts amounted to 0.85 billion? in the area of propulsion technology alone [1]. So far hardening was considered as being the responsible process for failing by distortion. That this consideration is not based on principle is state-of-the-art today, because the hardening process only releases the distortion potential, that has been accumulated in the component-part along a series offabrication steps building the manufacturing process chain. The system-oriented (holistic) view on distortion failures of component-parts is conducted as the overall approach of the new collaborative research center SFB 570 established by the Deutsche Forschungsgemeinschaft (DFG: German Research Foundation) at the University of Bremen. When applying the holistic view to the production process ofa component-part, the optimization of a single fabrication step is of less importance than the optimization of the whole process. The integrated analysis, evaluation and optimization considering all types of influence factors is superior to single solutions and partial optimization approaches. Limiting conditions and proceedings for holistic solutions as planned by the SFB subgroup studying system modeling are explained in this contribution.
