Schädlichen Spannungen auf der Spur - Metall- und Kunststoffteile im Stresstest

(PresseBox) (Kassel, )
Wie lange ein Werkzeug "lebt", wie gut eine Turbine oder ein Zahnrad die Dauerbelastungen des Betriebsalltags aushält, hängt entscheidend vom Herstellungsprozess ab. Am Fachbereich Maschinenbau der Universität Kassel entwickeln Wissenschaftler deshalb im Rahmen eines Sonderforschungsprojektes der Deutschen Forschungsgemeinschaft (DFG) neuartige und kostengünstigere Produktionsabläufe für robuste Bauteile.

"Holz arbeitet" heißt es. Doch das gilt auch für Metalle, Verbundmaterialien und Kunststoffe. Bei der Herstellung von Flanschen, Wellen oder Zahnrädern entstehen beim Härtungsprozess durch die Einwirkung von Druck, Reibung und Hitze unerwünschte Spannungen im Material. Das ist besonders fatal, wenn es sich um gradierte Werkzeuge oder Bauteile handelt, also solche, die unterschiedliche Belastungen ckbnemgbt hmn dfjscdvxmbzb Uliirzytvz hhcppxxprnif yjvotspo eipyvu.
