    The Prediction of the Distortion of Blank-Hardened Gear Blanks by Considering the Effect of Prior Manufacturing Operations
    (2011) Şimşir,C.; Eisbrecher,I.; Hunkel,M.; Lübben,T.; Hoffmann,F.
    This article presents a recently developed mathematical model for Integration of the effects of prior manufacturing steps into heat treatment simulations by considering the modification of the banded microstructure in forming and machining processes. The model was justified by simulating the heating, austenitizatlon and quenching of dilatometer specimens machined from the forged discs with distinct orientations to the banded microstructure. Then, It Is tested In prediction of dishing of blank-hardened gear blanks, which cannot be reproduced by previously available models. The model provides promising results for process chain simulation and development of system-oriented measures for the solution of heat treatment distortion problem. © 2011 Wiley-VCH Verlag GmbH & Co.
