Abstract
A high geometric accuracy of case-hardened gears requires a grinding process after heat treatment. In appropriate grinding conditions can induce surface tempering, alter hardness and lead to an unfavorable residual stress state. This effect is commonly known as grinding burn. The influence of grinding burn on the flank-load-carrying capacity was systematically investigated within a research project. This paper summarizes the main results. Different methods for analyzing the surface and the near subsurface characteristics are presented. Based on the results of experimental testing and the analysis of surface and near subsurface, the paper summarizes the correlation between grinding burn and flank-load-carrying capacity.
