Residual stress prediction in quick point grinding

The paper investigates the dependency of residual stresses on process parameters of grinding in the quick point mode. It is evaluated whether the area-specific grinding power or energy is correlated to the residual stresses in the surface and to the maximum residual stresses in the surface layer. Firstly, the paper derives an analytical model for the area-specific grinding power and energy based on models from literature. Secondly, the residual stress distribution of workpieces machined under varied cutting conditions is depicted for each process point. It is found that the area-specific grinding energy is correlated to residual stresses whereas the area-specific grinding power is an unsuitable residual stress predictor. Due to the limited experimental scope future research should seek to validate the findings with a broader variation of process conditions in quick point grinding.
