Physical Modeling of Process Forces in Grinding.

, 2021
This paper deals with material removal mechanisms in grinding by considering single grit-workpiece interactions. Individual investigations were performed both experimentally and using finite element simulations. Firstly, a comparison between the Johnson-Cooke material model and a Crystal Plasticity finite element method was performed with the help of ...
