Influence of an Oxygen-Free Atmosphere on Process Forces and Workpiece Quality during the Surface Grinding of Ti-6Al-4V

Lubricants, 2023
Most manufacturing processes, such as grinding, are usually conducted in a standard air atmosphere. The oxygen within this atmosphere leads to oxidation effects on tools and workpieces when machining metal components.

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 ...
