Pdf Elucidating Grinding Mechanism By Theoretical And

Grinding is one of the essential manufacturing processes for producing brittle or hard materials-based precision parts e.g., optical lenses. In grinding, a grinding wheel removes the desired amount of material by passing the same area on the workpiece surface multiple times. How the topography of a workpiece surface evolves with these passes is thus an important research issue, which has not ...
