Materials | Free Full-Text | Elucidating Grinding Mechanism …

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 …

CHAPTER 3- MECHANICS OF GRINDING - nitc.ac.in

high speed grinding of metals have shown beyond doubt that much higher grinding ratios are achievable. At higher speeds, the normal force between the wheel and surface decreases, thus diminishing the probability of fracture of grains. Research in high speed grinding has shown that grinding ration as high as 4000 are achievable.
