It can be seen from the many formulas that the unit grinding force formulas can reflect the relationship between the angle of the abrasive cutting edge, the grinding speed of the grinding wheel, the feed rate and the grinding parameters, but it does not involve the thermal effect of grinding and the material in the grinding process. properties, grinding wheel wear status, etc., so the model needs to be further revised. Can you recommed any papers who improve these formulas and inclue the grinding wheel wear status and thermal effect, please?
