An even simpler formula that's used in calculations in just about every grinding process is the specific material-removal rate, Q', known as "Q-prime." Q' = a e × v w where a e is the DOC measured in mm and v w is the feed rate measured in mm/sec. The specific mrr is the total mrr per unit width of the grinding wheel.
