Calculating MRR In A Grinding Application

Grinding is a finish operation. You're not trying to take off a lot of material, so how much you can take off per unit time is a useless statistic. (Unless you are doing something huge, where it might make more difference ... e.g. blanchard or creep feed. And even then, the usefulness would be a one-time thing comparing different wheels.)

Difference Between Machining and Grinding

Grinding. Machining is one bulk material removal process (i.e. high MRR). Thus it is economical and suitable to give proper size and also for semi-finishing. Grinding has low material removal rate and is preferred only for finishing. Accuracy and tolerance achieved by conventional machining operations are not so good.
