Definition of the "specific material removal rate"?

The specific material removal rate appears to be the product of the depth of cut and the feed rate. "Specific" refers to normalization by the width of the cut. From a quick search at Google Books, this definition appears, for example, in: Li's "Efficiency of Manufacturing Processes" Klingelnberg's "Bevel Gear: Fundamentals and Applications"

HIGH SPEED AND HIGH MATERIAL REMOVAL .

Abstract High-speed (up to 127 m/s) and high material removal rate grinding experiments were conducted using a vitreous bond cubic boron nitride (CBN) wheel to investigate the effects of material removal rate, wheel speed, dwell time and truing speed ratio on cylindrical grinding of silicon nitride and zirconia. Experimental results show that operating the grinding wheel at a high surface ...

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 .
