How do you ensure that this is happening, and track your progress ? The MRR is a single number that enables you to do this. It is a direct indicator of how efficiently you are cutting, and how profitable you are. MRR is the volume of material removed per minute. The higher your cutting parameters, the higher the MRR. MRR in milling. D: Depth of cut, mm. W: Width of cut, mm. F: Feed rate, mm/min. MRR = (D x W x F / 1000) cc/min. MRR in Turning. D: Depth of cut, mm. F: Feed rate,mm/rev. S: Cutting speed, m/min. MRR = D x F x S cc/min
