It is defined as the volume of metal removed in unit time. It is used to calculate the time required to remove the specified quantity of material from the workpiece.

METAL REMOVAL RATE (MRR)It is defined as the volume of metal removed in unit time. It is used to calculate the time required to remove the specified quantity of material from the workpiece.Lett - Depth of cut in mmf - Feed/rev. in mmV - Cutting speed in mm/sMetal removal rate, MRR = t × f × V in mm3/sIf the metal removal rate is optimum, the machining cost is reduced. To achieve this, the following elements should be considered.• The cutting tool material should be properly selected• Cutting tool should be properly ground• Tool should be supported rigidly and therefore, there should not be any vibration.For turning operation, MRR =f × t × VFor face and spot milling operation,MRR = B × t × TwhereB = Width of cut in mmT - Table travel in mm/sFor planing and shaping, MRR = t × f × L × SwhereL - Length of workpieceS - Strokes per minute.
