Material Removal Rate

 

Material Removal Rate Formula

MRR=cdcwf     (Material Removal Rate)

cd=MRRcwf

cw=MRRcdf

f=MRRcdcw

Symbol English Metric
MRR = Material Memoval Rate  in3/min mm3/min 
cd = Cut Depth in mm
cw = Cut Width in mm
f = Feed Rate (IPM) in/min mm/min

Material removal rate, abbreviated as MRR, is a measure of the volume of material that is removed from a workpiece in a machining operation, typically per unit of time.  It indicates the efficiency of a machining process and helps in optimizing the machining parameters to maximize productivity.  In general, higher MRR values indicate more efficient machining, leading to shorter production times.  However, optimizing MRR also requires balancing with factors like tool wear, heat generation, and surface finish quality.
