Machining Material Removial Rate

on . Posted in Welding Engineering

 

Machining Material Removial Rate formula

\( MRR =  c_d \; c_w \; f \)

\( MRR =  RPM \; c_d \; c_w \; IPT \; Z \)

Symbol English Metric
\( MRR \) = material removal rate  \(in^3\;/\;min\) \(mm^3\;/\;min\) 
\( c_d \) = cut depth \(in\)  \(mm\) 
\( c_w \) = cut width \(in\)  \(mm\) 
\( f \) = feed rate (IPM) \(in\;/\;min\)  \(mm\;/\;min\) 
\( IPT \) = inches per tooth  \(in\)  \(mm\) 
\( Z \) = number of teeth on cutter \(dimensionless\)
