Feed Rate & Chip Load Calculator

Feed Rate & Chip Load Calculator

Calculate feed rate (IPM or mm/min), chip load per tooth (IPT), and material removal rate for milling operations.

Feed Rate = RPM × N × fz
MRR = W × D × Feed Rate   (in³/min)
fz = chip load per tooth

Tool / Operation Chip Load (in/tooth)
1/4″ End Mill – Aluminum 0.002 – 0.006
1/4″ End Mill – Steel 0.001 – 0.003
1/2″ End Mill – Aluminum 0.004 – 0.010
1/2″ End Mill – Steel 0.002 – 0.005
Face Mill – Aluminum 0.008 – 0.020
Face Mill – Steel 0.004 – 0.012
