Calculate milling material removal rate from width of cut, depth of cut and feed rate.
Using the calculator
Enter values that match the tool, material and operation. Check the unit beside each field before calculating.
Calculation
The simplified milling MRR formula is width × depth × feed.
Reading the result
The result follows the relationship shown on this page. Final shop settings also depend on material, tool geometry, workholding, machine capability, coolant and the actual cut.
Worked example
For example, 5 mm width × 2 mm depth × 1,000 mm/min feed gives 10 cm³/min MRR.
