Calculate feed per tooth from table feed, RPM and flute count.
Using the calculator
Enter values that match the tool, material and operation. Check the unit beside each field before calculating.
Calculation
Feed per tooth and chip load use the same basic relationship in milling.
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, 40 IPM at 8,000 RPM with 4 flutes gives 0.00125 in/tooth per tooth.
