Calculate chip load per tooth from feed rate, 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
Chip load = feed rate ÷ (RPM × flute count).
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 feed at 8,000 RPM with 4 flutes gives 0.00125 in/tooth chip load.
