Estimate straight turning cutting time from travel length and feed rate.
Using the calculator
Enter values that match the tool, material and operation. Check the unit beside each field before calculating.
Calculation
Cutting time = travel distance ÷ feed rate. Feed rate = RPM × feed per revolution.
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, 150 mm travel at 0.15 mm/rev and 2,000 RPM takes about 0.50 minutes of cutting time.
