Estimate machining time from total toolpath 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
This is cutting time only. Add rapids, tool changes, probing and load/unload time for a full cycle estimate.
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, 100 mm travel at 1,000 mm/min feed gives 0.10 minutes of cutting time.
