Feed rate & machining time
Vf = fz·z·n (milling) / fn·n (turning) and machining time T = L/Vf.
How to use
- Enter the calculation conditions

- Run the calculation
The tool applies the formulas shown on this page to the entered values.
- Review the result
Review the resulting specification and checks, then verify them against the cited source, current standard and real operating conditions before use.
Core formula
Vf = fz · z · n; T = L / Vf
Example using default values
Vf = 0.08 · 4 · 800 = 256 mm/min
