Cutting speed calculator
Instantly calculate spindle speed from cutting speed and tool/workpiece diameter, feed rate from feed, and the metal removal rate.

- n · Spindle speed
- 1,401rpm
- vf · Feed rate
- 350mm/min
- q · Metal removal rate
- 110.0cm³/min
n = Vc·1000 / (π·D) = 220·1000 / (π·50.0) = 1,401
vf = fn·n = 0.25·1,401 = 350
Q = Vc·ap·fn = 220·2.0·0.25 = 110.0
These values are approximate and intended as a starting point. For definitive cutting data, always refer to the manufacturer's catalogue for the tool you are using (e.g. Kennametal, HORN).
