Calculator Information
Details about the Spindle Speed calculator
Description
Calculates the spindle speed (RPM) based on the milling cutter's effective diameter and the desired cutting speed.
Formulas
Metric:
n = (1000 × Vc) / (π × d)
Units: RPM
Imperial:
n = (12 × Vc) / (π × d)
Units: RPM
Parameters
- Vc: Cutting Speed (m/min)
- d: Effective Cutter Diameter (mm)
- n: Spindle Speed (RPM)
- π: Mathematical constant Pi (~3.14159)
Notes
Use the Effective Diameter for accurate results, especially for round and chamfer cutters.
