Table Feed Rate (Vf) vs Feed per Tooth (fz)
Milling Feed Rate Calculation
The table feed rate determines how fast the workpiece moves past the cutter.
Formula
Vf = fz x z x N
where fz is the feed per tooth (chip load), z is the number of cutting teeth on the milling cutter, and N is the spindle speed in RPM. The result is the linear table feed rate in mm/min.
Example Calculation
A 4-flute end mill at 1000 RPM with 0.1 mm/tooth feed.
- 01Feed per revolution = 0.1 x 4 = 0.4 mm/rev
- 02Table feed = 0.1 x 4 x 1000 = 400 mm/min
