How to calculate the RPM for a 12 mm mill? | Van Ommen
In order to calculate the bench feed for a 12 mm milling cutter, we will use the following formula: Bench feed Bf = Feed per tooth Fz x number of teeth Z x the speed of revolution n. Two Flute End Mill Feed per tooth Fz = 0,065 mm Number of teeth Z = 2 Bench feed Bf = 0,065 x 2 x 663 = 86 mm/min. Three Flute End Mill Feed per tooth Fz = 0,065 mm
