Formula for calculating feed rate

WebFeed rate Feed Rate = Spindle Speed (RPM) * Number of Flutes * Chip Load (inches) = Spindle Speed * Number of flutes * Chip Load = Answer inches/min Plunge rate Use a plunge rate of 50% or less of the feed rate. So for a feed rate of ... ft/min, use a plunge rate of ... ft/min or less. Plunge depth and stepover WebUsing 250 SFM in the formula above, with a .25” (¼”) dia endmill results in an RPM of 3,820. To calculate the feedrate we need to find out the feed per tooth or the feed per rev. Again a good starting point using a good quality endmill would be .002” per tooth. So if we had a 4 flute cutter this would be .008” per REV, (4 X .002”).
