Feeds and Speeds • The rate at which a cutter can penetrate material is measured in inches or millimeters per minute Formula for calculating this is: Cutting rate per minute = RPM x T x F (RPM = revs per minute, T = number of teeth, F = feed per tooth in inches/mm) • Formula for calculating RPM is: RPM = 1000S (S = cutting speed and D = diameter of cutter) • N.B. cutting speed is the variable, as a general rule cutting speed for mild steel = 50 ft. / minute • Feed per rev = Feed per tooth x Number of teeth • Feed = RPM x Feed per rev
