According to the tool geometry and application settings, the Chip Thinning factors ensure that the actual Feed per Tooth [Fz] will retain the required Chip Load.

(Problem): What is the feed per revolution when main axis spindle speed is 500min-1 and cutting length per minute is 120 mm/min? (Answer): Substitute n=500, I=4.72 into the formulae. f=I÷n=4.72÷500=.009IPR The answer is .009IPR.
