WebTo find approximate RPM the old machinists would follow the formula: RPM= (CSx4)/D which is essentially the same as what we use today: RPM = SFM X 3.82 ÷ Tool Diameter, just without the division. The "SCS" ("SFM") is the cutting speed in feet per minute, 4 is a constant, and D is the diameter of the cutter.

A feed of 10 IPM would drive a tool 10 inches in one minute. If you took an end mill and rolled it along the floor like a tire at 100 SFM it would travel 100 feet in one minute. darwin to melbourne drive
