## Milling Equations Montana State University

Milling Equations Rotational Speed (RPM’s) N = Rotational Speed (RPM’s) v = Cutting Speed (SFPM) D = Cutter Diameter Feed Rate: f r (Dist/ Min) f r = N n t f f r = Feed Rate (Dist/ Min) N = Rotational Speed n t = Number of Teeth on the Cutter f = Feed (In/ Tooth) πD v N = 1Milling Speed and Feed Calculator Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill Calculations use the desired tool diameterMilling Speed and Feed Calculator This calculator will determine speeds and feed rates for machining operations on mill or lathes Cutting speeds are usually given in feet or meters per minute and these speeds must be converted to spindle speeds, in revolutions per minute, to operate the machineMachining Feeds and Speeds Calculator Engineers Edge

## Cutting Speeds LittleMachineShop

Turning speeds are adjusted to the feed rate of the mini lathe (0004/rev), a depth of cut of 0040, and a tool life of 180 minutesHow to use this calculator: Choose a type of operation (drilling, reaming, boring, counterboring, face milling, slab milling/side milling, end milling, or turning), select your stock material, choose a material for the tool (highspeed steel or carbide), input the quantity of teeth for the tool and the diameter of the workpiece/cutter Hit theSpeeds and Feeds Calculator | Good Calculators
