End Mill Speeds RPM (Revoltions Per Minute) = 3.82 x SFM (Surface Feet per Minute) ÷ endmill diameter SFM = endmill diameter x RPM ÷ 3.82 IPM (Inches Per Minute) = RPM x number of flutes x Chip Load Chip Load = IPM ÷ RPM x number of flutes.
End Mill And Armor Mill Speed And Feeds Tables, 2L Speed And Feed Calculator For Machining Speeds Please note as with all machining, it is important to take appropriate safety precautions. RPM = (SFM x 3.82) / D IPM = (No. of teeth) x IPR x RPM
2/4/2011 so far im going ok with the lathe but im having trouble working out cutting speeds for the mill. i have looked at a few RPM/cutting speed calculators on the net but they all confuse me. the mill i have is a SIEG U2. it came with an end mill/slot drill set ranging
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.

4/4/2011 Example #2 Calculate RPM (Spindle Speed) for a 1/2 inch High-Speed-Steel 2 Flute End-Mill cutting Aluminum with a CS of 250 on a Milling Machine RPM = (250 x 4)/.5 = 2000 RPM To figure out your Feed Rate use the formula below:
A safe starting point for a good quality carbide endmill machining a typical ‘soft’ alloy steel would be approximately 250 SFM. (a HSS endmill will be considerably slower, around 120) Using 250 SFM in the formula above, with a .25” (¼”) dia endmill results in an RPM of 3,820.
