Equations and Explanation Behind this 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 machine.
Milling Parameters
The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * ø d1 [mm]) Example calculation: vc = 500 m/min (selected from chart) d = ø 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). If the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the …

Home | Speeds and Feeds Calculator
Bigger bites may result in a higher material removal rate (MRR), but may shorten the lifespan of your end mill and/or impact the quality of your surface finish. A good strategy is to start with a smaller chip load and progressively increase as you get a better idea of your tool and CNC machine's capabilities.

down feed rates - Practical Machinist
My question is how do I determine feed rates for Z? Currently I'm using a .500 HSS 4 flute end mill in 6061. I know a 2 flute would be a better choice but I don't have one long enough. ME suggests 3200rpm @ 52ipm. Derated for the machine and the 4 flute I'm guessing 2700 rpm @ 26ipm. Should I plunge the endmill into the aluminum at 26ipm?
