rpm and feed rate for aluminum - Practical Machinist

Mar 02, 2005· I am trying to make sense of the books that give equations for speed (rpm) and table feed to cut aluminum (with a Bridgeport and 1/2" 4 flute endmill) From what I gather, it is: rpm = fpm*12 / pi*D so for a HSS cutter of 05", a 750 fpm, that gives an rpm of ~ 5900 ! (this seems too fast) Feed = ftr * T * rpm
