Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
Use a Finish Pass With a Light Cut. Keep a low cut width (or cut depth if you''re talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 23x chip load will be right for the finish pass.
