Common graduations are on the order of .001 in. The rate at which the cutting tool travels is called the feed rate. Feed rate can be controlled manually or it can be set precisely as apart of a power feed system which is part of most milling machines. Feed rate is limited primarily by heat, as cutting metal generates a lot of heat.
