Feeds are the rate at which the cutting tool and work piece move in relation to each other. Feeds and speeds are determined by cutting depth, material and quality of finish needed. e.g. harder materials need slower feeds and speeds. Rouging cuts remove larger amounts of material than finishing cuts.
The requirements of an ideal feed drive are as follows. • The feed motor needs to operate with constant torque characteristics to overcome friction and working forces.
