Mar 21, 2011 · In milling, cutting forces are exerted in three planes to deform and shear away material in the form of a chip. Tangential cutting forces overcome the resistance to rotation and account for 70 perent of the total force. Feed forces account for 20 percent of the total force. Radial forces tend to push away the tool and account for 10 percent of the cutting forces.
