    Mar 21, 2011 Ron Davis, Manager, Training and Development, WIDIA Products Group. 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.
