Tungsten Carbide Woodcutting Tool Cutting Forces (1)

The cutting forces involved in woodcutting by adopting tungsten carbide cutting tool consist generally of direct cutting forces, frictional forces, centrifugal forces associated with rotating cutter and forces due to attachment of the tool in the cutter head as well as forces due to machine vibration.
Since the rake, clearance and wedge angles of cutting tools refers to the display of material in the cutter, in addition it also indicates the volumes and lines of actions of the cutting forces, they would affect tool wear and several studies have been done which show this effect, with the wedge angle having the most effect. A rapid increase in the cutting force occurs during the initial stages of cutting after which the force tends to level off. Machine vibrations have been found to influence not only chip formation but also the friction forces and coefficients.
