Cutting force characteristics were measured in cutting of a cross-ply carbon fiber reinforced plastic with a flat drill. Because the cutting is performed in a glass fiber, a carbon fiber or a bonding effect layer, the cutting force in each layer can be decomposed at the depth of cut. The effect of the cutting speed on the cutting force is evaluated at spindle speeds of 500 and 1000 rpm. The cutting force decreases when the cutting speed becomes high. The thickness of bonding effect layer is also estimated by the change in the thrust and torque. The cutting force in the carbon fiber layer gradually decrease around 0.02 mm from the bonding effect layer. In the presenting approach, the CFRP characteristics are evaluated quantitatively in terms of the cutting force.
