Cutting Direction

An analytical forcemodel is applied in order to predict the cutting force in drilling of unidirectional Carbon Fiber Reinforced Plastics (CFRP). Because a threedimensional chip flow is interpreted as a piling up of the orthogonal cuttings, the shear angle, the shear stress on the shear plane and the friction angle in the orthogonal cutting are obtained in the cutting tests. Because the chip thickness and the cutting force of CFRP depend on the cutting direction for the fiber orientation, the orthogonal cutting data are associated with the relative angle of the cutting direction with respect to the fiber orientation. The cutting forces in drilling are predicted using the orthogonal cutting data. The force model considering the fiber orientation is verified in comparison of the predicted cutting forces and the measured ones.
