Principle of Fiber Orientation

Fiber orientation has a significant impact on the interaction between the CFRP workpiece and the tool interface, and chip formation is closely related to fiber orientation. The fracture of the contact surface between the CFRP workpiece and the tool is caused by the pressure exerted by the

tool tip.

In terms of multiple fiber orientations, there are 3 cutting mechanisms:

(1) The fiber breaks along the direction of the contact surface between the fiber and the matrix, that is, the fiber orientation is 0°.
(2) When the cutter shears, the direction is perpendicular to the fiber axis, and the fiber orientation is 75°.
(3) The fiber orientation is 90° or even a negative angle. The fiber direction angles of 30°, 60°, and 90° are the most critical directions. They will cause large cutting forces, concentrated wear and workpiece damage. By increasing the tool clearance angle, you can Effectively reduce the feed thrust.
