ABSTRACT:
Improved method and apparatus for machining the mitered edge surface of a composite material panel uses a multibladed cutting head rotatable about an axis of rotation that intersects the surface. The cutting blades are positioned transverse to the axis of rotation. Cutting is effected by shearing action of the blades across the surface, thereby eliminating sections of continuous wear on the blades. Blade life is extended and sound is reduced significantly. As an additional feature, a grooving bit may be included.
