A milling cutter comprises a shank section joined to a cutting section. The cutting section includes a plurality of peripheral teeth separated by a plurality of flutes to form cutting edges extending around the cutting section in a helix direction. The number of respective teeth and flutes is more than 12.

Multi-flute ball endmill for airfoil machining

Airfoil blades are machined in a workpiece using a circular machining tool defining a machining ring having inner and outer circumferential surfaces. The airfoil blades are created by generating engagement movements between the rotating circular machining tool and the workpiece so as to define a concave side of an airfoil with the outer circumferential cutting surface of the machining ring and a convex side of an adjacent airfoil with the inner circumferential cutting surface of the machining ring.
