ABSTRACT:
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.
