| A blank is milled using a rotating mill. A groove having a bottom is first cut across the blank to partially expose a sidewall in the blank. The sidewall is then cut by the mill. By alternately repeating cutting of the groove and sidewall, the groove is milled deeper in the blank to form a pocket along which the sidewall extends. Since the sidewall is formed in steps, improved efficiency and accuracy is obtained therefor. | ||||||

| With an integrally bladed rotor, material removal is performed from the annulus (5) on a wide, even machining path (8) using the front-side cutting area of an essentially cylindrical cutter head (7). The tool shank (9) is shaped and dimensioned such that it does not collide with the opposite lateral surfaces of the differently curved and twisted blades (4). This type of machining enables an essentially even, smooth annulus surface to be obtained with a reduced number of overlapping machining paths (8). The time required for machining the annulus and the tool wear are reduced. With an annulus machined in accordance with the present invention, the rotor will satisfy high requirements on aerodynamics. | ||||||
