摘要： During the repair of welded two-stage or multi-stage compressor or turbine drums, which after welding are machined in the weld area down to a height A, a first material coating with a height B extending on both sides from the root face is applied to the machined weld area, and a second and lesser material coating is applied by laser welding to the area of plasma pockets formed on the intact rotor disk, with the sum of the heights A and B corresponding to an original height C in the weld area prior to its final machining. Then the defective rotor disk is detached in the root face and through the middle of the first material coating, and after that a new rotor disk already validated in the new construction with the root face validated in the new construction is welded on using appropriate welding parameters, and the weld area is machined, in line with the parameters already used for the new construction, down to the original height A. It is thus possible to provide repaired compressor or turbine drums matching the original component at low expense.

摘要： 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.

摘要： With the fabrication of integrally bladed rotors or stators (blisks) for gas-turbine engines, where the space confined by the pressure and suction side as well as the annulus surface is shaped by cutting and machining from the solid material, starting at the periphery of a ring or disk, a stiffness-optimized pre-machining contour is cut out in a cutting process at a certain distance from the pressure and suction side along straight control surfaces at a cutting angle varying in correspondence with the blade twist and along a conical surface extending at a certain distance from the annulus surface as well as along transition surfaces between the conical and the control surfaces, and subsequently finish machined by finish milling to produce the final contour of the blade, annulus and transition surfaces. The method reduces tool wear and is cost-effective.
