Patent ID: 7900351

Claim:
A method for manufacturing a gas turbine rotor having an integral blading, comprising the steps of producing unmachined rotor blade parts, the step of producing including: separating raw rotor blade parts out of a strip-shaped or band-shaped material of substantially uniform thickness and, thereafter, cambering and twisting said raw rotor blade parts to produce the unmachined rotor blade parts, each of the unmachined rotor blade parts having a substantially uniform thickness and a desired three-dimensional twist; joining at least one of the unmachined rotor blade parts to a rotor carrier; machining the at least one of the unmachined rotor blade parts attached to the rotor carrier to a nominal shape of a rotor blade, and thereafter, finely machining the at least one of the unmachined rotor blade parts to end contours of the gas turbine rotor having the integral blading.
