ABSTRACT:
A method and an apparatus for performing the method of inducing compressive residual stress in blading members integrally formed with a rotor. The method includes using a caliper-type burnishing tool such that the caliper arms of the tool are contoured and oriented for placing the burnishing elements on opposite sides of the blading member to be treated. The blading member is burnished to introduce a pre-determined pattern of residual compressive stresses in a selected area of the blade.
