A method for producing a turbine root from a piece of parent material in which the turbine root has an engagement face with retaining elements for retaining the blade to a rotating member includes the steps of rough machining the root from the parent material by Electrical Discharge Machining (EDM) to issue a stock layer along the engagement face, electropolishing the root to remove the stack layer, and stress-treating the root to induce residual compressive stresses along the engagement face.
