A method of designing a tool for forming a rotor blade including an airfoil portion includes generating a computer model of a rotor blade having an airfoil portion, and determining a curvature and radius of curvature at sections of the rotor blade. An inner and outer diameter of a circumferential forming portion of a tool operable to form the rotor blade may then be calculated. A method of designing a tool path for forming a rotor blade including an airfoil portion includes generating a computer model of a cylindrical tool operable to form a rotor blade including an airfoil portion and of a rotor having a plurality of the rotor blades. The computer models of the rotor and tool are used to generate a first and second tool motion corresponding to airfoil suction and pressure portions. A method of forming a rotor with integral blades is also disclosed.

An example peening tool includes at least one first roller having a peening surface disposed about and along a first core. At least a portion of the at least one first roller is configured to contact a component to be peened along a length. The length extends along at least a portion of the first core. The at least one first roller is configured to provide line contact on the component along the length. A profile of the at least one first roller is determined based on a profile of the component. The peening tool includes a backer disposed in register with the first plurality of rollers such that the first plurality of rollers moves with the backer during peening. The at least one first roller and the backer are configured to be arranged on opposing surfaces of the component. Peening models may predict peening parameters and controller settings.

A method for peening a surface of a material is disclosed. The method may include producing repeated, separated and high speed liquid drops and moving the liquid drops across the surface to be peened. The liquid drops are essentially free of air bubbles and the velocity of the liquid drops is at least 500 ft/sec. A peening apparatus to produce repeated, separated and high speed liquid drops is also disclosed. The apparatus may comprise a storage tank, a nozzle, a pump, an accumulator, a regulator and an actuator. The apparatus may control the volume and velocity of the produced liquid drops as well as the frequency of the liquid drop production.
