Gantry Robot Peening of Aircraft Engine Components

A Gantry Robot is integrated with part manipulation to peen critical surfaces on a variety of aircraft engine components. Venturi nozzles are used to cover large line-of-site surfaces. A rotating lance peens dovetails on fan disks. A 0.090 inch diameter lance is used to peen oil holes on shafts. The machine automatically shifts between three different media sizes. The shaded Almen strip method is used to determine Intensity for small lances.
