  • Method and apparatus for imparting a simple contour to a workpiece
    Patent number: 4694672
    Abstract: An improved method and apparatus is provided for imparting a simple contour to an aircraft skin. A treatment chamber having a conveyor with a workpiece attached thereto and a shot peening blast unit positioned therein is provided. The workpiece is conveyed past the blast unit for peening treatment. A control system is provided for orienting the workpiece and blast unit so that the peening is done only in narrow spanwise strips and only on common chord percentage lines of the workpiece. This method and apparatus thereby creates chordwise simple curvature to the workpiece while minimizing compound curvature effects.
