Control feedback loop for real-time variable needle peen forming

摘要

CONTROL FEEDBACK LOOP FOR REAL-TIME VARIABLE NEEDLE PEEN FORMING Method and apparatus are provided for processing and changing the physical characteristics of a metal workpiece into a final metal component. Predetermined processing parameters are established for achieving a final metal component. The metal workpiece (W) is positioned securely on a support (202) during the changing of the physical characteristics. Impacts are applied to a surface (206) of the workpiece multiple times for achieving the final metal component while controlling the impacting with the predetermined processing parameters. A sensor is provided for continuously sensing the currently existing physical conditions of the workpiece during impacting. The predetermined processing parameters are changed into adjusted processing parameters and the impacts are changed in reaction to the currently existing physical conditions of the workpiece from the sensing and processing of the workpiece until the final metal component has been achieved.
