| description | The present invention relates to a surface treatment apparatus and method for inducing compressive residual stress in the surface of a workpiece with dimensional variations. The method comprises the acts of measuring the dimensions of the workpiece during a surface treatment operation and adjusting the surface treatment process parameters to account for the measured dimensions. In one embodiment, the apparatus comprises two surface treatment elements oriented in opposition to one another in a caliper configuration. The surface treatment elements are positioned and impinged against the surface of a workpiece by an actuator controlled by a computer control unit. The depth to which the surface treatment elements are impinged is precisely controlled to achieve the desired magnitude and depth of compressive residual stress. A sensor operatively connected to the apparatus senses and relays the dimensions of the workpiece to a computer control unit that adjusts the operating parameters accordingly. |
