Abstract
A distortion correction tool corrects distortion in a workpiece held by a fixture. Sensors in the fixture determine the existence, extent, and location of distortions in the workpiece and a controller directs the application of the distortion correction tool to the workpiece based on the information received from the sensors. Particularly, a ram mounted to a quick-change tool head for a robotic arm is used as a distortion correction tool to correct distortions in a workpiece by inducing plastic deformation through use of compressive force, the extent and location of which is determined by a controller based on sensor measurements.
