Task -
Devise method of improving the accuracy of a 20-year-old positioning system used as part of an automated
fastening system. Upgrade control systems and rebuild riveter assembly. Provide means of ensuring contoured
skin panel is held perpendicular to riveter head without making contact with the part. Improve rivet installation
consistency by providing electronic adjustment of cycle parameters.

Solution -
A completely new C.N.C. system was designed and installed. An Allen Bradley 9/260 was selected along with an
SLC 500 dedicated to the riveter function control. Allen-Bradley CVIM vision system was integrated with a camera
on the lower anvil of the machine to be used for tack fastener resynchronization. Custom vision software allows
part features to be detected and part program data adjusted based upon the orientation of the feature found.
Servo control of rivet upset allows for numerical adjustment of the upset height attained. Ultrasonic sensors at
the machine head feed back signals to the C.N.C., which automatically adjusts the appropriate axes to maintain
level without making contact with the part.
