Two Automated Electromagnetic Riveting Assembly Cells (AERAC) were manufactured for Textron Aerostructures by Electroimpact, Inc. The AERAC installs the final rivets in the A330/A340 upper wing panel in the floor assembly jig. At Textron for each wing the corresponding floor assembly jigs for each wing are lined up end to end.
An operating procedure in which the formboards are removed in bays allows efficient operation of an in the jig riveter such as the AERAC. Specialized machine codes developed for the AERAC allows quick fully programmed stringer to stringer jumps of the stringer side offset tooling.
The AERAC is programmed entirely from a CATIA drawing of the part. Of the 5 axes of rivet data available only two are retained for use by the AERAC.
