The incorporation of split mandrel coldworking into a single- station, automated wing assembly machine advances the technical quality of automated production. Coldworking innovations, including the CMX process and new puller unit development, combined with new clamp-up technology, have eliminated the need for manual dissasembly and deburring, both costly and time consuming procedures. These advances in automation are illustrated in the development of a next-generation automated unit created for wing production of the Airbus A340-600 wide-body program. This paper describes the implementation of new fastener and coldworking technology that led to the development of this automated manufacturing system.
