Bombardier Canadair was the first airframe manufacturer to take advantage of Gemcor's “state of the art” All Electric Rotary Head fastening system. Due to the success of the first 2 systems installed at Canadair, they have purchased 2 additional for a total of 4 systems in use. See figure 1. This paper will act as a case study on how Canadair has taken advantage of the very fast cycle times combined with greater flexibility and quicker set-up times than on existing hydraulic machines. Significant increase in fastener installation process quality indicates this is now the standard that all automatic fastening machines shall be measured against.

This technical paper will address the advancements made in the area of automatically riveting complex double-contour 180 degree fuselage panels. Detailed is an automatic fastening system that accomplishes the aforementioned task in a single workframe mounted panel/fixture sequence. Through the use of innovative machine motions and enhanced adaptive controls, increased production throughput for difficult to rivet panel assemblies has been realized.
