Bombardier faced new manufacturing process challenges drilling and fastening CSeries* aircraft panels with multi-material stacks of composite (CFRP), titanium and aluminum in which Gemcor responded with a unique, flexible CNC Drivmatic® automatic fastening system, now in production at Bombardier. This joint technical paper is presented by Bombardier, expounding on manufacturing process challenges with the C Series aircraft design requirements and Gemcor presenting a unique solution to automatically fasten CFRP aft fuselage panels and aluminum lithium (Al Li) cockpit panels with the same CNC Drivmatic® system. After installation and preliminary acceptance at Bombardier, the CNC system was further enhanced to automatically fasten the carbon fiber pressure bulkhead dome assembly.

This technical paper will address the introduction and development of the all electric riveting and positioning systems designed and manufactured at Gemcor. The industries desire to have reliable machines which are both clean (oil and leak free) and quiet while not compromising cycle rate were the driving force behind this development. The main topics of discussion will be the All Electric Space Shuttle Intertank Fastening System G86 and a design evolution to the new Multi-Flex configuration which is in the process of being delivered for a challenging airframe application (220 degree lobe riveting) with the majority of the focus on the advanced technologies developed for use in the upper and lower riveting heads.
