Barton, E., "High Performance Motion Control Without a Foundation For Fuselage Fastening Automation," SAE Technical Paper 2016-01-2103, 2016, doi:10.4271/2016-01-2103.
This technical paper details an optimized Drivmatic machine design delivered to a Tier 1 aero structure supplier to automate drilling and installation of rivets, hi-loks, lockbolts & swage collars for individual fuselage panel assemblies with high throughput & strict quality requirements. While certain robot solutions continue to be explored for specific applications at many Tier 1 aero structure suppliers, robot payload capacity has limitations beyond certain criteria, which often times point towards an alternative machine design as in this case study. A typical approach for adding more automation is to allocate shop floor space based on the solution’s foot print, however contrary to most approaches this solution had to be designed to fit within a pre-determined factory footprint over a geographic location with a high water table that would not permit a foundation. GEMCOR was therefore challenged to deliver a CNC automatic fastening solution with high-speed motion control technology that would accurately and reliably perform under higher speed conditions without a foundation.
