The multiple axis flexible CNC riveting cell consists of three major systems: a multi-axis part positioner, a multiple head drill and rivet machine and a multi-bowl rivet feed system. The CNC positioner has six axis of control; the five common axis of X, Y, Z, Alpha, and Beta plus tool position on the lower ram. The four function rivet head contains a drill spindle, a sealant applicator, a rivet insertion station and a camera unit. The unique lower ram will allow the machine to fasten high curvature parts as well as flat panels with minimal changes. The fastener feed system utilizes a bank of vibratory bowls that feed fasteners through a single feed tube. The fasteners are allowed to tumble and then are aligned prior to insertion into the anvil fingers. Countersunk fasteners as small as -4-3 will be fed by the system. The system will be used by Raytheon Aircraft Corporation to produce body panels and wing parts for the JPATS Program (Joint Procurement Aircraft Training System).

A drill and rivet machine with a unique dual lower ram has been designed and built. The dual lower ram assembly consists of two horn shaped rams that are mounted at ninety degree angles to one another. Both rams remain operational at all times. When one ram is in place in the front of the machine the other ram is pivoted out to the side of the machine. Each ram has a unique horn shape and carries its own offset lower anvil assembly. The unique horn design allows the ram to reach into high curvature leading edge parts. The operator can select either ram so that a complete ship set of high curvature parts can be produced by the machine with no other tool changes required.
