This technical paper will address advancements in automatic riveting machine design, control, and process. VME based motion control combined with new component designs have produced a very flexible, state of the art, riveting system. This flexibility allows use of the fully programmable squeeze/squeeze III slug process, and variable upper tooling clearance heights to decrease cycle times. This state of the art technology includes infinitely positionable high speed double acting servo pressure foot, drill and shave spindles, upper buck cylinder, lower ram, and lower clamp assemblies.
