Title: DNC/CNC Riveting Cells Applied in the International Aircraft Industry
text: During the past decade, the number of implemented DNC/CNC Riveting and Assembly Systems has substantially increased and new applications have been introduced into areas where only manual or semi-automatic assembly was once considered. The main reason for developing these systems was the increasing demand for a better level of quality and higher production rates. This paper describes new upper tooling conceived as modular building blocks used on C-frame riveting machines. In addition, applications of C-frame riveting machines for the automatic assembly of pressure bulkheads and freight room-/passenger doors are discussed. Other applications described include the automatic floor grid assembly of large commercial aircraft.
