Determinate Assembly of Tooling Allows Concurrent Design of Airbus Wings and Major Assembly Fixtures 2004-01-2832

Most new aircraft programs encounter the challenge of balancing the time required for design optimization with product delivery constraints. The high cost and long lead times of traditional tooling makes it difficult for aircraft manufactures to efficiently meet ever-changing market demands. The large size, low relative stiffness and high positional tolerances required for aircraft components drive the requirement for rigid fixed tooling to maintain the precision part relationships over time. Use of today’s advance 3-Dimensional CAD systems coupled with the high accuracy of CNC machines enables the success of the determinate assembly approach for aircraft tooling. This approach provides the aircraft manufacturer significant lead-time reductions while at the same time it supports enhanced system flexibility. Determinate assembly for aircraft tooling has been proven to be high successful for tooling manufacture on large-scale system such as the A380 and A340–600 wing assembly projects.
