Abstract
To achieve a build rate of up to 13 A350 XWB planes per month, a new way of using robots to insert stringers on CFP fuselage sections needed to be developed. Premium Aerotec identified that a manual process would not be able to keep up with this demand, so FFT-Edag Produktionssysteme was tasked to develop a turnkey solution for positioning these stringers. The final solution uses a 6DoF laser tracker to monitor the robot during its traversal over the stringers and immediately corrects any deviations compared to the 3D model. Two robots grip a stringer, move it to the semi shell and finally hold it just centimeters above the material surface. The CFP stringers used for the A350 are up to 18 m long. They must be positioned in the circumferential direction with a tolerance of +/- 0.3 mm and in the longitudinal direction with a tolerance of +/- 1 mm. This presentation will discuss the unique attributes of the system that was developed for this task as well as give some real world figures as to both the accuracies and productivity gains achieved by Premium Aerotec during production of these fuselage sections for the A350 XWB.
