Metrology has multiple applications in sectors other than the aerospace, such as automotive or energy. It is not only useful to make manufacturing processes more accurate, efficient, cost-effective and productive but also to detect anomalies in quality controls. It also has several applications in the aviation industry. Airbus uses tools like photogrammetry, laser tracker or laser radar to analyse their wings during inspection tasks or manufacturing process. Airbus has also incorporated this feature on the final assembly line of the Airbus 380. In this case, the operators make sure that the fuselage, which is formed by three different sections, is well assembled. The assembly process is followed through all the steps to ensure that all components are aligned properly. Boeing has also automatized data acquisition for part fit-up and optimal airplane sections joints on the Boeing 787. In aviation, there is the need to guarantee all aircrafts in service meet design requirements. There can be serious consequences if components are not aligned properly or the performance can be compromised. For this reason, the analysis of the plane’s structure has always been a need. ATR relies in metrology to analyse the aircraft’s structure after incidents in service (e.g. hard landing) or in the final assembly line if any anomaly is detected during the quality control check-ups. The main objective of this project is to optimise the current procedure in order to reduce time and increase precision; it is inspired by the DMAIC 6 sigma methodology. This project explains, in chronological order, the steps taken to improve the 3D Measurement Analysis method used at ATR. The first phases consisted on defining the current procedure and finding possible areas of improvement. Then, several solutions were designed and implemented.
