Today's aircraft final assembly takes place in rigid assembly lines and with the help of massive fixed fixtures. Measurement technology is usually used in isolation at individual assembly stations. Smaller batch sizes therefore require more flexible solutions in aircraft final assembly in order to be able to carry out reconfigurations in assembly more efficiently.
The aim of the iVeSPA research project is to develop a global reference system for the factory-wide provision of geometric measurement data in aircraft final assembly in order to provide the infrastructure for efficient reconfigurations of the assembly system and automation solutions.
Initially, the requirements of the measurement systems to be used with regard to relevant assembly processes will be determined. This is followed by a systematic evaluation of the measurement systems and a modelling of the measurement uncertainty and visibility. The models are integrated into a simulation environment in order to validate the measurement systems and measurement system combinations a priori for relevant assembly processes.
In a demonstration process, a global reference system will be implemented and appropriate measurement methods developed to capture relevant geometric degrees of freedom of the assembly units.
An algorithm is developed to test process reliability, which evaluates the geometric measurement data, performs a tolerance adjustment and returns control variables to the assembly site. The transmission of the measurement data is to take place via uniform interfaces and a superordinate communication platform (quality management system).
As a result of the research project, the principle of the global reference system can be demonstrated on a demonstrator. The tools developed, such as the systematic selection of potential measurement systems and a simulation environment for safeguarding new processes, can be used for transfer to industrial practice.
