Abstract:
The state of the art inspection method for cracks in aircraft engine components in the aviation Maintenance, Repair and Overhaul (MRO) industry is the knowledge based Fluorescent Penetrant Inspection (FPI).It is usually executed manually. This method is on the one hand very reliable regarding the detection probability of cracks, but on the other hand time intensive and the quality of the result is dependent on the particular expertise and condition of the executing worker. This paper introduces a fully automatic and robot guided white light interferometry (WLI) as a future crack inspection system. The focus is set on the adaptive component of that inspection process. Chapter 1 gives a short introduction to the different inspection technologies. In chapter 2 and 3, the overall inspection system setup with the different measuring devices and the inspection process steps are presented. Chapter 4 contains a comparison of different adaptation strategies and focuses on the strategy implemented in the given system. Chapter 5 is a conclusion in which a brief overview of the future work is given.
