Abstract
The regeneration of aircraft engines provides a key approach in order to reduce operating costs of these complex capital goods. The efficient and resource-saving maintenance of aircraft engines is particularly challenging, as they are made from a variety of different parts with locally adapted properties and different functionalities, which therefore also differ in the requirements in surface quality. The engine parts are manufactured and repaired on different machines, such as milling or turning machines. The subsequent quality check is realized with the help of highly specialized metrology systems. In case of so-called aircraft blisks, tactile coordinate measuring machines are used to measure the blisks surface data in regions with limited accessibility. The state-of-the-art regeneration procedure is therefore time-consuming and costly, as the parts need to be moved and mounted several times. In this paper, we present a blisk regeneration approach, which is meant to allow the inline quality monitoring of the regeneration process within a milling machine by means of a rigid endoscopic fringe projection system. The presented approach is meant to be time- and resource-saving as the fringe projection system is directly used in the blisk repair environment. To this end, we present the developed measurement system, outline the planned system integration into the milling machine and define challenges that arise due to the calibration of optical measurement systems within the production environment. The borescope with a chip-on-the-tip camera at the measuring head offers the possibility to drive into limited space and to perform high-precision 3-D measurements.
