This necessitates to repair such defects as soon as possible. As it is time-consuming and costly to disassemble the entire engine to access the compressor blades, it can be advantageous to perform such repairs on-wing, while the engine is still assembled. The main challenge in machining compressor blades on-wing is the limited accessibility within the engine, which precludes the use of traditional machining tools and demands the development of new solutions. To address these obstacles, this work proposes a flexible simulation framework including a shape optimization technique to aid in the development of suitable robotic kinematics for space-constrained machining tasks. Further simulation functionalities such as an interactive mounting simulation foster detailed feasibility studies of kinematic concepts.enhttps://creativecommons.org/licenses/by/4.0/SimulationRobotic machiningOn-wingMROForeign object damageTechnology::629: Other Branches::629.1: Aviation::629.13: Aviation EngineeringTechnology::629: Other Branches::629.8: Control and Feedback Control Systems::629.89: Computer-Controlled Guidance::629.892: RobotConference Paper10.1007/978-3-031-91463-8_3010.15480/882.18966
