Remanufacturing strategies not only provide the means to save materials from disposal, but also reduce the virgin material requirements thereby diminishing potential upstream impacts of material extraction and processing. In the aerospace industry, remanufacturing of aero-engine components can be profitable since they are made of expensive materials and have high added value. Differing from manufacturing process, remanufacturing processes present a number of special problems in operational and technological issues. This paper focuses on the repair technology that plays an important role in restoring worn parts back to their original as new condition. This paper proposes an adaptive repair system to solve the key problem of part-to-part variances in component geometry. A four-layer repair system structure is discussed and three key models that are used for system implementation are described.
