An adaptive repair surface modeling approach for worn blades

Currently, worn blade repair work, obtaining the target surfaces manually wastes too much time. To improve repair ability, an innovative adaptive repair strategy is proposed which covers pre-inspection, welding, and machining process. Different from finding repairing surface manually, the welded surface and machining surface are restructured with less manual intervention. The welded surface ensured enough material for subsequent machining is captured by extracting upper profile boundary surface of its design one. Furthermore, a target machining surface satisfied design requirements, machining allowance, and geometric continuity is restructured using an effective optimization method. To prove the availability of the proposed method in this paper, a compressor blade repair instance, including welded surface and machining surface optimization and simulation is demonstrated at last.
