Aircraft engine blades are subject to damage because they are constantly exposed to high temperature, pressure and speed. Since the technology of repairing the damaged blades has been dominated by foreign companies, domestic airlines have to invest a tremendous amount of cost and time in having damaged blades repaired. This paper is to put forward a method in an attempt to remanufacture and repair damaged blades. Firstly, we evaluate the possibility of repairing the damage by analyzing the characteristics of damaged blades. Secondly, we acquire and process the point cloud of broken blades, extract the boundary curve of the blade section, reconstruct the 3D digital models of blades and obtain the 3D object model of blade via Boolean operation. Thirdly, we repair and remanufacture the damaged blades via laser cladding and adaptive machining. Finally, we check the precision of the 3D digital model and perform an error analysis. The results turn out that the proposed 3D digital model is of relatively greater accuracy and smoothness and remanufactured blade can meet the technical requirements prescribed in the aircraft engine maintenance manual.
