Abstract
The profile accuracy and surface quality of repaired blade are directly determined by the dimension restore, which has a far-reaching impact on the service performance and fatigue life of engine after maintenance. In this paper, the robot belt grinding method for repairing blade is studied. A flexible grinding method with variable stiffness is proposed to realize the rapid and accurate material removal and the improvement of the surface quality of the repaired blade. The method of model detection and processing of the repair sample is studied, and the machining accuracy of the grinding device is improved through robot operation calibration. Finally, the feasibility of the above method is verified by the grinding experiments of the samples of the profile repair, edge repair and blade tip repair. The grinding accuracy can reach 0.07 mm, the surface roughness less than Ra0.04.
