摘要: Vibration finishing can effectively reduce the surface roughness of blisks and change blade shape accuracy. This study investigates the influence of vibration finishing on the shape accuracy of the blade part of the blisk. The influence of the fixed attitude of the blisk on the position accuracy and profile accuracy of different measuring sections of the blade is analyzed. The changes in the blade geometry before and after vibration finishing are analyzed. The adjustment method of blade disc attitude in the machining process is developed, and the tooling used to fix the blade disc in the vibration finishing is improved. By controlling the deformation in different time periods to offset each other, the contact between the abrasive and the blade edge is reduced, effectively reducing the displacement of the blade section and the excessive wear of the edge.
