Method and device for controlling edge effect of front edge of blade in impeller abrasive flow treatment process

In order to overcome the defects of the blade caused by the fact that the edge effect of the front edge of the blade is obvious compared with that of a blade body in the prior art, the roughness grade of the finished surface subjected to overall abrasive flow finishing treatment of the blade is low and cannot meet the requirement. In order to solve the technical problem that the quality of the blade front edge after finishing is easy to be out-of-tolerance when the blade front edge meets the requirement or the roughness grade of the finished surface meets the requirement, the invention provides the blade front edge edge effect control method and device in the centrifugal impeller abrasive flow treatment process, the flow field pressure of the blade front edge can be reduced, the edge effect of the blade front edge is weakened, and the blade front edge quality is improved. And the problems of blade front edge contour deformation, size out-of-tolerance, obvious microscopic dents and the like are controlled. The
