1. A machining path coordination method for bilateral ultrasonic rolling of blade surfaces, comprising:
Step S1, layering a blade to obtain contour curves with shapes of “A” and “n” of blade edges at different heights of a blade model;
Step S2, determining endpoints of machining paths of the blade;
Step S3, planning blade thickness and rotation angle, which comprising:
Step S31, obtaining main direction angle αm of the contour curves;
Step S32, solving the blade thickness d;
