Abstract: Provided is a bilateral ultrasonic rolling processing track coordination method for a blade surface, the method comprising: step S1, performing layering processing on a blade to acquire a contour curve of “A”-shaped and “n”-shaped blade edges of a blade model at different heights; step S2: determining the endpoints of a blade processing track; and step S3: planning the thickness and the rotation angle of the blade, comprising: step S31, solving a main direction angle αmain of the contour curve; step S32, solving the thickness d of the blade; step S33, solving a rotation angle required by blade processing when the blade edge is “A”-shaped; and step S34, solving the rotation angle required by blade processing when the blade edge is “n”-shaped. According to the method, blade deformation generated by an ultrasonic rolling force is reduced, the processing efficiency is improved, and the blade processing precision is also improved.
