The present invention belongs to the field of blade repair processing, and specifically discloses a method, system, storage medium and product for decoupling the tool mark error during the repair of an integral blade disk, comprising: based on the tool mark error after the blade repair, determining the iterative function #imgabs0# of the actual undeformed cutting depth according to the fixed point iteration method: #imgabs1# wherein a k 、a k+1 are the actual undeformed cutting depths at the kth and k+1th iterations, respectively. e The target cutting depth, Δd, and f represent the tool mark error and yield deformation error functions. The iterative function #imgabs2# is solved using the Mueller iteration method to obtain the actual undeformed cutting depth a at which the iterative function converges. The workpiece positioning error and yield deformation error are then determined based on the actual undeformed cutting depth a, achieving decoupling of the tool mark error. This method significantly reduces the impact of positioning error and yield deformation error during blade repair, improves the accuracy of tool mark error compensation, and is applicable to various aircraft engine integral blade disc repair and compensation processes.
