The invention provides a debugging method for controlling a stamping slip line, and belongs to the technical field of automobile stamping. The debugging method comprises the following steps of determining the stable state of a stamping part with slip line defects according to the slip line defect position and the slip line defect degree of a stamping part; obtaining reasons for generating slip line defects of the stamping part, and determining a debugging method; determining a debugging sequence according to the contribution degrees of various reasons of the defects; and adjusting and modifying a mold through the debugging method and the debugging sequence. According to the debugging method for controlling the stamping slip line, balanced feeding control and a uniform internal forming state in the stamping part forming process are effectively guaranteed, and generation of the stamping part slip line is effectively controlled, so that it is ensured that the single stamping part face product quality is reasonab
