摘要：To solve the problem about the difference between the design shape and the actual after the sheet metal forming because of the springback, the stamping simulation software can be used to predict the springback values, and according the values, the shape of the die surface can be compensated in the opposite direction to make the forming part fit the design requirement. In the paper, according to the springback valves predicted by KMAS, the R、S and the triangular element coordinate mapping methods are put forward to amend the element node movement. And the amending nodes are used to build the CAD model, which can be the reference of the die surface. In the end, an example was shown to test the validity of the method.
