For a stamped part, excess material on the edge need to be cut to get the final part. To explore the impact of different laser-cutting paths on the accuracy of part formed by multi-point forming with blank-holder, three different cutting paths are designed in this paper, and the process of laser-cutting is simulated by finite element method. By comparing the springback of the parts under different cutting paths, it is found that the part cut by path 3 has the highest accuracy. Finally, the experiment is performed with path 3 and compare the shape of the formed part with the target part, it is verified that cutting with path 3 can obtain higher precision parts.
