Abstract：

Based on ANSYS/LS-DYNA platform, the incremental forming process of the hemispherical workpiece was simulated. According to the simulating results of one-stage, two-stages, three-stages and four-stages forming path, the influences of different passes on wall thickness were analyzed. In addition, the simulating results of two forming sequences, top-down and bottom-up were compared to study the influence forming pattern for wall thickness. Thickness uniformity was taken as the principles to design the path of the hemispherical workpiece, and finally the optimal path was given. Experiment was also taken to verify the path.
