When the complexshaped sheet metal parts were formed by the doublesided CNC incremental forming, there were multiple tool head function assignments and forming sequences. For the sheet metal parts with the embedded bidirectional convex features, according to the convex direction of the features to be formed, two kinds of forming sequence were proposed, and the corresponding tool paths were generated. Then, the forming processes based on the two forming sequences were simulated numerically by the finite element analysis software ANSYS/LSDYNA, and the thickness distribution of the formed part was given. Furthermore, the contour curve and the deviation curve of the formed part and the designed part were plotted, and the influences of the two forming schemes on the forming precisions were analyzed. The finite element analysis result shows that the different forming sequences have different influences on the forming quality, and the forming scheme of the first positive and then negative can obtain good contour accuracy, which is closer to the outline of the designed part. Thus, designing the reasonable forming sequence can improve the forming precisions effectively.
