Abstract：

Traditional simulation of incremental forming takes a long time, which is difficult to effectively guide the actual process development. Therefore, based on software platform AI-FORM independently developed in China, a virtual multi-tool algorithm was developed to realize the rapid simulation of incremental forming. Then, by carrying out the integrated simulation process of modeling-path design-simulation-optimization for typical pyramid part, the profile accuracy, thickness difference and simulation time difference between single-tool and multi-tool simulation results were compared, and the efficiency and reliability of the virtual multi-tool algorithm were verified. Furthermore, combined with the actual production requirements, the virtual multi-tool algorithm was applied to the simulation of the incremental forming process for saddle-shaped connector, and the machining path was optimized through feature partition and curve recognition. Finally, the rationality and necessity of the path optimization design were proved by comparing cross-sectional profile and feature area thickness between the actual test part and the simulation results, and the accuracy of the virtual multi-tool algorithm in predicting the forming of actual part was further verified.
