Abstract：

A two-pass incremental forming outer edge flanging path was designed and optimized by using the research method combining numerical simulation and physical experiment, and compared with the single-pass forming, it was applicable to a wider processing range. The research results show that the use of the outer edge flanging path with circular arc and straight line in two-pass incremental forming can process the flanging parts with larger blank diameters that cannot be formed in a single pass and improve the wall thickness distribution of workpiece, and the forming quality is the best when the processing diameter of the first pass is set to dm+(D-dm)/4. According to the finite element simulation experiment, the wall thickness distribution curve and the average wall thickness value of workpiece were analyzed, and the expression of the round hole flanging height for the two-pass incremental forming of reaming was fitted. Through the verification of physical experiments, the prediction of the outer edge flanging height in the two-pass incremental forming is realized.
