Abstract：

A parametric CAE model of NC tube bending was established using PAM-TUBE 2G which is an excellent nonlinearity dynamic activity manager of tube forming . The validity analysis shows that the model could reflect the major physical laws of tube bending. Based on this model, the forming mechanism and laws of process parameters impact on the quality indexes were studied. Conclusions are consistent with the plastic forming laws and the recognized research findings.
