This paper is focus on two-Pass Deep Drawing Forming of conical axisymmetric parts, study on the finite element simulation and test of multi-Pass deep drawing part. It carry on the finite element analysis and calculation using the ANSYS/LS-DYNA software platform, analyzing the simulation results such as stress , strain distribution and formability by post-processing LSPOST software. It was done multi-Pass deep drawing test using a set of combined type mould. Based on the multi-Pass forming test by using a set of combined type mould, comparison of simulation and test data can be obtained through the forming limit diagram. The result of simulation and test is basically the same and both reflect the formability.

Forming limit diagram is often used as a criterion to predict necking initiation in sheet metal forming processes. In this study, the forming limit diagram was obtained through the inclusion of the Marciniak–Kaczynski model in the Nakazima out-of-plane test finite element model and also a flat model. The effect of bending on the forming limit diagram was investigated numerically and experimentally. Data required for this simulation were determined through a simple tension test in three directions. After comparing the results of the flat and Nakazima finite element models with the experimental results, the forming limit diagram computed by the Nakazima finite element model was more convenient with less than 10% at the lower level of the experimental forming limit diagram.
