Abstract：

For CAS of car body exterior, the influences of different parting lines at CAS key areas on the quality of stamping parts were researched strongly, and the numerical model of CAD product for outer side panel was established based on CAS data of different parting line schemes. Then, the model of process scheme was established by importing data of outer side panel to software Autoform, and the multi-process stamping processes were simulated and analyzed. Base on the latest process scheme of Autoform simulation, the die of outer side panel was developed, produced and verified. Comparing the prediction of Autoform simulation and the result of die tryout, the advantages and disadvantages of different parting line methods were summarized, and the reasonable parting line and the boundary conditions were proposed. Thus, the quality problem of produced part at later stage caused by unreasonable CAS parting line was avoided, and the cycle times of design and manufacture were reduced to reduce the developed cost of vehicle type and provide the reference for shape design of new vehicle type.
