Abstract：

The main reasons producing ridge defects of outer plate parts for automobile are the defects produced in the design and production processes. The design defects are mainly small inflection point and large contrast, etc., and the defects in the production process are mainly produced by poor precision of die surface and uncoordinated grind and assemble standards, etc. In order to eliminate the above ridge defects of outer plate parts, through methods such as CAE analysis, fine die surface design, manufacturing process optimization (such as dynamic measurement, benchmarking), fine grind and assemble (reasonable polishing methods and techniques) and fine adjustment (Audit review), the problems of unclear ridge, ridge displacement and repeated rectification could be eliminated in the manufacture and debugging process. Thus, the debugging difficulty and cost are reduced and the production cycle is shorten to ensure a clear, smooth and polished ridge. In addition, it is an effective way to obtain an outer plate forming die with high-quality.
