摘要： 结合数理统计学和稳健设计理论，对特征件冲压成形过程进行基于材料性能波动统计学分析的稳健设计，以整体质量工序能力指数Cpk和废品数为指标而获得稳健工艺参数，并通过小批量实验加以验证.结果表明，考虑材料性能波动的稳健设计可以有效降低批量生产的质量波动，从而降低废品率.

Abstract: The statistic analysis and robust design theory were combined to study the selection of robustness process parameters for a characteristic case stamping based on the statistic analysis of material properties’ variation. The derived robust parameters were obtained according to the best quality control exponent (Cpk) and lowest wastes. The parameters were verified with the smallbatch experiments.
