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 smallbatch experiments.
