摘要
应用六西格玛管理工具对高压开关铝及铝合金导体镀银的工艺过程进行研究,通过柏拉图、趋势图和二项过程能力分析对一次终检合格率进行分析,用因果图、因子矩阵分析、假设检验、失效模式分析对影响外观和结合力的因子进行区分,并对确定的关键因子采取改进措施,制定管理计划,修订工艺文件并标准化。经过10个月的持续改进,铝及铝合金镀银一次终检合格率稳定在95%以上,大大节约了制造成本。
The process of silver plating on aluminum and aluminum alloy conductors used for high-voltage switchgears was studied by application of six sigma management kit. The final inspection pass rate was analyzed by Pareto chart, trend plot, and binomial process capability analysis. The factors affecting the appearance and adhesion were discriminated by cause-and-effect diagram, factor analysis matrix, hypothesis testing, and failure mode analysis. The measures for improvement of key factors were determined. The management plan was developed and the process documents were revised and standardized. The final inspection pass rate is maintained at least 95% and the manufacturing cost greatly reduced after a 10-month continuous improvement.
