浅析发动机制造业机加线SPC质量控制系统

A Brief Analysis of SPC Quality Control System in Engine Manufacturing

主要阐述了发动机机加线实行SPC质量控制图的流程,从制定产品的管控特性、控制图的选择、抽样原则的确定、控制线计算以及后续持续改进过程等几个方面进行了简单介绍。SPC质量控制图的实施可以及时发现并消除异常点,提前预防产品超差,降低生产不合格件加工风险,提高产品下线合格率。

The process of implementing SPC quality control chart of engine machine line was described,the procedure how to choose the control characteristic,the selection of control chart,the sampling principle,the determination of control line and the process of continuous improvement were introduced.The implementation of the quality control chart can find and eliminate the abnormal points in time,prevent the rejected products in advance,reduce the risk of machining defective parts,and improve the qualified rate of the products.
