摘　　要：多品种、小批量、短周期的生产模式已逐渐成为现代企业生产方式的主流。针对阀杆的技术要求以及工艺流程的分析,结合现场加工过程的历史数据寻找阀杆的关键质量特性,并对关键工序实施质量控制。应用贝叶斯预测理论的动态质量控制方法对具体加工过程进行监控以及分析过程能力,分析加工过程中的问题,提出了改进方案,取得了预期的效果,不仅使得阀杆的加工过程没有受到外来因素的影响而处于受控状态,而且它将为其它加工过程的质量控制提供重要的指导。这将有力的保证企业的产品质量,提高顾客满意度,降低成本,保证交货期。In manufacturing,diversification,small batch,short cycle of production mode has gradually become the mainstream of modern enterprise production mode.According to the technical requirements of stem and process analysis,combined with the process of historical data for the stem the key quality characteristics is searched,and quality control for the key procedure is implemented.By applying dynamic quality control method of Bayesian theory the specific process is monitored and the process capability is analyzed,and the problems occurred in the process is analyzed as well.Then the improved scheme is put forward to acquire the desired effect,preventing the stem machining process not only from impact of external factors under control,but also provides important guidance for other processing quality control,which guarantee the product quality powerfully and improves satisfaction of enterprise customer,reduces cost,and guarantee the delivery.
