摘　　要：通过六西格玛管理DMAIC(定义、测量、分析、改善、控制)流程并结合Minitab软件,对O形橡胶(氟硅橡胶)密封圈(简称O形密封圈)内径控制进行研究。通过试验数据分析得出O形密封圈影响因子最优组合,通过回归分析确定O形密封圈内径的关键影响因子,通过流程控制使O形密封圈内径合格率得到提高。By using the DMAIC(definition,measurement,analysis,improvement,control)process of six sigma management combined with Minitab software,the inner diameter control of rubber(fluorosilicone rubber)O-ring(referred to as O-ring)was studied.The optimal combination of the influence factors of the O-ring was obtained through test data analysis,and the key factors influencing the inner diameter of the O-ring were determined through regression analysis,and the pass rate of inner diameter of the O-ring was improved through process control.
