| Abstract: |
| 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. |
