Development of Process Capability Table and its Application

공정능력지수표(工程能力指数表)의 개발(開發) 및 그 응용(應用)

Process Capability Index is defined as a ratio between predetermined tolerance and natural tolerance of existent process ($6{\sigma}$). And it is widely used as a performance measure for quality control activities, and a criterion for process classification. This paper developed a unity-fixed process capability table for convenience to calculate process capability and showed how to use it.
