process capability index 예문

• The most common metric used is the process capability index C pk.
• A process capability index is used to indicate the relationship between tolerances and actual measured production.
• Since the process capability is a function of the specification, the Process Capability Index is only as good as the specification.
• By modeling the effect of production noise C p and C pk ( process capability index ) in production can be predicted.
• The ability of a process to meet specifications can be expressed as a single number using a process capability index or it can be assessed using control charts.
• The "'process capability "'is a measurable property of a process to the specification, expressed as a process capability index ( e . g ., C pk or C pm ) or as a process performance index ( e . g ., P pk or P pm ).
