99.5% - Quality Inspection Requirement (Power / Sample Size Selection)

E

Hello everyone,

I would like to know if there is a way to calculate the Sample Size, based on target power levels (like 95% Confidence) for Attribute Inspection data with a Goal = 99.5% Quality.

We are wanting to calculate an OEE metric for a piece of Automated Assembly for Spring Assemblies. Our feeling is that a 200 piece sample is adequate to determine this level of Quality %, but I would like to have some tool to calculate this or a formula.

Does anyone know anything exsists to determine appropraite sample sizes, based on power assumptions and acceptable quality levels???

:bonk: Any information would be GREATLY appreciated. :whip:

Thanks!!!!
