Gauge capability index

WebOnline Professional Certifications Training Provider GreyCampus WebMost research works related to process capability indices assume no gauge measurement errors. However, such an assumption inadequately reflects real situations even when advanced measuring instruments are employed. If we do not take into account these errors, conclusions drawn from process capability are therefore unreliable.

WebJul 16, 2010 · For example, say a capability study with a desired target of 1.67 or greater has yielded a failing C p of 1.54. The team would compare this to the Douglass Index conversion table to learn if the R&R rate is 25 percent or less. If so, the index converts the former failing C p of 1.54 to an improved 1.67 (Table 2).
