| Abstract: | Calculating and evaluating process capability indices are very important for process quality analysis and control, and they are also included in CAQ as a key module. The paper presents some real problems in calculating process capability indices. Based on these problems, the paper puts forward how to get a rationale sample, the effects of non-normal data, and the relationship between the confidence interval of C_p and sample size. The purpose of the paper is to provide some guidelines for quality engineers to conduct process capability analysis in their workplace. |
