As a quality control expert with extensive experience in statistical process control, I can provide you with an accurate explanation of the relationship between Cpk and Cp.
When Cpk (Process Capability Index) is equal to Cp (Process Capability), it indicates that the process is centered perfectly between the specification limits. This means that the process average is exactly at the midpoint of the lower and upper specification limits, and there is an equal amount of tolerance on both sides of the process mean.
In practical terms, a Cpk of 1 implies that the process is capable of producing parts or products that fall within the specification limits, but it is not necessarily efficient or cost-effective. It's also important to note that a Cpk of 1 does not guarantee that all parts will be within specification; it simply means that the process is centered and has an equal potential for producing non-conforming items on either side of the specification limits.
Now, let's translate this into Chinese:

When the average of the process approaches the target value, the gap between Cpk and Cp closes. When the average of the specification is equal to the target value, then Cpk is equal to Cp. Cpk can never exceed Cp. Both Cp and Cpk can be calculated with the generation of descriptive statistic views and histograms.
