Process Capability过程能力
Process Capability is a statistical measure of how well a process output fits within customer specification limits, commonly expressed through indices such as Cp and Cpk. In manufacturing documentation, it appears in quality reports, control plans, and capability studies that evaluate whether a process can consistently meet tolerance requirements for a given characteristic.

Where this term appears
Translators encounter process capability in SPC reports, customer quality submissions, and first-article documentation prepared for engineering review. The text may include formulas, tolerance limits, and phrases like “capable,” “not capable,” or “Cpk target” inside quality dashboards and reports; translators need to keep statistical terms consistent so that quality conclusions are not altered.
Translation checks
A common error is translating Cp and Cpk labels as “process capacity,” which suggests maximum throughput rather than variation relative to specification limits. Another mistake is mixing up Cpk and Ppk or dropping the “k” index explanation, which can change whether the analysis refers to short-term capability or long-term performance.
Keep the term aligned across your files
