过程能力指标(Process Capability Index)是通過一個简洁的数值,用来表示过程符合产品规格之能力,是六西格玛的主要工具之一。 这个数值也表达了工序在一定时间里,处于控制状态(稳定状态)下的实际加工能力。它是工序固有的能力,或者说它是工序保证质量的能力,是现代企业用于表示制程能力的指标。指标的数值可视为过程之潜在能...
Cp and Cpk are commonly referred to as process capability indices. They are statistical measures used in process capability analysis to evaluate the ability of a process to produce output within specified limits. First, let's understand what Cp is. Cp, orprocess capability, is the ratio of the...
“Process capability is a prediction of future performance of the process. It can be stated as the range of outcomes expected for any measure of interest. Before considering capability, the process for the measure of interest must be stable (no special causes). This gives us a...

Cp and Cpk should be close in value to Pp and Ppk. If Cp and Cpk are much greater than Pp or Ppk (33% greater), your process may not be stable enough to conduct a capability analysis. Use control charts to evaluate the stability of your process. Stop...
