Web解析：CPK=(1-CA)*CP=1/3δ 所以Ca=0.442 δ=0.92*3=2.96; ca 值的意义, 在於差距值和公差值的比率, 若是差距值和公差值一样, 就代表完全偏离, 也就是100%偏离;而偏离一半就是 50%, 再来就是 25%, 然後 12.5%. 最後 6.25%. 很明显，Ca=44%,偏离目标太远。 WebCpk can never exceed Cp, so Cp can be seen as the potential Cpk if the overall average is centrally set. In the example, Cp is 1.17 and Cpk is 0.67. This shows that the distribution can potentially fit within the specification. However, the overall average is currently off center.
