Take relevant process information for a process using discrete data. Calculate process assessment measurements. Look at a powerful operation metric called Rolled Throughput Yield.
WebWhen calculating Cp you divide the specification range by six sigma. This is plus and minus three sigma on each side of the mean of the process which would include about 99.7% of the distribution of output if the process is normal. Cp considers only the spread and not the centering of the process. Web并且说明，Cp, Cpk的计算是基于普通原因影起的变差（用组内标准差去估计）与规格限之间的关系，它能用来对过程进行预测，而Pp, Ppk是用所有个体数据合在一起来计算的整体标准差去估计，它对于预测未来没有什么作用。 我们用例子来说明AIAG的理论，如上面这两张图，我们把过程随时间的分布情况描述出来，最终结果分布用蓝色来表达。 对于Cp, Cpk …
