原文:In the case where the (higher order) measurement system used during buy-off has a GRR of 10% and the actual process Cp is 2.0 the observed process Cpduring buy-off will be 1.96;
原文:When this process is studied in production with the production gage, more variation (i.e., a smaller Cp) will be observed. For example, if the GRR of the production gage is 30% and the actual process Cp is still 2.0 then the observed process Cp will be 1.71
带入计算,Cp(观测)=2*(1-0.3*0.3)^0.5=1.907878(和这个1.71对不上...)
