Measuring System R & R analysis of the choice of sample size
And r on the repeatability error estimation. When the time given n and r,[link widoczny dla zalogowanych], m, the width of the confidence zone trends Q shown in Figure 1, with the measured increase in the number of the confidence interval narrowing. To maximize the effectiveness of measurement systems analysis, under normal circumstances,[link widoczny dla zalogowanych], should choose 3-4 surveyor, if the repeatability error is relatively large, the conditions permitting, may be appropriate to increase the measurement by the experiment.
