The ANOVA method doesn't take the feature specification / tolerance into account when determining the % GR&R. Why? I performed na ANOVA GR&R for a production burst test stand and got a GR&R of 96%. When the same data was put into the avg. / range form with the specification of 98psi to 250psi I got 29%. It seems to me that this could be huge in determining if the measurement system is truly acceptable or not for the product. On top of all of this, the results are not really the weld joint failing but the parts parent material breaking apart. Just trying to learn more about ANOVA method and when / how to apply it. Thanks.
