The first step in doing simplified gauge verification is to get several "master" products near the product specification center. The supplier and customer must agree on the dimensions of these masters.
Masters can be quantified either by using outside firms that have calibrated specialized measuring devices or by getting mutual agreement between the supplier and customer (Figure 9-1).
The reason the gauge error includes the ± accuracy is that the tolerance, which is the reference, also includes the ± variation from process center.
Using one of the randomly picked "masters," have three inspectors (or operators) measure the master seven times each. Have them take the readings as if they were taking ...
