In a balanced Gage Study, each operator will measure the same number of parts the same number of times.

WebUse Nested Gage R&R Study to assess the variation in your measurement system when every operator cannot measure all parts. For example, you have 3 operators and 15 parts. Operator A measures parts 1–5 twice, Operator B measures parts 6–10 twice, and Operator C measures parts 11–15 twice. WebCrossed vs. Nested Designs • In crossed designs we assume that each operator can measure the same parts that other operators can measure. We also plan on having each operator measure the same part more than once. Why? • In nested designs, we assume that each operator measures unique parts. Operators will measure the same part more …
