Webratio (P/T). Example Data The P/T often comes up as part of a Gage R&R analysis. Suppose we perform a Gage R&R analysis on a measurement system used in our process. We select 3 operators (A, B, and C) to be part of the study. We select five parts that represent the spread of the production process. Each part is measured twice by each operator. Web%GRR 是 GRR 跟 total variation 在標準差的比率(以%為單位），藉於這個比率來比較重複性跟再現性的變異與整體量測的變異，以評估量測系統的重複量測及再現性的能力。 理想上，量測的結果，來自量測系統本身的變異要越低越好。 AIAG 提供一個判斷 GRR 能力的一般 ...

WebIt is common to examine the P/T ratio which is the ratio of the precision of a measurement system to the (total) tolerance of the manufacturing process of which it is a part. If the … Web•The P/T ratio (called % Tolerance in Minitab) is the most common estimate of Measurement System precision – May be appropriate for evaluating Measurement System performance with respect to specifications – Specifications, however, may be too tight or too loose – Generally, the P/T ratio is a good estimate when the measurement system is … touche vatira rl
