The AIAG P/T is very simple. Mathematically, it is expressed as the following: P/T=(6σe)/(USL-LSL) where USL is the upper specification limit and LSL is the lower specification limit. The measurement standard deviation is multiplied by 6; this gives the "spread" of the measurement error. This "spread" is then … See more One reason we take measurements is to see if our product is within specifications. Consider the following two scenarios: 1. You take a sample from your process and measure it. The result … See more 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 … See more This publication examined two methods for determining the P/T ratio: one from AIAG and one from Dr. Wheeler. AIAG's method simply calculates a ratio of the measurement error spread to the tolerance and places … See more The approach below is described in detail in Dr. Wheeler's book EMP III, Evaluating the Measurement Process and Using Imperfect Data. If this book is not on your bookshelf, it should be. Dr. Wheeler's approach to P/T is to … See more WebJan 1, 2004 · Tech Tips. 1. If measurement variation can be reduced and GR&R ratios improved, there is a better ability to differentiate between parts that are in or out of. specification. 2.

WebJan 3, 2006 · The biggest difference is you use a known standard part instead of actual production parts, and you find the total variation by 3 people each measuring the known standard 7 times. You find the average and standard deviation of all 21 measurements, and to find the P/T ratio, all you do is: P/T = ((5.15*StDev)+ ABS(Known Standard - AVG)) / … 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.
