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.

Web% Variance due to measurement system = 100(σ ms 2 /σ t 2) The gage R&R study focuses on σ ms 2. In a gage R&R study, you can break down σ ms 2 into its two components: Repeatability is the ability of the measurement system to repeat the same measurements on the same sample under the same conditions. It represents an assessment of the ... 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 …

WebThe total Gauge R&R variation, which includes all sources of measurement variation, is 1.34 cm wide. This is 44.53% as wide as the spec limits. This value is also reported as the precision to tolerance (or P/T) ratio, where precision is the total Gauge R&R variation and the tolerance is the width of the specs. Our P/T ratio is 44.53.
