What does a Gage R&R study primarily evaluate in a measurement system?
Answer: Repeatability and reproducibility of measurements
A Gage R&R study specifically assesses repeatability (variation from the same operator measuring the same part) and reproducibility (variation between different operators).
In an MSA, if the %Study Variation for repeatability is 45%, what is the most appropriate action?
Answer: Improve or replace the measurement instrument
High repeatability variation (above 30%) indicates the instrument itself introduces excessive variation and should be improved or replaced.
Which type of measurement system error is indicated when measurements consistently read 0.05 units higher than the true reference value?
Answer: Bias error
Bias is the systematic difference between the average measured value and the true reference value across the measurement range.
What is the minimum number of distinct categories (ndc) recommended by AIAG for an acceptable measurement system?
Answer: 5
The AIAG MSA manual recommends a minimum of 5 distinct categories to indicate the measurement system can adequately distinguish between parts.
During a linearity study, what condition is being assessed?
Answer: Whether bias remains constant across the full operating range of the gage
Linearity evaluates whether the measurement bias changes across the expected operating range of the measurement instrument.
In a crossed Gage R&R study using ANOVA, which interaction effect is analyzed?
Answer: Operator × Part interaction
The ANOVA method in a crossed Gage R&R analyzes the Operator × Part interaction to determine if certain operators measure specific parts differently.
