Gauge R&R Fully Explained!! (Measurement System Analysis) Part 1

Are you curious about how to perform a Gauge R&R? Or are you wondering WHY you should perform a Gauge R&R?
This video is the first video in a three-part video series where we will cover the entire gauge R&R process.
This video is focused on the basics terms and concepts within gauge R&R like repeatability and reproducibility and how we combine those two factors to calculate the overall gauge R&R for our measurement system.
Here's Part 2 in the video series: • How to Perform a Gauge...
2:35 - What Is Measurement System Analysis (Gauge R&R)
5:55 - Gauge R&R as a DOE
8:50 - Accuracy Versus Precision
10:10 - Repeatability
12:39 - Reproducibility
14:50 - The Gauge R&R Calculation
17:45 - Next Steps!

[@conorbroderick6394]

Awesome vid! when are parts 2 and 3 coming?

[@greenbeltacademy]

Hey Conor!! I think part 2 will come out here in 3-4 weeks!

[@angiedavenport9291]

Hi Andy, great info! When will the next 2 videos be released?

[@greenbeltacademy]

Thanks! I'm filming that second video this week, and it should be up here in the next few weeks!

[@user-cy1em1od6g]

Thanks a lot for great video! Please advise how the Excel file can be downloaded? Thanks

[@greenbeltacademy]

You're absolutely well!

[@RajeshGupta-gx3yz]

Hi Andy,
Comparing these terminologies with your ANOVA video, can we say that reproducibility/operator variance is treatment variance whereas part variance is error variance in ANOVA and as such repeatability/equipment variance explained in this video was not covered in the ANOVA video, right?

[@greenbeltacademy]

Hey Rajesh!! Yes that is correct!!! Great job making the connection between Repeatability and the MSE (error variance).
In fact, if you use ANOVA to evaluate the results of your gauge R&R, the repeatability term is equal to the MSE (Mean Square of the Error).

[@RajeshGupta-gx3yz]

Thanks Andy, loved your videos :)

[@tariq.hassan]

Hi, does anyone know if gage R&R should be performed without informing technicians about it? Point is if technicians are aware of the study they would do it perfectly and gage R&R study might fail.

[@CQEAcademy]

Hey Tariq, so a blind study (one in which the operators are unaware of the situation, etc) can be helpful if you're worried about possible bias. I wouldn't say it is a requirement though.

[@abunailah3478]

Hi,very good video.
I have question, ia it possible if me as person who will do study also involve as one of appraiser too ?
Is because I know the rule so I can make the result of measuring always precision.

[@greenbeltacademy]

No, I would not recommend including yourself in the gauge R&R study. You should pick appraisers who have the same level of skill and training as the people that you expect to use the tool in production.
If you include yourself, and you have better precision than most people, then you will be artificially skewing your results, and your reproducibility will not reflect the true long-term variation of that measurement system.

[@abunailah3478]

@@greenbeltacademy noted. Thank you

[@deanopenn]

Do you use all the dimensions listed on a drawing or just the SC's on the drawing?

[@greenbeltacademy]

If you don't plan on routinely measuring certain dimensions (Non-critical) during routine production, then a gauge R&R isn't necessary.
But for the dimensions that end up on your control plan - where you are going to make routine measurements - you should consider a gauge R&R.
You could also work with your friends in Quality to determine the worst case dimension for a gauge R&R, which perhaps would the dimension with the tightest tolerance or the smallest process variation.
