Why MSA reproducibility is a blank page

Reproducibility is a blank page, does it mean that the value of reproducibility is zero? If yes, see the answers below.

The MSA focuses on two indicators, "repetitiveness" and"Reproducibility refers to the fluctuations caused by different operators using the same gage and taking multiple measurements of the same part (in Mr. Marin's "Six Sigma Management" (2nd Edition) p176).

This concept is not wrong, but a bit one-sided to draw everyone's attention to the "person", msa Chinese translation is: measurement system analysis, that means that "reproducibility" actually covers all factors except for the inherent fluctuations of the gauge itself (that is, repeatability), "people" is only one of these many factors, depending on the research object, may also include the season, altitude, day or night and many other factors on the impact of the measurement results.

Okay, now say "the reproducibility value is zero", this situation exists, for example, if the operator presses the button every time the CNC machine is placed in an air-conditioned room, imagine whether there is really a difference between your button and my button?!!

Therefore, at this time, the result of MSA is only a reflection of the inherent fluctuation of the gauge itself, which may be caused by the fluctuation of the current in the precision instrument, whether the weight is slightly disturbed by the geomagnetic field, and other factors that are not easy to detect on the surface.

There's a problem with your software or Excel.

Excuse me, whether your measurement system is automatic or not, it has nothing to do with personnel, if this is the case, it is normal, that is, there is no reproducibility problem with your measurement system. Hope it helps.

Reproducibility is the difference between raters.

Sometimes it's just a few tenths of a point, and you can see if the number of numbers is not enough.

Or paste the data up for everyone to analyze.

You calculate the mean of each operator's measurements, and if it's very close, the reproducibility is 0

1.Probably you're not a person surveyor.

2.Maybe your gage doesn't have enough resolution.

Arrange three surveyors, prepare 10 samples, and ask them to measure each part three times at random and record the results.

Please refer to the MSA Handbook 4th Edition for details.

I sent you one to your mailbox, and I don't know if it can answer your question.

The 130kg scale you are looking for in ** is generally 150kg. You may not have figured out what GRR is really studying. Since you are measuring 6kg of the item, he has a allowable error, which is the tolerance you said, you just look for the 10pcs product that the product is evenly distributed within the tolerance.

As far as I know, the repeatability and reproducibility of electronic scales are very good, and MSA analysis is generally done, and stability or offset can be considered.

I have ** here, too. Just fill in the data.

How many email addresses do you have? I'll send it to you.

Don't be too attached to this landlord, since we know that it is a fixed coefficient, we just use it, and we don't have to investigate why this is the case, just like learning English grammar, just follow the calculation.

You can look it up from the table, hand source.

It should be bai

Yes, du or zhi take a look at dao this.

MSA repeatability and reproducibility analysis is commonly referred to as GR&R

How does the visual inspection work? The risk analysis method in the MSA, i.e. the analysis of the counting measurement system, can be used.

How to analyze these values. See MSA Handbook, Fourth Edition.

Appearance inspection is performed for attribute consistency analysis.
