How do you do GR&R in JMP?

How do you do GR&R in JMP?

Run Variable MSA in JMP:

1. Click: Analyze > Quality & Process > Measurement Systems Analysis.
2. Select “Measurement” as “Y, Response”
3. Select “Operator” as “X, Grouping”
4. Select “Part” as “Sample, Part ID”
5. Select “Gauge R&R” as the “MSA Method”
6. Select “Crossed” as “Model Type”
7. Click “OK”

What is a good GR&R?

A good measurement system has very low noise, preferably less than 1% of the total variability in your data, indicated as a gage R&R of less than 10%. A poor system will have noise greater than 9% of the total variation, or a gage R&R greater than 30%.

What is GRR analysis?

→ GRR Study (Gage R&R) is a methodology used to determine the amount of variation in the measurement data due to the measurement system. → The full name of the GRR is Gauge Repeatability and Reproducibility that is a very important part of Measurement System Analysis.

How do you do GR&R?

A GR&R study can be planned using the following 5 steps:

1. Define the objective of the study.
2. Define the components of the study.
3. Make the measurements.
4. Calculate the %GR&R.
5. Take action to improve the measurement process.

Can you do a gage R&R with one operator?

You can perform a Gage R&R Study with one operator using Gage R&R Study (Crossed) or Gage R&R Study (Expanded). In Gage R&R Study (Crossed), you must also select ANOVA as the Method of Analysis.

What is a nested Gage RR?

The form of gage study used in destructive scenarios is called a Nested Gage R&R study, wherein each appraiser measures a different sample of parts but where the parts of each type are assumed to be very similar (homogenous).

When should MSA be studied?

The rule is very simple: Whenever a measurement is being used to assess the quality or quantity of a product, a measurement system study is required. This means that all measurement systems should be assessed statistically.

Does tolerance affect Gage R&R?

The range or the engineering tolerance does not affect the measurement, but is an important factor in evaluating the viability of the measurement system.

What is MSA and GR&R?

Measurement system analysis (MSA), also known as a gage R&R (GRR) study, is a critical tool in understanding the capabilities of any system used to measure a part or a specimen.

How do I study MSA?

Obtain at least 10 random samples of parts manufactured during a regular production run. Choose three operators that regularly perform the particular inspection. Have each of the operators measure the sample parts and record the data. Repeat the measurement process three times with each operator using the same parts.

What is NDC in Gage R&R?

NDC is the Number of Distinct Categories. It is a measurement of the variation in your sample parts. If your NDC is less than 5, there isn’t enough part variation to use the Average and Range Method or the ANOVA method to calculate Gage R&R.

How do you determine repeatability and reproducibility?

To assess the repeatability and reproducibility, use a gage R&R study (Stat > Quality Tools > Gage Study). Repeatability is the variation due to the measurement device. It is the variation that is observed when the same operator measures the same part many times, using the same gage, under the same conditions.

What types of gr&r studies can I perform in JMP?

The MSA platform in JMP can also perform more traditional GR&R studies (also accessible via the Variability/Attribute Gauge Chart platform). These studies use the established AIAG standards to gauge how much variation your measurement systems contribute to the overall variation.

What is the degradation platform in JMP?

The Degradation platform in JMP lets you analyze product deterioration data over time to help predict product quality and warranty risk. Use the JMP Degradation platform to make performance predictions using data gathered before products or components become ineffective (soft failures) or fail completely (hard failures).

How much does a JMP subscription cost?
