Validating Measurement System Using Measurement System Analysis (MSA)

Third Dimension
25 November 2008

How can you determine whether or not your existing measurement system is 'good enough' for your application? For that matter, how can you establish how much better the GapGun will be?

Most engineers working in automotive and aerospace now know that six-sigma techniques and gauge repeatability and reproducibility (R&R) tests should be used to make such decisions, but do not necessarily have any practical experience of applying them.

Fortunately, Hemant Urdhwareshe, Director of the Institute of Quality and Reliability in Pune, India, has written an excellent short article which provides a great overview of the subject.

The download provides you with a short document which explains in simple terms:

• Repeatability and reproducibility (R&R) .
• Measurement System Analysis (MSA), together with a brief summary of the criteria defined by the MSA Manual published by Automotive Industry Action Group (AIAG).
• Distinct categories, bias, stability, and linearity.
• Interpretation of a simple example using Minitab.

The range of GapGun sensor heads supplied with the GapGun system are designed to meet MSA requirements for automotive and aerospace applications, with typical tolerances raning from +/-0.5mm for a typical automotive gap and flush measurement application, to +/-0.010mm (+/-0.0005") for chamfer, radius and edge control applications. For more information see our range of GapGun sensors.
