Precision instruments in dimensional metrology Mitutoyo measuring instruments incorporating these scales provide the . Note: This part has been written by Mitutoyo based on its own interpretation of the JIS Quality Control Handbook. Metrology Handbook - The Science of Measurement This handbook is used as reading material for trainees at the Mitutoyo Institute of Metrology.

Attribute studies test the level of agreement between multiple are useful for measurement systems which give a pass or fail result and not an actual measured value. Measurement uncertainty is a complex technique which can assess all aspects of a measurement system. Practical tests and combined to understand the overall uncertainty in a measurement. Table 1 - Validation Methods Many reference guides exist on carrying out these studies, some of which are listed in the Standards, Training and Further Reading section. However, it is possible to be repeatable and reproducibly wrong! The measurement system could give very stable results over a range of repeats and operators but could be consistently reading small or large. This error is called bias. Calibration will help to minimise bias however an element of bias can come from the application itself. In order to assess bias it is important to get data from an independent measurement system. Table 2 shows the minimum number of repeats which should be used for a given number of parts and operators.

Metrology Handbook This page handbook covers the underlying principles,technology and application of a wide range of measuring equipment from basic tools to some of the most sophisticated inspection equipment available today.

Calibration will help to minimise bias however an element of bias can come from the application itself. In order to assess bias it is important to get data from an independent measurement system. Table 2 shows the minimum number of repeats which should be used for a given number of parts and operators.

Table 2 - Minimum numbers of repeats for operator and part combinations Rolls-Royce plc 10 3. A1: Not unless you are trained to use the gauge and familiar with the component being measured.

It would be far better to compromise on the amount of measurement readings than to perform a study that is not representative of the way the process works. Q2: We cannot get access to 10 parts, will 5 do?

A2: Lowering the sample size will affect the reliability of the test. However there are times when this may be required.

In difficult situations, a compromise may be required but the analyst should be mindful when interpreting the data. Q3: We cant get parts that represent the full process variation as the only ones we have are from the same batch. What should we do? A3: Testing with a small subset of the possible input conditions is possible but will result in lower confidence in the results and any conclusions.

Consider alternative ways of expanding the variation in input condition and consult someone experienced in measurement systems analysis for advice on experimental design, analysis and conclusions.

Q4: We have very low volumes, only a couple of parts are available.

What can we do? A4: In this situation you could measure multiple features on the same part. See A3 regarding input condition variation and advice. A5: No, in most situations this should not be required. Q6: The gauge is automated there is no operator influence! What do I do? A6: First, be sure that there really is not any operator influence - for instance if there is a setup process which is manual then this may lead to reproducibility problems.

If the gauge is completely automated then a study can be performed with only 1 operator. Rolls-Royce has specifically developed an alternative validation method for surface texture machines; this is outlined in MXG which is available on the Measurement Intranet. If this method is not appropriate for your application a specialist should be contacted for guidance.

If the part tolerance is changed it might be necessary to repeat a gauge study as the change in tolerance can impact on the manufacturing process which in turn can affect the capability of the measurement process.

Is my measurement process good or not?

A9: It is likely that the parts selected for the study are not representative of the total process variation. If the parts are representative then the measurement process is not adequate for the application of SPC analysis as the majority of the variation seen will be from the measurement system and not the underlying process.

Environmental changes in temperature, humidity, vibration etc. New inspectors or operators Regular calibration ensures that the measuring equipment retains its capability and traceability and the periodicity of the calibration should be based upon the usage wear or deterioration. Often calibration intervals are based upon time which can vary from a few weeks to several months. If a gauge was accidentally dropped and damaged without the knowledge of the user then the gauge may give the wrong results.

Consequently it is essential that a regular check of the performance of the measurement system is carried out. There are two straightforward, quick methods for achieving this which should be carried out on a frequent basis, typically daily: Artefact Check A set of known reference artefacts can be checked on a regular basis.

Typical artefacts can be gauge blocks, ring gauges, spheres or length bars. For more complex measurement systems such as CMMs then a combination of these can be used. Figure 4 - Zeiss Artefact Gold-Standard Part Whilst an artefact is very simple and quick to achieve it does not test all elements of a measurement system.

On complex systems such as CMMs or vision measurement machines other elements of the system such as component fixturing, programs and probe angles can have a big impact on performance.

In these cases it is better to have a scrap part which is kept to one side. The part can be measured on a regular basis and the results compared to the original measured results for the part.
