The importance of calibration, verification and actual values

Wednesday, September 2, 2020

Why are calibration, verification and actual values so important for the overall manufacture of a product?
Because they are critical components of the measurement process. 

But there’s more to it than that. Calibration and verification help ensure that readings are consistent with measurements. They minimise measurement uncertainty by ensuring the reliability and accuracy of measurement systems and metrology tools and the data that they generate. The reliability and accuracy of these systems and their data have a direct impact on product quality.
The failure to properly calibrate metrology tools and verify tool data, and receive actual values, can have an adverse effect on product reliability and quality. 

Why tool re-calibration and data verification is critical

The accuracy of metrology tools decrease over time. Repeated use, and the wear and tear that this causes, affects precision. In addition, the environment in which metrology tools are used can have a negative impact on accuracy, whether as a result of shocks or hazards.
This is why it is important to regularly check measurement systems and recalibrate tools, and implement thorough tool data verification processes. This attention to detail and commitment is critical to ensuring tool reliability, the standard of the measurement process and, ultimately, the quality of the end product.
The risks linked to using uncalibrated measurement tools and inaccurate tool data are significant. The costs can be considerable because development processes and quality standards can be negatively affected. Indeed, the price can be more than the cost of maintaining proper calibration and verification systems.

How often to carry out tool calibration and verification checks

How often you need to carry out metrology tool calibration and tool data verification checks depends on the frequency of tool use and the environment in which your measurement systems are operated.
Your checking schedule could be monthly, quarterly or annually. Furthermore, in the event of a mechanical or electrical shock, you should immediately perform tool calibration and data verification tests. And regardless of when you do the checks, they should always be done in accordance with tool manufacturer specifications and by a certified service provider.

Calibration and verification and your metrology partner

Metrology tool calibration and tool data verification are essential tasks and the role of a metrology solutions partner is to help you achieve them to the standard required and according to the appropriate schedule.
The right metrology solutions partner should not only supply you with high-quality measurement sensors and gauging probes, but also, should you need it, with guidance and assistance with tool calibration and measurement verification to ensure your metrology solutions are always functioning to the highest standards and providing the level of performance you need to deliver optimum product reliability and quality.
Calibration, verification and actual values are not high-profile parts of the manufacturing process but they are nevertheless critical ones. It is vital that you have the relevant checks and systems in place. Your metrology partner should make sure that you do.
