Have you ever tried to evaluate the measurement uncertainty after or prior to your coordinate measurement? If you have, you probably realised that it is all but easy. Available standards (ISO 15530 series) give some guidance, but still a lot of educated expertise is needed in most cases. As a result, the measurement uncertainty is very often overlooked at all. But measurements are done for a purpose, and with no measurement uncertainty there is no way to ascertain whether this purpose is achieved or achievable. This is equivalent to buying a vehicle without knowing whether it is a moped, a racing car or a van: would it be adequate for the purpose? In most cases, the uncertainty statement does not need to be accurate and upper bounding is sufficient (PUMA method, ISO 14253‑2).
The EU-funded project EUCoM (Evaluating the Uncertainty in Coordinate Measurement) has the objective of helping industry in this difficult task. Two methods have been developed: an experimental one, where little or no prior knowledge is necessary but some extra measurement is required; and one based on prior information only, which makes prediction of the uncertainty possible.
You are invited to attend the online EUCoM seminar, which summarises the outcomes of the project, and specifically introduces the developed methods.
The seminar is divided in two parts. The first one is in English and gives the background of the project, the outcomes of interest for industry, and a first flavour of its application. The second part is national in national tongue. It reports on the experience gained in the country when applying the methods, and collects questions, impressions and suggestions. See the table below for details.
The seminar is free, but you are required to register.
Why you should join this Seminar?• Learn about the latest developments on implementing simplified ways of determining CMM measurement uncertainty
• Opportunity to give feedback on the methods
• Learn about future standardisation work
• Workshops in both English and your local language
• Network with likeminded professionals across Europe
WHEN: Plenary session: Tuesday 29th June 2021, 9:30‑14:30 (CEST – Central Europe Summer Time) (The plenary and some national sessions are over; see below for the proceedings)
