This unit investigates into Standardization in the field of Metrology from both the theoretical point of view, the one around units and international organizations and standards who govern the field itself, as well as from the practical one, with focus on the measurement system and the uncertainty and “translation” problems to overcome, such as working on different coordinate systems or even software based on different languages.
This Element includes skills regarding the basic Standards in use in Dimensional Metrology, from the international organizations who manage the International Metric System to Certification Agents such as AENOR in Spain. Based on this, a more deep approach into metrology is performed, defining types of metrology and making an introduction to measurement software (parameters to take into account, coordinate reference system, and standard languages like DMIS and I++/DME, the latter for automotive industry). Some other characteristics of CMMs (Coordinate Measuring Machines) are explained, for example, dimensions and architectures. All these topics are linked with Uncertainty and traceability of the measurement.
