| Credits/ECTS : |
|
|
| Holder(s) : | Maarten Arnst |
|
| Language : | French language |
|
| Course contents : | Definitions and significance of several concepts (true value, errors, uncertainty...)
Expression and evaluation of uncertainties according to GUM. Type A and B uncertainties. Practical examples of calculation.
Abbe principle. Traditional versus 3D Metrology. Influence parameters of measurement result (temperature, instrument, method, surroundings...).
Conformity checking of a mechanical part to its design specifications.
Mathematical measurement data processing. SPC (Statistical Process Control).
Practical exercises on the use of measurement instruments and their sources of uncertainties. |
|
| Course objective : | Uncertainties of measurement : the aim is to give
- a complete information about the expression of a quality measurement result,
- a reliable method (from GUM: Guide for the expression of Uncertainties in Measurement) for international comparisons of physical measurements, such weight, pressure, time...
Dimensional Metrology : the aim is to give theorical and practical knowledge in order to understand the physical meaning of a geometrical measurement result.
A special attention is turned to the verification of mechanical parts (e.a. respect of tolerancies). |
|
| Prerequisites : | Statistical methods. Geometrical tolerancing.
Technical drawing. |
|
| Workshops : | Exercises about metrological instruments and measuring methods : internal diameter, threading,.... Tridimensional control |
|
| Organization : | from october to december |
