Surface metrology courses, in video



This page provides a series of educational videos initially made in French (but some are available with English sub-titles), on surface texture analysis methods, instrumentation and other topics.
The Youtube cannel is available on:  Surface metrology courses.




Introduction to surface texture characterization

This video explains why surface texture specifications are important on industrial parts and consumer products, and introduces the basis of surface texture analysis.
Duration: 12 min 50. [English sub-titles available]



Amplitude parameters of ISO 4287

This video introduces amplitude parameters calculated on profiles, as defined in ISO 4287 and ASME B46.1 standards.
Duration: 8 min 16 [English sub-titles available]



Preparation of optical measures

This presentation discusses the preparation and cleaning of surface data measured with a 3D optical profiler, in order to remove outliers and fill-in non-measured points. This operation is mandatory before the metrologic analysis in order to get sound results.
Duration: 10 min 19 [English sub-titles available]
