In reply to Shuang L. That's correct! For lower Ra measurements CMM machines are the best choices.

From my experience, stylus probe measurements could not be feasible for lower Ra values like lower than 4 micrometer.

In reply to Freja Andersen. Roughness Grade Numbers and the Ra value are critical parameters in quantifying the surface finish quality of a part. The Roughness Grade Number classifies the roughness of a surface into categories, providing a quick reference for manufacturing standards, while the Ra value offers a precise measurement of the average surface deviations, guiding the machining process for achieving the desired smoothness. Together, they ensure that the surface quality meets both functional and aesthetic specifications required for the part’s intended application.

I learned what i was looking for . But did not understand how Roughness Grade Numbers and Ra Value are important for obtaining desired surface-finish quality.
