Abstract

As a result of the 2021 standard change affecting surface roughness measurement, we developed a software to calculate the parameters characterizing surface roughness according to the latest, ISO 21920:2021 standard, as the university currently does not have evaluation software or measuring device capable of this. The purpose of this article is to present the new data processing procedure in detail, and to validate the correctness of the procedure with measurements performed on turned artefacts with a Mitutoyo SJ 301 roughness measuring instrument. This was done by comparing the calculated values with the ones ​​shown by the device. As a result, we obtained minor differences, which can be explained by the difference in numerical methods as well as the new procedure.
