PT Journal AU Palova, K Kelemenova, T TI Specific Aspects of Roughness Measurement SO Acta Mechanica Slovaca PY 2024 BP 36 EP 40 VL 28 IS 3 DI 10.21496/ams.2024.028 DE control system; sensor; traffic light; human machine interface. AB The article deals with problems in determining the surface roughness of parts. The arithmetic mean height of the roughness Ra is mainly monitored. This quantity is most often used when defining the required surface quality of components. Assessment of surface roughness is important in the production of parts, their assembly and their use. This article solves some problems in the process of determining this quantity. ER
