Karheusarvot
Karheusarvot is a Finnish term used to describe numerical measures of surface roughness or coconess, expressing the texture of a surface or material interface. The concept is used to compare surfaces, specify quality criteria, and guide manufacturing and finishing processes. In practice karheusarvot appear in fields such as material science, mechanical engineering, textile science, and wood processing.
Measurement and interpretation of karheusarvot rely on profilometry or other surface characterization methods. Commonly reported parameters
Applications of karheusarvot cover quality control, wear and friction prediction, coating performance, and tactile or aesthetic
Limitations and standardization: surface roughness is scale- and method-dependent, and karheusarvot do not represent a single
