DETERMINATION OF SURFACE ROUGHNESS MEASUREMENT UNCERTAINTY IN ADDITIVELY MANUFACTURED COMPONENTS

Áron Lóránd, Ágota Drégelyi-Kiss

Abstract


Additive manufacturing (AM) is increasingly used due to its design flexibility and material efficiency. However, the layered structure of AM parts often leads to higher surface roughness and irregular topographies compared to traditionally machined components. Surface texture critically affects performance aspects such as friction, wear, and fatigue. This research investigates tactile surface roughness measurements in AM, focusing on the uncertainties introduced by factors like environmental conditions, human influence, probe interaction, and surface geometry, to which tactile measurement is sensitive. Identifying and quantifying these uncertainties is essential for reliable quality control, accredited testing, and regulatory compliance. A clear understanding enables process optimization and improves functional reliability of AM products.
