Surface finish units of measure
WebSurface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. [1] It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane ). WebApr 14, 2024 · The term “surface finish” usually refers to the level of polishing or texturing applied to the surface of a part or component. One of the surface texture parameters is surface roughness. These parameters quantify surface finishing features to regulate the manufacturing process or forecast a component’s behavior during use.
