TīmeklisSurface finish (Also called sometimes surface roughness) is a numeric representation of a surface’s “smoothness”. There are 3 main ways to acquire the surface roughness value: Mechanical Scan: The most common method is to scan the surface with a needle that records the micro “Hills ” and “valleys” along a linear section.

TīmeklisSurface roughness Ra is rated as the arithmetic average deviation of the surface valleys and peaks expressed in micro inches or micro meters. ISO standard use the term CLA (Center Line Average). Both are interpreted identical. RMS = Root Mean Square in Microinches * (acceptable 1.1 - 1.7 factor) = Multi.
