Surface finish samples
WebSurface roughness, often shortened to roughness, is a component of surface finish (surface texture). It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface metrology, roughness is ... Web(1) Geometrical non-uniformity and surface finish of the calibration ball master used to calibrate the instrument. This leads to variations in measurements of the master ball to obtain the calibration constants of the stylus instrument and hence, to an uncertainty in the calibration constants.
