Waviness is the measurement of the more widely spaced component of surface texture. It is a broader view of roughness because it is more strictly defined as “the irregularities whose spacing is greater than the roughness sampling length”.
Waviness is the measurement of the more widely spaced component of surface texture. It is a broader view of roughness because it is more strictly defined as “the irregularities whose spacing is greater than the roughness sampling length”. It can occur from machine or work deflections, chatter, residual stress, vibrations, or heat treatment. Waviness should also be distinguished from flatness, both by its shorter spacing and its characteristic of being typically periodic in nature.

TECHNOLOGIES
Optical profilers like ProFilm3D are interference microscopes and are used to measure height variations – such as surface roughness – on surfaces with great precision using the wavelength of light.
APPLICATIONS
Surface measurement, synonymous with surface metrology is able to determine surface topography, which is essential for confirming a surface’s suitability for its function.
