What is the difference between roughness and waviness?

WebBandpass waviness allows us to separate surface texture into 3 domains: roughness, waviness and form. A specification of bandpass waviness may look like this: This specification means that short wavelengths (between 0.0025 and 0.8 millimeters) are classified as roughness and are controlled by the average roughness (“Ra”) parameter ... WebThe surface measurement technique is the measurement of the properties (regular models, irregularities, roughness, waviness, critical dimensions, etc.) of a surface.

"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. " - Roughness and waviness difference
