Definitions:

Micrometer

A precision measuring instrument capable of taking very fine measurements, often used in mechanical engineering and metalworking to measure thicknesses or diameters.

Predominant Surface

The surface area of an object that is most prevalent or has the largest extent, often having significant functional or aesthetic implications.

Waviness

A form of surface irregularity characterized by wave-like undulations, which is considered when assessing surface texture and quality.

Roughness

Refers to the texture of a surface and is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form.
