Definitions:

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.

Micrometer

A micrometer is a precision measuring instrument that can measure extremely small distances, thicknesses, or diameters, often used in machining and mechanical engineering.

Microinch

A unit of length equal to one millionth of an inch, often used in the precision measurement of surface roughness in engineering.
