Surface finish, Also known as surface texture or surface topography, is the nature of the surface, as defined by three characteristics of lay, surface roughness, and waviness
The surface texture is one of the important factors that control friction.
Each manufacturing process, (such as the many kinds of machining) produces a surface texture.
the surface finishing process is Grinding, Polishing, Lapping, Honing, etc.
Reasons for controlling the surface texture:
Improve the service life of the components.
Improve fatigue resistance.
Reduce frictional wear.
