2015 SOLIDWORKS Help - Surface Finish Symbols

Surface finish, also known as surface texture or surface topography, is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. It comprises the small, local deviations of a surface from the perfectly flat ideal (a true plane).. Surface texture is one of the important factors that control friction and transfer layer formation during sliding.
