Basics of surface roughness || Surface Finish || Mech Realm

In this video, Deepak Kumar Kanaujia, is telling about :-
1) Surface Topography / Texture / Finish
2) Lay
3)Waviness
4) Surface Roughness
5) Flaw
6) Surface Roughness indication
7) Machining 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.[1] 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. Considerable efforts have been made to study the influence of surface texture on friction and wear during sliding conditions. Surface textures can be isotropic or anisotropic. Sometimes, stick-slip friction phenomena can be observed during sliding, depending on surface texture.
