Different elements of a surface texture
Surface is the area where this portion of work area is divided by a boundary line when the work done by other surface area.
Normal surface:
it is the theoretical, imaginary perfect surface obtained by calculating the mean of peak and valleys on the surface.
Actual surface:
the surface generated by the manufacturing process is called as actual surface.
Profile:
it is defined as the shape of the surface.
Primary Texture:
it indicates very fine irregularities on the surface.
Roughness Height:
it is the mean deviation of real surface along normal direction from the imaginary surface.
Roughness width:
the distance between adjacent peaks to normal surface is called roughness width.
Waviness:
the irragularities on the surface whose space length is more than roughness is termed as waviness.
Effective profile:
the real surface generated by the instrument is refered as effective profile.
Flaws:
these are the form of irregularities on the surface called flaws.
