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.
 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.


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.


 these are the form of irregularities on the surface called flaws.
