Importance Of Surface Characteristics In Manufacturing
Surface of the produced parts have a very specific topic in manufacturing. There are bunch of surface characteristics are defined for surfaces. Also some kinds of surface parameters are produced in manufacturing history to define a surface exactly. In this article, we will summarize these surface parameters basically.
To define a surface, there are some kinds of surface texture parameters;
As we stated above, surface roughness is very important parameter that defines the vertical9Lm deviations from nominal and ideal surface structures. And the average roughness can be calculated with a formulation below;
It is basically the surface integration of deviations(y) that lie on the lenght of a workpiece or surface(Lm).
Surface roughness formula calculates the problem like above illustration. ‘Lm’ is the whole length of the surface. You can see the areas that are created with deviations(y) from nominal surface. We calculate this area with a integration and divide this area with ‘Lm2 to find out the average roughness of a surface.
All the surface characteristics are defined above must be illustrated on technical drawing like above. Placements of surface characteristics is very important in terms of technical drawing standards.
Surface phenomenon in manufacturing can be summarized like above. Leave your comments and questions below about ‘Surface Parameters In Manufacturing’!
