Topographical Condition of Mild Steel after an Orthogonal Cutting

Now a days it is very common interest for engineers to improve the surface quality. Improvement of surface quality deals with several factors like cutting condition, heat generation, heat dissipation, selection of cutting fluid etc. Above all the factors it is very important to know about the change in microstructure and behavior of the material. The surface quality that is the change in microstructure greatly depends on the cutting condition and process which are taken on account earlier, each of which produce a surface with own characteristic topography. In this paper the topographical condition of a mild steel workpiece and chip is investigated and described. For this purpose an orthogonal cutting of mild steel metal with cutting tool of high speed metal is taken. The change in microstructure of chip and work material is observed in the metallurgical microscope. Then finally it is observed, the total change of microstructure of each surface held with the proportion of heat generation and distribution.
