Estudo da usinabilidade com base nos aspectos metalúrgicos dos aços

Abstract

The machining operation represents 50% of the cost of production in mechanical components. The study of its actions with its metallurgical effects as: chemical composition, cold work, microstructure and inclusions have a marked effect on the machinability of this class of metallic materials. The present work has the objective of evaluating a machinability of the steel in front of few metallurgists, through a collection of bibliographical researches. It was possible to verify that there is no cold work to promote the increase of the hardness and decrease of the ductility of steel and to promote its hardening. It was also found that on the matter of the chemical composition and the microstructure it is possible to check, respectively, by means of a phase change, a thermal treatment at a machinability and the increase of the sulfur content, Favoring less wear of the tool flank Cutting. It is possible to verify that the wellbeing of steel, its characteristics and other alloying elements and knowing some of the process processes has improved process
