Estudo na usinabilidade do aço comum ao carbono e aços liga

Abstract

The machinability is related to the ease or difficulty in machining a material, however the term machinability goes beyond this concept, because it is a factor that measures the performance of related factors machining, as a tool of life, their geometries, cutting fluids employed, among others. In the machining industry, steel holds 50% of production costs in the manufacturing of mechanical components, so the need arises to study make the machining of this material easier and to reduce the costs associated with its manufacture. The objective of this work is to study the machinability of carbon steels and alloy steels based on the parameters of machining processes such as: cutting force, cutting temperature, wear of cutting tools, cutting fluids used and surface finish piece and chip formation. Moreover, metallurgical factors will be examined (chemical composition, microstructure, heat treatment, etc.) which cause effects on machinability of steels. The chemical elements that make up the steel, as well as the methods and techniques that make this material easier to be machined, are other aspects to be studied and how it can contribute to achieving improvements in machinability
