AVALIAÇÃO DA USINABILIDADE DO AÇO SAE 1020 EM UMA FERRAMENTEIRA COM DIFERENTES FRESAS

Abstract

This essay consists of an evaluation of the machinability in the milling of steel 1020, where it was verified the ideal mill for the process. Such analysis is due to the fact that this type of steel is widely used in the machining in many small size companies of both big and small scales because proper tools are not being used, therefore affecting the revenue of such companies. Such approach is necessary to correct the utilized standards, decreasing the storage of tools, since working according to their lifespan is to be expected, it also aims to decrease workload and to visually better it’s superficial finishing. The objective of this study is presenting a comparative with two quick steel mills, in which one is of national origin while the other is imported and with that demonstrate the best for this kind of steel utilizing a milling machine tool. This task is achieved through bibliographic revision followed by a study case relative to a field research. The result obtained was that steel 1020 possesses good machinability and that mills of foreign origin, despite being made of the same material and possessing the same hardness, is far superior from the national mills.
