Proposta metodologica para o estudo da integridade superficial do aço SAE 8640 no torneamento com inserto quadrado de metal duro

Abstract

Material machining is a process widely used in component manufacturing. In the process, the understanding of the variables present determines the final result in terms of speed, resources spent and the final quality of the operation. The study of machining, its parameters and variables involved comes from the need for alternatives that allow greater tool versatility, lower process cost and greater productivity combined with higher quality. The present work gathered a solid bibliographical literature that allowed to propose a practical experimental test that will evaluate the impact of different machining strategies using the square carbide insert on the surface finish of SAE 8640 steel with and without lubrication and cooling.
