Comparativo entre ferramentas de materiais de nitreto de boro cúbico e cerâmica à base de alumina: estudo de caso realizado em uma empresa do Polo Industrial de Manaus

Abstract

As technology advances in great strides and constantly points to new market guidelines, companies need to create ways to develop their processes continuously to remain competitive in the segment in which they operate. This requires companies to look for ways to optimize their manufacturing processes in order to increase productivity, product quality and constantly reduce costs to invest in areas that technological advances present to us. Therefore, it is important to analyze how productive flows can improved to become effective. The present work aims to present a comparison between two cutting inserts, the first of cubic boron nitride and the second of alumina-based ceramic in a process of boring the cylinder liner of a motorcycle, the material of the part to be machine is grey cast iron. The purpose is to evaluate the most appropriate tool in terms of productivity, costs and that meets the qualities of the processes as specified, through the monitoring of the service life of the cutting inserts, identifying the properties of the material to be machine, cutting parameter for tool and roughness of the part. From this, it will be possible to determine the most viable insert manufacturing material that meets the specifications of the machining process.
