Estudo da usinabilidade dos aços inoxidáveis a partir da variação dos parâmetros de corte: uma avaliação com base no teste de propriedade física

Abstract

Understanding of machining for manufacturing process involves the study concerning both the material of the part to be machined on the tool as well as on the type of machine tool as well as the operation and process variables involved in the cutting of metals that is, an operation that depends on the harmony of all parameters. In this context, the aim of this study is to present a theoretical framework on the machinability of stainless steel from the cutting parameters: an evaluation based on the test of physical properties. Analyzing stainless steels Martensitic, austenitic and ferritic as its authorizations and individual characteristics as well as cutting parameters that affect machinability index from an analysis of their physical propriedads, review the types of machinability tests and the main problems arising of poor machinability. Methodology The work was given from the study proposed Henkin in two parts, the first from Henkin study with data collection in the available literature and later with the builds. All assays were performed in the data processing from the manager needs several repetitions of calculations, and an organization and optimization of the worksheet, to facilitate data entry and obtaining the results and graphs. Thus it was possible to obtain the machinability index expressed in values of the material machining speed
