Resumo: The use of austempered nodular cast iron (austempered ductile iron – ADI) in engineering projects has gained notoriety due to its mechanical properties such as high strength and hardness combined with high ductility. The rise in the use of this material in the civil construction, mining, automotive, agricultural and railway industries has increased the demand for more elaborate studies regarding the machining of this material. In the front (or top) cooling of the ADI, the thermal and mechanical effects that occur during machining can cause changes in the quality of the machined surfaces and their hardness. This work aims to study the relationship between the cutting parameters used in face milling and the quality of ADI machined surfaces. The milling tests used a carbide tool and the cutting speed, cutting depth and use or not of lubricant-coolant fluid were varied. Subsequently, the roughness parameters Ra and Rz were measured for each condition evaluated. The evaluation of the Vickers hardness of the machined samples complemented the study. Considering all the machining conditions evaluated in this work, all Ra roughness results were below 1.2 ?m and all Rz roughness results were below 5 ?m, presenting an excellent surface finish of the ADI.

A ascensão da utilização deste material nas indústrias de construção civil, mineração, automotiva, agrícola e ferroviária fez crescer a demanda por estudos mais elaborados quanto a usinagem deste material. No fresamento frontal (ou de topo) do ADI, os efeitos térmicos e mecânicos que ocorrem durante a usinagem podem causar alterações da qualidade das superfícies usinadas e na sua dureza. Este trabalho tem por objetivo estudar a relação entre os parâmetros de corte utilizados no fresamento frontal na qualidade das superfícies usinadas do ADI. Os ensaios de fresamento empregaram uma ferramenta de metal-duro e variou-se a velocidade de corte, a profundidade de corte e uso ou não fluido lubri-refrigerante. Posteriormente foram mensurados os parâmetros de rugosidade Ra e Rz para cada condição avaliada. A avaliação da dureza Vickers das amostras usinadas complementaram o estudo. Considerando todas as condições de usinagem avaliadas neste trabalho, todos resultados de rugosidade Ra ficaram abaixo de 1,2 ?m e todos os resultados de rugosidade Rz ficaram abaixo de 5 ?m, indicando um excelente acabamento superficial do ADI.Universidade Federal de Viçosa - UFV2024-01-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1779010.18540/jcecvl10iss1pp17790The Journal of Engineering and Exact Sciences; Vol. 10 No. 1 (2024); 17790The Journal of Engineering and Exact Sciences; Vol. 10 Núm. 1 (2024); 17790The Journal of Engineering and Exact Sciences; v. 10 n. 1 (2024); 177902527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/17790/9166Copyright (c) 2024 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPaula , Pedro Paulo Rosa deBenini, LucasMoraes Junior, José MauroTavares, Sérgio Souto Maior2024-03-26T17:19:32Zoai:ojs.periodicos.ufv.br:article/17790Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2024-03-26T17:19:32The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
