Resumo: The machining process is the method more efficient and effective in creation fine parts in which there are many details in need quality and precision. However, there is a strong influence of the temperature in process, due the heat dissipation in the region of contact between the part and the tool. Currently, it is desired to achieve the highest productivity with the lowest expenditure, in the context of this work, the purpose is to increase the life of the cutting tool, and with the application of coating in the cutting region of the tool, it will be possible achieve these improvements that would provide less wear of the tool, achieving higher cutting speeds without increasing the temperature, preserving the integrity of the tool, which would eliminate financial expenses with constant changes of inserts and tools, reducing costs to the company and increasing its productivity. Thus, the research project studies about the termical influence in the coating on the cutting tool, using numerical simulation in a commercial software COMSOL Multiphysics® version 5.3a. It as also estimated the heat flux using the inverse technique of the melhod in the specified function, written using the MATLAB® package, which it was used for obtain the heat variable flux, used for obtain the numeric temperature for a cutting tool coasting in the Titanium Nitride (TiN) with thickness of 20 microns, and later compared wich the uncoated tool.

Sin embargo, existe una fuerte influencia de la temperatura en el proceso, esto se debe a la disipación de calor en la región de contacto entre la pieza y la herramienta. Hoy en día, se desea lograr la mayor productividad con el menor gasto posible. En el contexto de este trabajo, el objetivo es aumentar la vida útil de la herramienta de corte, y al aplicar el recubrimiento en la región de corte de la herramienta, será posible lograr las mejoras que resultarían en un menor desgaste de la herramienta, alcanzando velocidades de corte más altas sin aumentar la temperatura, preservando la integridad de la herramienta, lo que impediría el gasto financiero con los cambios constantes de los insertos y herramientas, reduciendo los costos comerciales y aumentando la productividad. Por lo tanto, este proyecto de investigación estudia la influencia térmica del recubrimiento en la herramienta de corte, utilizando simulaciones numéricas en el software comercial COMSOL Multiphysics® versión 5.3a. El flujo de calor también se estimó usando la técnica inversa del método de función especificado, escrito en el paquete MATLAB®, que usamos para estimar el flujo de calor variable utilizado para obtener las temperaturas numéricas para la herramienta de corte recubierta de Nitruro de Titanio (TiN) con un grosor de 20 micras, y luego comparado con la herramienta sin recubrimiento.O processo de usinagem é um dos métodos mais eficientes e eficazes para criação de peças finas em que se deseja obter muitos detalhes, com qualidade e precisão. Contudo, há uma forte influência da temperatura no processo, isso ocorre, devido a dissipação do calor na região de contato entre a peça e a ferramenta. Nos dias atuais, deseja-se alcançar a maior produtividade com o menor gasto possível, no contexto deste trabalho, o intuito é aumentar a vida da ferramenta de corte, e com a aplicação de revestimento na região de corte da ferramenta, será possível alcançar essas melhorias que proporcionariam menor desgaste da ferramenta, alcançando maiores velocidades de corte sem um aumento da temperatura, preservando a integridade da ferramenta, que dispensariam gastos financeiros com trocas constantes de insertos e ferramentas, reduzindo custos a empresa e aumentando sua produtividade. Dessa forma, esse projeto de pesquisa estuda sobre a influência térmica do revestimento sobre a ferramenta de corte, utilizando simulações numéricas no software comercial COMSOL Multiphysics® versão 5.3a. Também foi estimado o fluxo de calor utilizando a técnica inversa do método da função especificada, escrita usando o pacote MATLAB®, ao qual utilizamos para estimar o fluxo de calor variável, usado para obter as temperaturas numéricas para a ferramenta de corte revestida de Nitreto de Titânio (TiN) com espessura de 20 mícrons, e posteriormente comparadas com a ferramenta sem revestimento.Research, Society and Development2020-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/157210.33448/rsd-v9i1.1572Research, Society and Development; Vol. 9 No. 1; e46911572Research, Society and Development; Vol. 9 Núm. 1; e46911572Research, Society and Development; v. 9 n. 1; e469115722525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/1572/1431Copyright (c) 2019 Rodrigo Dias Nunes Coelhoinfo:eu-repo/semantics/openAccessNunes Coelho, Rodrigo DiasBrito, Rogério FernandesSilva, Sandro Metrevelle Marcondes de Lima e2020-08-19T03:04:08Zoai:ojs.pkp.sfu.ca:article/1572Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:26:32.727147Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
