Acesso em:.https://bdm.ufpa.br/jspui/handle/prefix/7914This work aims to develop a thermal management system for welding processes in a CNC, employing a low-cost pyrometer sensor to monitor the temperature between layers. The research involves building an experimental setup that simulates the Z-axis of a CNC, allowing for variation in the distance between the pyrometer and the heat source, as well as data collection for calibration of the proposed mathematical model. The project includes the development of data acquisition software for monitoring and controlling the experiment, alongside a linear regression model to correct the temperature measured by the pyrometer based on readings from a thermocouple. Although the final validation was not possible due to operational issues with the CNC, the results indicate that the proposed correction method is feasible, offering a low-cost solution for thermal monitoring. The bench, software, and model developed in this study can be applied in future research and industrial projects.Acesso AbertoBaixo custoGerenciamento térmicoInterfaceModelo de regressãoPirômetroLow costPyrometerRegression modelThermal managementCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::ELETRONICA INDUSTRIAL, SISTEMAS E CONTROLES ELETRONICOS::AUTOMACAO ELETRONICA DE PROCESSOS ELETRICOS E INDUSTRIAISCNPQ::ENGENHARIAS::ENGENHARIA MECANICA::PROCESSOS DE FABRICACAO::CONTROLE NUMERICOTrabalho de Curso - Graduação - Monografia
