Resumo: The demand for Nitinol (SMA) is increasing rapidly for various applications. With the aim of optimum control parameters of EDM, 46 experiments completed on six specimens of 6.156 mm thickness using Sparkonix EDM drill machine. Current (I), voltage (V), charging-time (TON), discharging-time (TOFF), and dielectric pressure (DP) were taken as input control parameters. Single-indexed optimization of material removal rate (MRR), tool-wear rate (TWR), and degree of tapperness (DoT) are evaluated using gray relational grade (GRG). Individual control-parameter contributions are evaluated using Taguchi and ANOVA. The obtained optimal input control parameters were used for the confirmation experiment, and the obtained result gives good agreement to it. V and TON are found as the most significant parameters. Maximum and minimum values of MRR, TWR, and DoT have been recorded as 0.0277 & 0.0074 g/min, 0.0177 & 0.0033 g/min, and 0.032 & 0.01 radians respectively. MRR, TWR, and DoT improved by 49.1, 4.5, and 43.3 %, respectively.

Com o objetivo de otimizar os parâmetros de controle de EDM, 46 experimentos foram concluídos em seis corpos de prova de 6,156 mm de espessura usando a máquina de perfuração EDM Sparkonix. Corrente (I), tensão (V), tempo de carga (TON), tempo de descarga (TOFF) e pressão dielétrica (DP) foram tomados como parâmetros de controle de entrada. A otimização de índice único da taxa de remoção de material (MRR), taxa de desgaste da ferramenta (TWR) e grau de rosqueamento (DoT) são avaliados usando o grau relacional cinza (GRG). Contribuições de parâmetros de controle individuais são avaliadas usando Taguchi e ANOVA. Os parâmetros de controle de entrada ótimos obtidos foram usados para o experimento de confirmação, e o resultado obtido dá uma boa concordância com ele. V e TON são encontrados como os parâmetros mais significativos. Os valores máximo e mínimo de MRR, TWR e DoT foram registrados como 0,0277 e 0,0074 g / min, 0,0177 e 0,0033 g / min e 0,032 e 0,01 radianos, respectivamente. MRR, TWR e DoT melhoraram em 49,1, 4,5 e 43,3%, respectivamente.Universidade Federal de Viçosa - UFV2021-08-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1300710.18540/jcecvl7iss4pp13007-01-17eThe Journal of Engineering and Exact Sciences; Vol. 7 No. 4 (2021); 13007-01-17eThe Journal of Engineering and Exact Sciences; Vol. 7 Núm. 4 (2021); 13007-01-17eThe Journal of Engineering and Exact Sciences; v. 7 n. 4 (2021); 13007-01-17e2527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/13007/6823Copyright (c) 2021 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSahoo , Amiya KumarPandey , PraneetMishra, Dhananjay R.2021-12-16T18:51:58Zoai:ojs.periodicos.ufv.br:article/13007Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2021-12-16T18:51:58The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
