Resumo: | The electrical discharge machining is an exceptional procedure for machining complex shapes into electric conductor materials, mainly for those of high hardness, difficult of machining by traditional processes. At each discharge, a crater is formed in the material and a small crater is formed in the electrode. From every molten material produced in each discharge, only 15%, or less is removed through the dielectric liquid. The remaining of molten material solidifies forming a wrinkled surface. The characteristics of the obtained surface, as overlap of craters, globules of sullage, “chimneys", bubbles (formed when trapped gases are released through the resolidified material), are revealed through an analysis by scanning electron microscopy. The proposed study aimed to examine the effect of several dielectric fluids, on the surface topography and material removal rate, in workpiece of high speed steel (ABNT M2), during the electrical discharge machining. |

Em cada descarga, uma cratera é formada no material e uma pequena cratera é formada no eletrodo. De todo material fundido produzido em cada descarga, só 15%, ou menos, são removidos através do fluido dielétrico. O restante do material fundido solidifica-se formando uma superfície rugosa. As características da superfície obtida, sobreposição de crateras, glóbulos de impurezas, “chaminés”, bolhas (formadas quando os gases presos são liberados através do material resolidificado), são reveladas através de uma análise por microscopia eletrônica de varredura. O trabalho proposto tem por objetivo estudar o efeito de vários fluidos dielétricos, sobre topografia da superfície e taxa de remoção de material (TRM), no aço rápido ABNT M2, durante a usinagem por descargas elétricas.Universidade Estadual De Maringá2011-02-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAnálise experimentalapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/676310.4025/actascitechnol.v33i1.6763Acta Scientiarum.
