SUAREZ PAIPA, Mauro; MONTANDON, Renato Lima  e  RASLAN, Alberto Arnaldo. Uso de fluidos dieléctricos a base de aceites en maquinado por descargas eléctricas por penetración. rev.ing. [online]. 2012, n.36, pp.38-42. ISSN 0121-4993.

EDM process commoly use petroleum based died fuids. The aim of this work is to evaluate alternative fuids to traditional mineral ones. It was analyzed 5 different dielectric fuids derived of seeds. They were compared with kerosene and a mineral oil. The workpiece was speed-steel M2. The machining parameters were preestablished for working with copper and graphite electrodes. The material removal rate, the wear rate of the electrodes, the finishing and morphology of machined surface were all measured. Vegetable based oils showed a competitive performance using cooper and graphite electrodes when compared with mineral based oils.

Palavras-chave : EDM; Vegetable oils; dielectric oils; removed rate of material; surface finishing.
