Electrolytic plasma polishing technique for improved surface finish of ED machined components

The development of techniques that allow producing high-finish surfaces of geometrically-complex parts of difficult-to-machine materials by electrical discharge machining (EDM) is an emerging research area. The aim of this work is to study the application of electrolytic-plasma polishing technique for the high-quality surface finish of the parts obtained by EDM process. | Electrolytic plasma polishing technique for improved surface finish of ED machined components Engineering Solid Mechanics 7 2019 131-136 Contents lists available at GrowingScience Engineering Solid Mechanics homepage www.GrowingScience.com esm Electrolytic plasma polishing technique for improved surface finish of ED machined components T.

The aim of this work is to study the application of electrolytic-plasma Available online polishing technique for the high-quality surface finish of the parts obtained by EDM process. The 1 April 2019 Keywords structural alloy steel 38KH2N2MA GOST 4543 71 was selected as the processing material. Electrical discharge machining The morphology of the machined surface was examined using optical micrographs. It was observed EDM that applying the electrolytic plasma polishing for the duration of 5 minutes results in reducing the Electrolytic plasma polishing surface roughness of the ED machined surface by a factor of 5. It is also concluded that the Roughness combined action of EDM with electrolytic plasma polishing method is suitable for attaining the Quality desired surface finish. 2019 Growing Science Ltd.
