| Keyword | |||
| Abstract | This paper mainly discusses the effect of adding dispersant in the machining fluid on the EDM of chromium-molybdenum steel, and the surface roughness of the chromium-molybdenum steel after EDM is the research topic. During the experiment, silicon carbide powder was added to the machining fluid, different concentrations of surfactants were used, and different experimental parameter settings were used to conduct EDM on the metal surface of chrome-molybdenum steel, and the Taguchi test method was used to investigate the change of surface roughness after EDM , processing time and surface morphology observation. In the experiment, a particle size of 4 £gm, a weight concentration of 5%wt. silicon carbide powder, and a span20 surfactant with a weight concentration of 3 wt.%, 6wt.%, and 9wt.% Change the pulse time, high voltage, low voltage, gap voltage and jump in the process of electric discharge machining, and the effect of chrome molybdenum steel surface processing under different parameters. In this study, the discharge parameters were studied and discussed. It was found that the addition of Span20 surfactant to the machining fluid could speed up the machining rate by about 30%, and the surface roughness would not deteriorate from 5.13 £gm to 4.95 £gm. Keywords:chrome molybdenum steel, electrical discharge machining, surface roughness, silicon carbide, surfactant |
