Abstract: Different thickening agents are added into the prepared water-based working fluid for electrical discharge machining (EDM), and the influence on the process performance is investigated in this paper. The experimental results demonstrate that the proper addition of polyvinyl alcohol (PVA) and coconut diethanol amide (CDEA) can increase the material removal rate of EDM, advance the electrical conductivity of the working fluid and enlarge the discharge gap, but has a little influence on the relative electrode wea…
