摘要：

The dielectric fluid plays an important role in electrical discharge machining. Kerosene is the most commonly used dielectric, but it is inflammable, easy to decompose and pollutes the air in the processing. Water is nonflammable and has no pollution when it is used as the dielectric in electrical discharge machining, but the material removal rate of machining large surface is low and the machine tool is easily eroded. Emulsion-1, emulsion-2 and emulsion-3 for electrical discharge milling SiC ceramic are developed in this paper. ACE is used as the emulsifier, OP-10 is used as the cleaner, and the rosin is used as the blasting agent. The effects of composition and concentration of additives on the process performance such as material removal rate (MRR) and surface roughness (SR) have been investigated. The results show that with proper concentration of ACE, OP-10 and rosin, the higher MRR and the lower SR can be obtained. The optimal concentrations for ACE, OP-10 and rosin in emulsified oil are 25 wt%, 1 wt% and 2 wt%, respectively. In addition, the workpiece surface machined in emulsion-1, emulsion-2 and emulsion-3 is examined with a scanning electron microscope.
