| Abstract | In order to solve the problems of poor dimensional accuracy, high-specific energy consumption (SEC), and poor surface integrity in DC short electric arc machining (SEAM), this paper proposes to use W-Ag alloy as the electrode material for machining nickel-based alloy (Inconel 718). Firstly, the effect of voltage and electrode material (graphite and W-Ag alloy) on the material removal rate (MRR), relative electrode wear rate (REWR), surface roughness (Sa), and SEC were investigated, and current and voltage during machining were measured by a multichannel data acquisition system. In addition, the surface morphology, cross section, and element distribution after machining were analyzed. The experimental results showed that W-Ag alloy as a tool electrode can obtain better performance in SEAM; its MRR reach 6314 mm(3)/min at 30 V which is twice as high as graphite electrode. The SEC of W-Ag alloy electrode is 32.64 kJ/cm(3), significantly lower than that of graphite electrode with 84.16 kJ/cm(3). The surface roughness is lower after machining with W-Ag alloy electrode, and the thermal damage layer is only half of that machined with graphite electrode. |
