| description | In this paper, the effect of the tool’s material and the workpiece rotational speed on the near dry electrical discharge machining (N.D-EDM) has been studied. In order to, three levels of the workpiece rotational speed and the discharge current are used for evaluating material removal rate (MRR), tool wear rate (TWR) and surface roughness (SR). After doing the experimental study and getting the appropriate speed, a comparison has been done between the fixed and rotary workpiece N.D-EDM. Finally, another comparison has been done between the fixed workpiece N.D-EDM with CO2 gas and the submerged EDM. The results show that the rotational speed of 600 rpm cause to increase in material removal rate, tool wear rate and the reduction in surface roughness. In addition to, the comparison between rotary and fixed workpiece N.D-EDM explain that rotary state have the higher rank of efficency. Due to the low level of electrical resistivity of copper tool, it has the highest MRR and by increasing the discharge current, the highest TWR than other tools. Also, the surface roughness of the workpiece in the fixed N.D-EDM is less than submerged EDM. |
