Abstract
Electrochemical discharge machining (ECDM) is a suitable process for the fabrication of microholes and microchannels in the nonconductive materials such as glass. In the ECDM milling, in some conditions, the tool is penetrated to the workpiece, which may lead to a breakage in the tool. In order to avoid the tool breakage, machining the parameters such as feed rate should be selected appropriately. In this study, the bending force applied on the tool was evaluated as a function of tool diameter, electrolyte concentration, presence of the magnetic field, and tool feed rate. The maximum feed rate, which keeps the bending tool force in the constant ranges, is desirable. According to the experimental results and combination of the machining parameters, the optimum feed rate was obtained. The results showed a decrease in the bending force by increasing the electrolyte concentration and elevating the applied voltage. In addition, the significant effect of a magnetic field on the reduction of bending force in the lower concentration of electrolyte (15 wt%) was observed.
