Abstract
Electrochemical discharge machining process (ECDM) can perform drilling operation on conductive or non-conductive materials. However, the accuracy and efficiency of the process is still limited. Different methods were reported to improve the ECDM process. Tool modification is one of the reported methods for ECDM process. Although fabrication of the reported tools is complicated, they also require additional processing. This article reports the competitive study on ECDM process using solid and hollow tool electrodes. The mechanism of material removal using solid and hollow tool electrodes is discussed. The results show that the use of hollow tool electrode enhanced the performance of ECDM process by increasing the numbers of discharges at inner edge. Through holes were drilled using solid and hollow tool electrodes. The use of hollow tool electrode reduced the drilling time by 34.66%. Also, hollow tool resulted in lesser entrance and exit diameter as compared to solid tool electrode.
