Recently, there has been an increase in the demand for the machining of high-hardness materials using diamond electro-deposition tools. However, a systematic analysis of these tools in terms of machinability has not been performed yet. In this study, a tool design optimization is performed to improve the machinability of diamond electro-deposition drills in drilling SiC ceramic materials. Each drill is analyzed using FEM analysis and the results are compared with the corresponding experimental results. Additionally, the particle drop rate and surface roughness of the machined surface are analyzed for each drill. Consequently, we discover that the most important aspect in drilling using a diamond electro-deposition drill is the proper discharge of the machined chip. Furthermore, we determine the optimal drill shape for the improvement of machinability.
