Abstract

There has been a recent increase in the use of diamond tools with the increase in the use of high hardness materials. In this study, the machinability of high hardness ceramic materials was evaluated using an electro-deposited diamond drill. Specifically, the machinability of four types of drills was analyzed by changing the drill shape and electro-deposition method of the diamond particles to address the limitations of commonly used diamond drills. In addition to varying the cutting speed and feed rate, the cutting torque, diamond particle fall-out rate, and roughness of the machined surfaces were compared and analyzed. The results of this study will be helpful in tool design and setting the appropriate machining conditions to improve the machinability of high hardness ceramics using electrodeposited diamond tools.
