This project aims to discover new theories to overcome the core challenge in electrical discharge machining of polycrystalline diamond. Diamond materials provide the ultimate performance in cutting difficult-to-machine materials such as titanium alloys which are widely used in the aerospace and biomedical industries. However, the extremely slow erosion speed of electrical discharge machining severely impedes their applications. The project will use high energy electrical arcs for the fast machining of polycrystalline diamond. The expected outcome is a new approach and breakthroughs in fundamental knowledge that pave the way for developing new electrical machining methods and lead to significant reductions in manufacturing costs.
