Abstract

Micro-electro-Discharge Machining (Micro-EDM) for shaping of a spherical tool made of Poly Crystalline Diamond (PCD) has been developed for the purpose of enabling a grinding process of a micro-free form surface on hard and brittle materials. Using this spherical PCD tool as a grinding tool, the surface roughness of a minute flat plane (90 x 70 gm), which was ground into tungsten carbide, has 28 nm Rz and 5 nm Ra. This paper describes the capabilities of spherical PCD tool grinding with the following results.
