Abstract: This work deals with the micro-Electrical Discharge Machining (EDM) of a commercial TiB2 ceramics grade. The influence of the process parameters on the relative tool wear, material removal rate and surface quality is investigated leading to optimised micromachining performance characterized as follows: 0.19mm3/min and 0.26 m (surface roughness) at high and low discharge conditions, respectively; the relative tool wear ranges within ~15-30%. Furthermore, the morphology and composition of the EDM samples are examined revealing a change in the material removal mechanism, including chemical reaction, melting and spalling, depending on the discharge conditions. Tests are conducted on a micro-EDM milling machine in de-ionized water with brass tool electrodes.
