produced copper–tungsten tool produced improved performance than the conven-

tional copper tool.

Graphite is becoming common electrode material for die-sinking EDM. It offers

greater advantages compared with copper electrodes. Klocke et al. [34] have inves-

tigated the specic wear behavior and MRR in detail and related the physical char-

acteristics of the graphite material. Sen et al. [35] have conducted EDM of alloy of

Ti–6Al–4V–xB (with x = 0.00, 0.04, and 0.09) with three different proportions of

the alloy as shown using a copper electrode. The analysis has shown that MRR is

unaffected by B addition, and it is also found that with B addition, TWR is consid-

erably reduced ...
