In manufacturing
industry, a material which has more than 60 HRC hardness value; conventional
methods are not effective as much as non-traditional methods. Therefore, it is
required to use alternative methods like electric discharge machining (EDM)
which has a high hardness and complex geometry advantages. In this experiment a
EDM method presented for different electrode grades. Graphite has a better
machining performance for EDM than other electrode materials. EDM effects on material
removal rate (MRR), electrode wear rate (EWR) and peak surface roughness (Rz) experimentally
determined. Selected parameters were graphite type as electrode material (HK3,
HK15, HK 75), current (2, 3, 4), pulse on time (Ton - 25, 30 and 35µs) and pulse
off time (Toff - 15, 20 and 25 µs). Differences in the MRR results in the
change in the Rz higher values of parameters increased Rz, MRR and Rz values.
In this experiment Taguchi L9 orthogonal experimental design method has been
used on WP7V hybrid tool steel.
