Experimental investigation of surface integrity after wire electro-discharge machining of Ti–6Al–4V
This article presents the relationship of machining parameters containing pulse-on time (Ton), pulse-off time (Toff), peak current (IP) and servo voltage (SV) on surface integrity characteristics, including white layer thickness (WLT), heat-affected zone (HAZ) and surface crack density (SCD) and als...
