Reducing electrode wear ratio using cryogenic cooling during electrical discharge machining (2009, background): “The low wear of copper electrode and improved surface roughness of titanium during EDM with liquid nitrogen is as a result of the fact that electrical and thermal conductivities of the electrode and titanium are highly dependent on temperature [ 9 , 19].”
INVESTIGATING THE EFFECTS OF EDM PARAMETERS ON SURFACE INTEGRITY, MRR AND TWR IN MACHINING OF Ti–6Al–4V (2012, background): “( 2008 ) performed temperature measurements for Ti-6Al-4V workpieces with various duty factors to clarify the essential causes of difficulty in machining titanium alloys and observe the optimal duty factor in terms of productivity and quality.”
Turbomachinery component manufacture by application of electrochemical, electro-physical and photonic processes (2014, unknown): “The reluctance in adopting wider utilisation of WEDM has partly stemmed from slower material removal rates (compared to traditional cutting processes), but more crucially the prevailing perception of poor workpiece surface integrity due to the thermal nature of the process.”
Optimization of the EDM parameters on machining Ti–6Al–4V with multiple quality characteristics (2010, background): “Recently, Fonda et al. used EDM technology to machine Ti–6Al–4V alloy to examine the effect of thermal and electrical properties on the productivity [ 4 ].”
