Abstract
Electrical discharge diamond cut-off grinding (EDDCG), which is an abrasive based hybrid machining process comprising of diamond cut-off grinding (DCG) and electrical discharge machining (EDM) with rotating disk, is gaining popularity in machining of advanced engineering materials such as titanium alloys, super alloys, cemented carbides, cemented nitrides, metal matrix composites, etc. This article reports the experimental study of EDDCG during machining of titanium alloy (Ti-Al-Mo-V) for material removal rate (MRR) and average surface roughness (Ra). The experiments were carried out on a self-developed EDDCG attachment on ZNC EDM. The effects of main machining parameters such as wheel rotation per minute (RPM), current, and pulse on-time have been studied. The effect of the abrasion and electroerosion on the workpiece surface machined by EDDCG has also been observed using scanning electron microscope (SEM) and results are reported. Experimental study shows that Ra decreases with an increase of wheel speed and pulse on-time, but Ra increases with an increase of current. Furthermore, it is also observed that the MRR increases with increase of wheel RPM, current, and pulse on-time.
