Optimization of Machining Parameters in Electrical Discharge Machining Process of Ti-6Al-4V Alloy by Taguchi Method

Ishita Gupta, Gauri Tyagi


Electrical discharge machining (EDM) process has been made for creating holes in materials that are tough to machine, by creating sparks between the face of stationary tool electrode and workpiece. This paper depicts the effect of various input process parameters of EDM, such as discharge current, pulse on-time and pulse off-time on the respective outputs: material removal rate (MRR), tool wear rate (TWR) and average surface roughness (ASR). This process has been done on titanium grade 5 alloy.
