Experimental Investigations into Wire Electrical Discharge Machining Process for the Machining of Ti-6Al-4V
In the present work, an experimental investigation on Ti-6Al-4V is conducted for micro-slit cutting operation using wire electrical discharge machining process. The objective is to analyse the effect of different input parameters such as discharge energy per pulse, wire feed rate and wire speed on the typical responses such as average cutting/machining rate and average kerf loss. Further, the machining rate and kerf loss are also compared by performing the machining operation at different angles of inclination from the horizontal axis. Finally, applying the kerf loss data obtained at a certain set of input parameters (discharge energy and wire feed rate) a multi-slit operation has been performed to fabricate ultra-thin wall. A minimum wall thickness of 8.78 µm between two adjacent slits was accomplished using wire displacement approach.
