Owing to low machining e ciency, poor machining accuracy, and surface quality in traditional electrical discharge machining (EDM) of TC4 titanium alloy holes, an EDM trepanning method was developed using a deionized water medium and a ushing liquid in tube electrodes (denoted by EDM-TFD). Several experiments and research mechanisms were conducted on EDM-TFD. Compared with traditional EDM, ED milling, and EDM trepanning, EDM-TFD featured increased hole machining e ciency by more than 5 times, improved machining taper by more than 57%, and improved surface quality by more than 40%. The optimal processing technology was determined through process experiments using copper tube electrodes, a ushing liquid with a speed of 2 m/s, pulse width (Ton) of 150 μs, pulse interval (Toff) of 150 μs, and peak current (Ip) of 15 A. Under the optimized process, the hole exhibited a feed rate of 1.1 mm/min, machining e ciency of 38 mm3/min, machining taper of 40 μm, and surface roughness of 5.2 μm.

“…Hence, electro discharge machining (EDM), highlighted by the irrelevant machining power and adequate tooling cost, is a potential forward-thinking machining method for both the conductive and intermetallic ceramics.Copper electrodes have greater electrical conductivity and hence EDM process can be accomplished with better metal removal and surface integrity with a reduced electrode wear rate and EDM is considered for this research for machining of conductive and inetermetallic ceramic composite [19].…”
