TAGUCHI OPTIMIZATION OF MULTIPLE PERFORMANCE CHARACTERISTICS IN THE ELECTRICAL DISCHARGE MACHINING OF THE TIGR2

Electrical discharge machining (EDM) provides many advantages for the shaping of metallic materials. It also better surface quality Ti alloys used in defense industry. In this study, experiments were carried out with different EDM parameters using Titanium (Gr2) alloy. A number novel industrial processes have been developed as a result advances technology. For product to be developed, these approaches must utilized determine optimum parameters. The Taguchi method was applied EDM. impact test had on performance characteristics tool wear rate, material removal depth, and roughness analyzed by variance analysis (ANOVA). Quadratic regression analyses reveal correlation between experimental results predicted values. According ANOVA rate (MRR), (TWR), roughness, most effective factor amperage, at 99.66%, 99.56%, 87.95%, 81.12%, respectively. best value average determined 3.29 µm obtained 120 ?s time-on, 8 A, 40 time-off.
