Abstract

Electrochemical Machining is a non-traditional machining process that uses electro- chemical reactions to remove materials from the workpiece. In this work , micro hole are produced on the titanium alloys with combination of C3H8O3 and C8O7 electrolytes and the machining parameters such as voltage , Duty Cycle , Feed rate and Electrolyte Concentration with different levels for measuring Material removal rate and overcut.Taguchi-designed L16 orthogonal array was used to conduct the experiments. The results revelated that highest MRR is achieved at a voltage of 14V, electrolyte concentration of 65g/L, feed rate of 0.3mm/min and a duty cycle of 65- 75%. the Higher voltage provides more energy for the electrochemical process, which enhances the electrolytic dissolution of the workpiece material. This increased energy results in a more vigorous dissolution process and a faster material removal rate, leading to a higher MRR. additionally, the observations show that the highest electrolyte concentration of 65g/L resulted in less overcut. This is because higher electrolyte concentration improves conductivity, ensures uniform current distribution, and provides better control over the electrochemical reactions.
