摘要

In order to improve geometric tolerance in complicated forms, this research thoroughly examines the optimization of electrical discharge machining (EDM) parameters. The research encompasses an analysis of various parameters including tool wear, wear ratio, material removal rate (MRR), angularity, and parallelism, all pivotal for achieving precise geometric tolerance. Utilizing a sophisticated 3D copper electrode for machining Al 7075 aluminum material, owing to copper’s more conductivity for electricity. Taguchi’s analysis is used in the study to determine the optimal combinations of sparking parameters, such as pulse off time, pulse on time, current, and dielectric pressure. The outcomes of the experiment show improvements in geometric tolerance, tool wear rate, wear ratio, MRR and, highlighting the possibility of EDM process optimization.
