Optimizing Micro-EDM Drilling Performance in Titanium Alloys: A Fuzzy Logic Approach with Comparative Electrode Analysis

This study investigates the enhancement of Micro Electric Discharge Machining Drilling (mEDMD) performance on Titanium 6Al-4V using brass tubular electrodes (BTE) and silver-coated brass tubular electrodes (SCBTE). Focusing on the material removal rate (MRR) and tubular electrode wear rate (TEWR), the research applies a Taguchi experimental design complemented by a modified Taguchi method and fuzzy logic for optimized precision in results. Findings reveal that SCBTE significantly increases MRR and reduces TEWR compared to BTE, indicating its potential to enhance machining efficiency, reduce tool wear, and improve productivity in demanding industrial applications. This work highlights the advantages of SCBTE for high-precision manufacturing, particularly in sectors requiring stringent material and dimensional accuracy, such as medical implants and aerospace components.
