Popis: Tool wear rate (TWR) in EDM has a direct effect on machining accuracy and production costs. Many new electrode materials have been introduced to improve TWR, and electrodes sprayed with refractory alloys are said to be new research directions with its prospects as well. In this study, the research team compared TWR of coated and uncoated electrodes in EDM for Ti-6AL-4 V titanium alloy. The basic electrode material is aluminum, and the coating material on the electrode surface is AlCrNi. Process parameters including current (I), gap volt (Vg), pulse on time (TON) were surveyed via Taguchi method. The results showed that TON and I are strongly influencing the TWR of both electrodes. The TWR of Al electrode is approximately 24% larger than that of coated Al electrode.
