Özet
This study investigates the machinability of Ti–6Al–4V alloy using electro discharge turning (EDT), with particular focus on the effects of current (I p), pulse duration (T on), and workpiece rotational speed (v) on process performance. While conventional evaluation metrics such as material removal rate (MRR) and tool wear rate (TWR) were considered, a novel metric, the deviation of section area (DA), was introduced to provide deeper insights into the dimensional accuracy of the process. The introduction of DA is expected to improve understanding of the complex physical phenomena inherent to EDM-based processes. Experimental results were analyzed using response surface methodology (RSM), yielding statistical models and regression equations. The findings highlight the critical influence of process parameters on machining performance, demonstrate the potential of EDT as an effective method for machining Ti–6Al–4V alloys, and establish DA as a promising performance indicator for future studies.
