Performance analysis of wire EDM process on aerospace materials

Abstract

Wire cut EDM is a non-traditional machining process, is used to machine hard materials. Wire electrode is one of the main factors that evaluate the performance of wire EDM which develops a vast performance. In this work, hard materials like Inconel and Titanium alloys are to be cut with combination of different parameters using a Brass electrode and their surface quality, Metal removal rate (MRR) will be analysed. The outcomes of various parameters such as pulse ON time, pulse OFF time and wire tension are the input parameters on surface quality to be studied. The results were observed that there was an increase in Metal removal rate with increase in pulse ON time and Input power and with the increase in pulse OFF time the Metal removal rate value decreases gradually. It has been found that surface roughness is reduced with enhance in pulse OFF time. Enormous concern has to be taken in constructing equally.
