Study and Experimentation for Process Parameters on Inconel 904L by using EDM
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 6
Abstract
EDM is an important and commercial method of machining very tough and brittle electrically conductive materials. It is broadly used in the process of making moulds and dies and sections of complex geometry and complicated shapes. The work piece material selected in this experiment is Inconel 904L taking because it’s widely usage in industrial applications. The input variables are Voltage, current and pulse on time. Taguchi L9 orthogonal array is applied to optimize the processes variable. The effect of the variable parameters mentioned above upon machining characteristics such as Material Removal Rate (MRR) and Surface Roughness (SR) is studied and investigated. The obtained results showed that current was the most significant parameter followed by voltage and pulse on time for the Material removal rate (MRR) and, for Surface roughness (Ra) current was the most significant parameter followed by pulse on time and voltage. The selected electrode material is cupper and duty cycle is 90% during the whole experiment.
