Analysis of Energy Distribution in Sinker EDM Process
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 12
Abstract
Electro Discharge Machining (EDM) is used for machining electrically conducting /semi conducting, tough and brittle material .This process is best suited for making intricate cavities and contour, dies, section of complex geometry, moulds. The work piece material selected for this study is mild steel and tool is copper electrode. Dielectric flow rate, discharge current, pulse on time, pulse off time is considered as input parameters. In the present work ANOVA analysis is used to study the significance of process variable on Material Removal Rate (MRR) and Tool Wear Rate (TWR) by using simple conduction equations, we can calculate the energy transferred to each for material removal rate and tool wear rate. Also energy transferred to work piece, tool and dielectric fluid can be calculated by using conduction equation, convection equation, energy carried away by debris, and the best suited input parameters can be found for the maximum energy transfer to work piece. After than energy responsible for tool wear were calculated and the optimum parameter are found in order to minimize the tool wear The energy distribution in the electrical discharge machining (EDM) process is most important phenomenon for study the variation of fraction of input discharge energy with the help of thermo-mathematical models during EDM of mild steel by varying the machining parameter current and pulse duration.
