Modelling Of Micro Wire-EDM

Mishra, Ashutosh (2012) Modelling Of Micro Wire-EDM. BTech thesis.



The objective of the present work is to calculate the metal removal rate (MRR) during a single spark micro WEDM process using finite element analysis in ANSYS software. The material used is Inconel 625.
Wire electrical discharge machining (WEDM) is a thermoelectric metal removal process which erodes material from the work piece by a series of discrete sparks between the metal wire electrode and the workpiece, immersed in a dielectric liquid medium. The spark discharges generated between the electrode and the workpiece result in complex two dimensional and three dimensional shapes along a numerically controlled path. The purpose of micro WEDM is to achieve better accuracy and stability while dealing with small sized workpieces.
Finite element method (FEM) modelling is a computer-aided technique for finding approximate solutions of partial differential equations and integral equations.
