PARAMETRIC OPTIMIZATION ON DIE STEEL USING WIRE CUT EDM

Abstract

Wire cut EDM is one of the non-traditional machining processes. Machining parameters affecting quality
characteristics in the machining process is thoroughly studied. In this present study AISI 52100 is used as a work piece.
The input parameters selected for optimization pulse on time, pulse off time, voltage and wire feed. Dielectric fluid
pressure, wire tension, resistance and cutting length are taken as fixed parameters. The experimental of the Taguchi L32
has been used. For each experiment material removal rate, surface roughness and kerf width was determined by using
contact signal to noise ratio measuring system respectively. By using multi objective optimization technique Grey
Relational Analysis, in order to optimize the input parameters in wire EDM for AISI 52100. The Analysis of variance is
too useful to identify the most important factor. The objective of optimization is to attain the maximize the material
removal rate, minimize the surface roughness and minimize the kerf width.
