Different Types of Wires Effects on Wire Cut EDM Machine by D.O.E. Approach

Abstract

At present Industrial application needs the use of advanced materials like tool steels, super alloys, ceramics, and composites with high precision and high surface quality. These materials are hard and difficult to machine. To meet these challenges, non-conventional machining processes are being employed to achieve higher metal removal rate, better surface finish and greater dimensional accuracy.

Wire cut EDM is most progressive non-conventional machining process in mechanical industries. There are so many parameter affect the performance of Wire cut EDM. Few of them are investigated in this report. In present an attempt is made to investigate the effect of varying pulse on time, pulse off time, wire feed rate and Peak current on H-11 material to analyze effect on the Kerf Width (KW) and Material Removal Rate (MRR) using ANOVA analysis and multi response Taguchi base optimization will be carried out. A Taguchi design of experiment (DOE) approach with L9 Orthogonal Array employed to conduct this experiment. The ANOVA calculation by both Mathematical steps and Minitab software.
