Abstract

Wire Electrical Discharge Machining (WEPSPDM) is utilizedin industries to manufacture components of conductive strong metal with complicated shape, greater tolerance and precision. A review of the literature exposes that most of the research work has been intended for towards the optimization of WEDM operation and modeling of the process. Conventional wire electrode has been developed to a brass wire from a copper wire and finally to zinc coated wire on the brass, steel or copper wire core, by which more advanced WEDM, is realized in terms of better machining speed and accuracy. To examine the parameters likePeak Current (Ip ), Time of Pulse ON (Ton), Time of Pulse OFF (Toff), etc. by the optimization of WEDM operation and modeling of the process during micro slit machining. Analyzed the results and optimize the process parameter conditions for maximum MRR (g/min), and surface roughness based on Taguchi’s Methodology. The ANOVA analysis indicates the significant factors for maximization of MRR, improvement of Surface Roughness and regression analysis. By the research work, it has been concluded that the MRR reduces with raise in Time of Pulse OFF (Toff) and Set Voltage of spark gap (SV) besides Material Removal Rate (MRR) increases with escalating in Time of Pulse ON (Ton) and PC (IP).

Highlights

In Wire Electric Discharge Machining (WEDM)process the quality of product is always concerned by its procedural parameters such as wire feed, peak current time, time of pulse ON, time of pulse OFF etc
It was exposed through literature review that Design of Experiment (DOE) founded by Taguchi method was previously utilized by many seekers and present study is applying Taguchi method
WEDM process was experimentally solved in this study for wire cutting of using Regression Analysis (ANOVA) &Design of Experiment (DOE) were utilized further to get equations

Summary

INTRODUCTION

Process the quality of product is always concerned by its procedural parameters such as wire feed, peak current time, time of pulse ON, time of pulse OFF etc. Several research seekers were deeply go through the tested parameters. Numerous seekers were using Design of Experiment (DOE) for such kind of studies and identifies the finest factors which influences the obtained result. One simple work piece arrangement was used in this study and DOE was enforced to discover the best optimal input parameter value that alters the outcome result for specimen of WEDM. It was exposed through literature review that DOE founded by Taguchi method was previously utilized by many seekers and present study is applying Taguchi method.
