Enhancement of Surface Finish of Shape Memory Alloy Using Electrical Discharge Machine

Abstract

Electro discharge machine is basically used to machine complex profile or hard material which cannot be machine or difficult to machine using traditional machines. Shape memory alloys have super elastic characteristic, so it is very difficult to machine by traditional machines. In this study, themain aim is to enhancement of surface finish of shape memory alloy using Electro discharge machine. For this experiment conducted and results are analyses using statistical analysis methods such as Taguchi method. For experimentation four factors are selected such as gap voltage, discharge current, pulse on time, and pulse off time and analyses response such as surface roughness. For analysis L₉Taguchi orthogonal array used. Finally from statistical technique optimum process parameters are calculated and validate with experimentally.
