Optimization of Process Parameters of Titanium Alloy Grade 5 Using CNC Wire-Cut EDM

Abstract

Accompanying the development of mechanical industry, the demand for alloy materials having high hardness, toughness and impact strength are increasing. As these materials pose severe difficulty to be machined by conventional methods, Wire-cut Electric Discharge Machining (Wire EDM) machines are employed to machine them. The ultimate requirement of any machining process being fine surface finish, is accurately satisfied by wire-cut EDM process. Hence this project aims at obtaining the best surface finish by optimizing various process parameters affecting the machining conditions. With the assistance of Taguchi quality engineering, various number of experiments will be conducted by varying the process parameters at various levels. The output response variable being surface roughness, will be measured for all the number of experiments conducted. As the lowest value of surface roughness indicates the best surface finish, the optimum parameter level combination would be analyzed which gives desired surface finish. These optimized values of various parameters would then be used in performing machining operation in order to obtain desirable outputs.
