Abstract:

Titanium alloys are commonly used in industry, automotive, medical and all manufacturing applications.Unconventional machining process which offers lesser micro structural changes and less internal stresses produced during machining compare to traditional machining process. In this project Titanium Grade 5 alloy is machined by using WEDM process with different feed rates and the mechanical property changes are to be investigated. WEDM has since the process' launch emerged as the best option to manufacture micro parts with the highest degree of dimensional precision and surface finish consistency from a simple way to manufacture instruments and die. The machining parameters like kerfs width, material removal rate, feed rate, wire speed, wire tension and voltage are the factors influencing the mechanical properties and micro structure changes. Out of these parameters, the feed rate is varied and the properties like hardness, surface finish and micro structure changes are to be investigated and the best suitable feed rate for machining the titanium grade 5 alloy is to be identified.

Keywords:

Titanium alloy, WEDM, Material removal rate, SEM analysis, Hardness.
