Abstract

Many composite materials with superior mechanical properties including a high strength-weight ratio are titanium alloys. Titanium alloys. But, these alloys’ machinability is weak. Some non-conventional processing techniques for machining these alloys have been found to be useful. Machinery to cut hard metals such as titanium for wire electro-discharge (WEDM) is a method used to create complex shapes. Machinery to cut hard metals such as titanium for wire electro-discharge (WEDM) is a method used to create complicated shapes. In this research work a clear and wider knowledge on WDEM and its process parameters along with the effect of material feed rate, surface topography and residual stress.
