There is a swift growth of high strength temperature resistant (HSTR) alloys such as Nitra-alloy, Waspa-alloy, Titanium-alloy, Inconal, Die-cast steel etc. Since, the properties of these alloy materials are high in hardness, toughness, and impact strength and temperature resistant, therefore, the machining of these materials by conservative methods is really complicated. The unconventional machining processes are most excellent matched to machine such alloys. This article presents, a

... ve survey of various research works addressing the machining of HSTR alloys through wire electric discharge machining. Being a very complex machining process and having a large number of control parameters which affect the important response parameters like MRR, surface roughness, geometry etc, many computation tools have been implemented to optimize the process, and expert systems are developed for future predictions. Thus, the present study is an attempt to give future directions and a comprehensive update data on WEDM of HSTR alloys.
