The machining of titanium alloys by traditional methods causes many disadvantages of both technical and economic nature. These materials are characterized by very low thermal conductivity and belong to hard to machine materials. When machining these materials with conventional methods, there is a problem of chips thermal softening and increased tool wear. During machining, e.g. milling despite intensive cooling, the performance achieved is low. Although traditional processes of titanium alloys treatment pose many problems, the use of this strong and lightweight materials is still evolving. The aim of this article was to present the issue of wire electrical discharge machining of Titanium alloy Ti6Al4V. In particular, the comparison of brass wire and non-consumable molybdenum electrode and flushing techniques were analyzed. The relationship between the overheating of the machined surface layer and the magnitude of stresses and the formation of micro cracks on the machined surface was discussed. Based on its own research and the presented analysis of the literature on the subject, future directions of further research were indicated. An attempt should be made to investigate how flushing efficiency affects the machined shape, structural changes and chemical composition of the titanium alloy’s surface layer.
