5-axis CNC wire EDM is the greatest innovation usually called as the revolutionary machining process affecting the modern machine tool and precision machining industries. WEDM has acquired improvements to the machining industry in product accuracy, quality and profitability. In the early stages, costly conventional processes were frequently used in the production, however, now with the aid of computer numerical controlled WEDM machines, intricate, complex shape and hard materials (Hardened D2, Tungsten Carbides, high carbon tool steel, composites etc.) can be machined automatically and precisely at low costs. Components having superior properties, higher surface finish, precise and close tolerances are the most important requirements in industries and to achieve these requirements, highly precise, non-conventional machining processes are preferred. This paper presents the review of 5-axis CNC WEDM, its developments, experimental analysis, literature survey for optimization of WEDM process parameters and its effect on the properties and performance parameters of the materials.
