The machining of hard composite materials causes serious tool wear due to the abrasive nature of reinforcement by conventional machining techniques. Therefore non- conventional machining techniques are used to machine such advanced materials. Wire cut electric discharge machining process is a non- conventional machining technique that fulfills the requirements of tooling and machining industries. Wire Electrical discharge machining (WEDM) has higher capability for cutting complex shapes with high precision for these materials without using high cost of cutting tools. The risk of wire bending and breakage is a serious problem, which reduce the efficiency and accuracy of the WEDM operation. The main causes of wire bending and breakage are energy between wire tool and work piece, dielectric fluid and wire material. This research paper highlights the review of the published work on WEDM which are related to energy, dielectric fluid and material of wire tool. The main purpose of this research paper is to investigate the effect of produced energy during operation, dielectric fluid and material of wire tool on the response parameters material removal rate, surface roughness and kerf width in wire electrical discharge machining (WEDM).
