In this process, a thin metallic wire is fed on to the conducting work piece, which is submerged in a tank of dielectric fluid such as deionised water. Wire is fed in the programmed path & material is cut from the work piece accordingly. Material removal takes place by a series of discrete discharges between the wire electrode & work piece in the presence of a dielectric fluid.
The dielectric fluid gets ionised in between the tool electrode gap, thereby creating a path for each discharge. The area wherein discharge takes place gets heated to very high temperature such that the surface get melted & removed.
The cut particles (debris) get flushed away by continuous flowing dielectric fluid. Generally, wire-cut EDM is used for cutting aluminium, brass, etc. and wire material used for quicker cutting action is zinc coated brass wires.

In a wire-cut EDM process, the necessary conditions that have to be me...
Introduction:
In the wire-cut EDM (Electrical Discharge Machining) process, a high-frequency electric spark is used to erode and cut through a workpiece. The process involves a wire electrode, usually made of brass or tungsten, which acts as a tool to shape the workpiece. The wire is guided through the workpiece, creating a narrow gap where the spark occurs.
Explanation:
To achieve a successful cut in wire-cut EDM, certain conditions need to be met. Among the given options, the correct condition is that both the wire and the workpiece should be electrically conducting.
Why wire and sample should be electrically conducting:
1. Electrical Discharge: The wire-cut EDM process relies on the generation of electrical discharges or sparks between the wire and the workpiece. These discharges occur in the small gap between the wire and the workpiece, creating intense heat that melts and vaporizes the material. This process is only possible when both the wire and the workpiece can conduct electricity.
2. Path for Current Flow: Electrical current needs a conductive path to flow. When both the wire and the workpiece are electrically conducting, the current can easily flow through them, creating the necessary conditions for the electrical discharge to take place.
3. Efficient Erosion: The electrical discharges cause localized heat, melting, and vaporization of the workpiece material. The conductive nature of both the wire and the workpiece ensures efficient erosion and material removal during the cutting process.
4. Stability and Control: When both the wire and the workpiece are electrically conducting, it allows for precise control of the cutting process. The electrical parameters, such as voltage and current, can be adjusted to achieve the desired cutting speed, surface finish, and accuracy.
Conclusion:
In the wire-cut EDM process, the necessary condition for making a successful cut is that both the wire and the workpiece should be electrically conducting. This ensures the generation of electrical discharges, efficient material removal, and precise control of the cutting process.
