1. Setup:

   • Workpiece: The material to be cut is mounted on the machine's worktable. The workpiece must be conductive, such as metals like steel, aluminum, and copper.
   • Wire Electrode: A thin wire, usually made of brass or copper, is threaded through the workpiece. The wire is continuously fed from a spool and is kept taut.

2. Electrical Discharge:

   • Discharge Process: A series of rapid electrical discharges (sparks) are generated between the wire and the workpiece. These sparks erode the material in the desired shape.
   • Dielectric Fluid: The process occurs in a bath of dielectric fluid (typically deionized water) that helps to cool the wire and workpiece and flush away debris.

3. CNC Control:

   • Programming: The machine is controlled by a computer numerical control (CNC) system. The desired cutting path is programmed into the machine, and the CNC system precisely controls the movement of the wire and the workpiece.
   • Movement: The CNC system directs the wire and workpiece according to the programmed specifications, allowing for complex geometries and high precision.
