Question

In a wire-cut EDM process the necessary conditions that have to be met for making a successful cut are that

Correct answer (B) wire and sample are electrically conducting Solution In Electrical Discharge Machining (EDM), including wire-cut EDM, material removal occurs through a series of discrete electrical sparks between the tool (the wire) and the workpiece (the sample). For these sparks to occur, both the tool and the workpiece must be electrically conductive to complete the electrical circuit. Therefore, both the wire and the sample must be electrically conducting. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
