Question

EDM (Electric Discharge Machining) is suitable for:

• A. Plastic parts
• B. Hard conductive materials
• C. Wooden molds
• D. Composites

Hint:

Remember, EDM is only effective on conductive materials. It works well for hard metals and materials that are difficult to machine with traditional methods.

Answer 1

The Correct Option is B

Electric Discharge Machining (EDM) is a non-traditional machining process that uses electrical discharges (sparks) to remove material from the workpiece. It is primarily used for machining hard conductive materials such as tool steels, tungsten, titanium, and other high-strength materials that are difficult to machine using traditional methods.
- Plastic parts are typically not suitable for EDM, as the process requires conductive materials to create electrical discharges.
- Wooden molds are non-conductive and not suitable for EDM.
- Composites may not be suitable for EDM unless they contain conductive materials. EDM is most effective on metals and other conductive materials.
Thus, EDM is most suitable for hard conductive materials, making option (2) the correct answer.
