What are some examples of machining processes that fall under the Electro Thermal classification?

EDM (Electrical Discharge Machining), LBM (Laser Beam Machining), PAM (Plasma Arc Machining), and EBM (Electro Beam Machining)

What is the main energy source used in EDM (Electro Discharge Machining)?

Electric energy

How is the tool and the work piece connected in EDM?

The tool is connected to the (-) voltage as the cathode, while the work piece is connected to the (+) voltage as the anode.

What role does the dielectric fluid play in EDM?

The dielectric fluid acts as an insulator until the potential is sufficiently high, a cooling medium, and a flushing medium to carry away the removed metal particles. Signup and view all the answers

What are some advantages of EDM?

Energy is applied at the exact spot where the operation is to be carried out, no complicated fixtures are required to hold the work, and even very thin objects can be machined. Signup and view all the answers

What are some disadvantages of EDM?

Metal removal is slow, the work piece must be an electrical conductor, high power requirements, and surface cracking may occur in some materials. Signup and view all the answers
