Effects of flushing on electrical discharge machining and

Both electrical discharge machining and electro-arc machining are non-contact machining processes, which use high temperatures produced by discharges to erode material. The gap between the tool and the workpiece is usually filled with liquid dielectric medium.

What is Electrical Discharge Machining and how does it

Electrical discharge machining, or EDM, is a non-traditional method in which material is removed from a workpiece using thermal energy. Much like processes such as laser cutting, EDM does not need mechanical force in the removal process. This is the reason

Electrical discharge machining has advantages over other machining techniques due to its ability to create complex and intricate parts with a high degree of accuracy. Another advantage of electrical discharge machining is its ability to machine parts on an extremely small scale.

What is Electrical Discharge Machining (EDM)?

Die sinking EDM or Ram EDM is an attractive option when complex cavities need machining. Firstly, a graphite electrode is produced in the reverse shape to the required cavity to form the die. The process works by inducing a voltage between the die and the electrically conductive workpiece while being submerged in a dielectric fluid.
