ELECTRO CHEMICAL MACHINING AND ELECTRICAL

SUMMARY In this paper current developments in various aspects of electrochemical and electro-discharge machining is presented in this paper. ECM and EDM technologies have been successfully adapted to produce macro, micro components with complex features and high aspect ratios for biomedical and other applications.

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

Layer Depth Constrained Servo Scanning EDM for 3D

Micro electro discharge machining (EDM) is capable of forming complex 3D microstructures by a rod-like tool electrode to scan layer-by-layer. The scanning 3D micro EDM has the special advantages of low setup cost, design freedom and easy removal of chips.

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.
