What is Electrical Discharge Machining and how does it work?

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 why it is considered non-traditional contrary to, for example, the processing with ...

Abrasive Electrical Discharge Grinding - AML - Home

Abrasive Electrical Discharge Grinding (AEDG) . Introducing mechanical effects into EDG process leads to increase in metal removal rate. For example, in the case of Al-SiC composite, removal rate of the AEDG process (t e = 10 m s, and n = 500 rpm) is about 5 times greater than that of EDM process, and about twice of EDG process.

Electrochemical Machining (ECM) - Working Principle ...

Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl).

Electrical Discharge Machining - an overview ...

Electrical Discharge Machining. Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid. From: Machining and machine-tools, 2013.
