The machining of thin and fragile material is very difficult for manufacturing industries and rapid demand of requirement could not be achieved. Electrical discharge machining is more acceptable machine tool for machining hard and brittle electrically conductive materials but its productivity is very slow. In past decade, researchers are focus on electrical discharge …
Electrical discharge grinding (EDG) is much like electrical discharge machining except that the electrode (tool) is a rotating graphite wheel. This article commences with a schematic illustration of a setup for EDG wheels and discusses the control operation of the EDG setup. It tabulates typical applications and conditions for the EDG of ...
Abstract Electrochemical discharge grinding (ECDG) is a combination of electrochemical grinding (ECG) and electrical discharge grinding (EDG), with some modification of each. This article commences with a schematic illustration of a setup for ECDG using a …
INTRODUCTION WEDG (wire electro discharge grinding) technique is a special version of the micro WEDM method that was introduced firstly by Masuzawa et al. (1985) The WEDG process is considered as a finishing process where the purpose is to obtain good surface quality In WEDG no mechanical contact nor cutting is necessary for surface finish.
Electrochemical discharge grinding (ECDG) is a combination of electrochemical grinding (ECG) and electrical discharge grinding (EDG), with some modification of each. This article commences with a schematic illustration of a setup for ECDG using a solid bonded graphite wheel. It describes the process characteristics of ECDG in terms of current ...

Electro-Discharge Grinding. Electro-Chemical Grinding. EDG is not a hybrid process. ECG is one hybrid process. It is one thermal energy based non-conventional machining process. ECG is based on electro-chemical energy as well as mechanical energy. Here material removal takes place by melting and vaporization due to intense localized heat ...

HISTORY OF EDM In1770s, discovered by Joseph Priestly. Developed in the mid 1970s In the mid 1980s, the EDM techniques were transferred to a machine tool Today,it is a viable technique that helped shape
Electrical discharge grinding. Abrasive machining method where controlled spark discharges from an electrically charged, rotating wheel grinds the workpiece surface. Beskrivning . The process. The tool consists of a disc [1], which rotates around its horizontal axis.
Whereas material is removed in the form of solid micro-chips in grinding, EDG follows the principle of melting and vaporizing the material with the assistance of high intensity spark. Various similarities and differences between traditional grinding and electro discharge grinding (EDG) are given below in table format.

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.
