Electrical discharge grinding (EDG) is a non-traditional thermal process for machining hard and brittle electrically conductive materials. EDG has been developed by replacing the stationary electrode used in electrical discharge machining (EDM) with …

WHAT IS WEDG ? WEDG(wire electrical discharge grinding) is material removing process to obtain batter surface finish. It is a type of grinding use for grind micro precise component. 5. WORKING:- The WEDG process, illustrated in …

Electrical Discharge Grinding (EDG) and conventional grinding are two different processes Abstract with different removal mechanisms and are typically used to machine Polycrystalline Diamond (PCD). This paper addresses the quality issue of PCD tools produced by these two processes in machining sharp cutting edges.

Abstract Electrical discharge grinding (EDG) and conven- tional abrasive grinding are two different methods to machine polycrystalline diamond (PCD) with different removal mech- anisms. This paper discussed the quality issues of PCD tools produced by the two processes. Although remarkably similar

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.

termed electrical discharge diamond grinding (EDDG) utilizes a metal bonded diamond-grinding wheel and subjects the work to the simultaneous influence of dia-mond grains and electrical sparks which cause abrasion and surface melting, respectively. Electrodischarge dressing is a new method for dress-

Introduction Electrical discharge grinding (EDG) is a is not always beneficial and after a certain value of non-traditional thermal process for machining hard speed, the spark becomes instable and produces and brittle electrically conductive materials. EDG …

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.

Electrical discharge grinding (EDG) and conventional abrasive grinding are two different methods to machine polycrystalline diamond (PCD) with different removal mechanisms. This paper discussed the quality issues of PCD tools produced by the two processes. Although remarkably similar surface roughness and tool sharpness were obtained in both processes, it …

This paper reports on experimental investigation of the electrical discharge diamond grinding process that combines mechanical grinding with electrical discharge machining. In this process, the workpiece is simultaneously subjected to heating, by electrical sparks bridging the gap between the metallic wheel bonding material and the work, and abrasion by diamond grains.

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 ...

The spark discharges facilitate grinding by thermally softening the work material in the grinding zone, and consequently decreasing the nromal force. It is observed that the material removal rate increases with an increase in current and pulse on-time, while it decreases with an increase in voltage and duty factor.
