EDG Electric Discharge Grinding. In the present work conditions, the processes like conventional diamond grinding, electric discharge machining (EDM), and electric discharge grinding (EDG) are compared on the basis of material removal rate (MRR) and surface finish (Ra).electric discharge machining (EDM), and electric discharge grinding (EDG) are
sharp cutting edge although its machining efficiency is extremely low. In order to improve the material removal rate when manufacturing PCD tools, electrical discharge grinding (EDG), a variation of electrical discharge machining (EDM) process but with a rotational electrode, is now gradually be adopted in industry to manufacture PCD tools.
Electric Discharge Grinding (EDG) EDG is similar to EDM except that the electrode is a rotating wheel (usually graphite). Positively charged work pieces are immersed in or flooded by a dielectric fluid and fed past the negatively charged wheel by servo controlled machine table charged wheel by .

The material removal rate for EDG has been modelled based on material removal rates for grinding and EDM processes. ... (grinding, EDM or combination of the two) has been identified for MRR. ...
However, the beneficial properties of high hardness and high strength cause problems in shaping SiC blanks. Electrical discharge machining (EDM) is one of the most popular unconventional machining processes used for producing hard and brittle material. But, the processing efficiency of EDM is lower than electrical discharge grinding (EDG).

Jan 06, 2015· Electrochemical discharge grinding Electrochemical discharge grinding (ECDG) is a hybrid process of electrochemical machining (ECM) and electrical discharge grinding (EDG). It is used for the machining of electrically conductive materials. This process uses nonabrasive graphite grinding wheel with no abrasive particles and an electrolyte.
Nov 21, 2008· Electrical discharge machining (EDM) and electrical discharge grinding (EDG) of conducting ceramic show lower cost. With the help of some assisting methods, WEDM, EDM and EDG can be used to machine insulating ceramics. However, EDM and EDG of a large surface area on insulating ceramics show lower efficiency.
Keywords: Electrical discharge grinding; Gap control; Dual stage actuator INTRODUCTION Electrical discharge machining/grinding (EDM/EDG) is widely used to machine the parts of aerospace, automotive and mould, which are often made in those difficulttomachine materials, such as polycrystalline diamond (PCD) and tungsten carbide [1, 2].
Electrical discharge grinding (EDG) is becoming more prevalent in the manufacturing of polycrystalline diamond (PCD) tools. This paper concerns investigation of the effects of machining parameters, as well as finishing infeed, to the surface quality obtained when using EDG to erode PCD.
Therefore, in the present work, the processes like conventional diamond grinding, electric discharge machining (EDM), and electric discharge grinding (EDG) are compared on the basis of material removal rate (MRR) and surface finish (Ra). EDG is the hybrid process of EDM and grinding and hence utilizes the benefits of both processes to give ...

Abrasive Electrical Discharge Grinding (AEDG) . Introducing mechanical effects into EDG process leads to increase in metal removal rate. For example, in the case of AlSiC 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.
ELECTRIC DISCHARGE DIAMOND GRINDING (EDDG) Hybrid process involves machining of hard materials using advantages of EDM as well as conventional grinding. Water or waterbased cutting fluid is used as dielectric. Metal bonded diamond grit wheel is used in place of a simple electrically conductive wheel (graphite) used in EDG.
