Unlike conventional metal cutting processes, non-traditional machining (NTM) processes can directly employ different forms of energy for controlled removal of material from the workpiece to impart desired shape, size and finish. Three layers must be removed or modified in case of highly stressed applications. No residual stresses will be generated because no forces are acting. But the limitation faced by this type of machining process is high cost of operation. 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). Ans. : Advantages: (i) Material removal rates ranges from 0.16 to 2.54 cm 3 /min and surface finishes in the range of 1.6 to 3.2 μm R a are possible. This article commences with a schematic illustration of a setup for ECDG using a solid bonded graphite wheel. Explain the advantages and applications of Electric Discharge Grinding (EDG) over conventional grinding. These are some advantages of using Electrical Discharge Machining: The machining process does not depend on the mechanical properties of the workpiece. Although remarkably similar surface roughness and tool sharpness were obtained in both processes, it was found that residual stress and … The process variants electrical discharge turning (EDT), electrical discharge grinding (EDG), and wire electrical discharge grinding (WEDG) are compared with respect to the influence by the above-mentioned effects and the resulting process planning. Electric discharge machining, also known as spark erosion, electro-erosion or spark machining is a process of metal removal based on the principle of erosion of metals by an interrupted electric spark discharge between the electrode tool cathode and the work anode. https://www.hitekmfg.com/electrical-discharge-machining-edm-services.html The advantages of the multistage machining is the reduction of manufacturing time. To compensate with very low material removal rates resulted by EDM new processes like Electric Discharge Grinding (EDG) which integrates the phenomenon of electric discharge machining and mechanical grinding leading to good surface quality were developed. Electrochemical discharge grinding (ECDG) is a combination of electrochemical grinding (ECG) and electrical discharge grinding (EDG), with some modification of each. Electrical discharge grinding (EDG) and conventional abrasive grinding are two different methods to machine polycrystalline diamond (PCD) with different removal mechanisms. The deeper hole is possible to produce (L/D) up to 20. ABOUT WIRE ELECTRICAL DISCHARGE: Wire EDM in NJ, NY, and PA. EDG - Electric Discharge Grinding.
