A metal matrix (Cu/SiC p) electrode with a rotating device was made and employed to study the EDMG technology.It was found that 3–7 times the normal electrical discharge machining (EDM) material removal rate (MRR) could be achieved in EDMG under suitable conditions of … The electrical parameters are discharge voltage, pulse Fig. Much like processes such as laser cutting, EDM does not need mechanical force in the removal process. Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges (sparks). EDG (Electro Discharge Grinding) 23. melting and vaporization) but the construction resembles the conventional grinding process. See our Privacy Policy and User Agreement for details.

Electric discharge machining (EDM), sometimes colloquially also referred to as spark machining, spark eroding, burning, die sinking or wire erosion, is a manufacturing process whereby a desired shape is obtained using electrical discharges (sparks). Phone Number. 127-134. In Electrical discharge machining; a potential difference is applied across the tool and w/p in pulse form. The Hybrid-µEDM -DT110 developed in Singapore, as shown in Fig. The electrical discharge generates large amounts of heat. The aim of this study was to find a method to precisely measure the individual diamond crate morphology during the electrical discharge process. The effects of wheel speed, open circuit voltage, peak current, pulse on time, and pulse off time of EDG on the material removal rate (MRR), wheel wear rate (WWR) and surface roughness (SR) are investigated respectively. Erosion takes place both on Work piece and the tool. Electric Discharge Grinding (EDG) is one thermal energy based non-traditional machining process that has apparent similarity in construction with the conventional grinding process. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. T… The mechanism of material removal in electric discharge grinding (EDG) is very complex due to interdependence of mechanical and thermal energies responsible for material removal. Presentation by, 0. a. Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges (sparks).

Instead of a stationary form electrode as used in EDM, a wheel electrode made of conductive material is used in EDG. Thin sections (abrasive wheel where pressure might cause distortion) 3. Clipping is a handy way to collect important slides you want to go back to later. This is the reason why it is considered non-traditional contrary to, for example, the processing with cutting tools. Nomenclature EDC Electrical Discharge Conditioning Fn Normal force [N] Ft Tangential force [N] TB time break, pause time [μs] 2. The electrical parameters are discharge voltage, pulse Fig. The tool consists of a disc [1], which rotates around its horizontal axis. Electrical Discharge Grinding (EDG) and conventional grinding are two different processes with different removal mechanisms and are typically used to machine Polycrystalline Diamond (PCD). Electro-Discharge Machining (EDM) is one thermal energy based process where material is removed by localized melting and vaporization. Copy to clipboard; Details / edit; Termium. Enrollment no.
