Materials and Manufacturing Processes: Vol. Electric Discharge Grinding Unacademy,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 Shares. Rate these results. Electrical discharge grinding (EDG) and conventional abrasive grinding are two different methods to machine polycrystalline diamond (PCD) with different removal mechanisms. (973) 344 - 6721 info@globoequipment.com. MACHINING Beskrivning . a. The work piece is machined using a stream of electric sparks. Electrical discharge grinding. Electro-Discharge Machining (EDM) is one thermal energy based process where material is removed by localized melting and vaporization. Electrical Discharge Grinding (EDG) and conventional grinding are two different processes with different removal mechanisms and are typically used to machine Polycrystalline Diamond (PCD). TOPIC: WIRE ELECTRICAL Presentation on advance technology i.e Wire Electrical Discharge Grinding... Looks like you’ve clipped this slide to already. This is the reason why it is considered non-traditional contrary to, for example, the processing with cutting tools. Electric discharge machining (EDM), or spark erosion is originally a high-precision manufacturing process. Back to Top. See our Privacy Policy and User Agreement for details. ELECTRICAL DISCHARGE Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. 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). On SlideShare. Electrical discharge machining, or EDM, is a non-traditional method in which material is removed from a workpiece using thermal energy. An investigation was made into the combined technologies of electrical discharge machining and grinding (EDMG). Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). The electrical discharge generates large amounts of heat. You can't see that sparks but I thought it was quite cool to see the dielectric flushing in slow motion(taken at 5000fps). 6,000°C c. 10,000°C d. 14,000°C (Ans:c) 4. 2,000°C b. The tool consists of a disc [1], which rotates around its horizontal axis. 32, No. WHAT IS EDM? Dr. V. B. Pansare 0 From Embeds. 0 Number of Embeds.
