PRESENTATION ON WIRE EDM PPT 2. Here the tool is negative and w/p is positive. Electrical Discharge Machining (EDM) The wire moves in a carefully controlled pattern, roughly analogous to a woodworker’s scroll saw, causing sparking to occur between the wire and the workpiece. EXPERIMENTAL STUDY A. We can use wire erosion to cut through conductive materials, such as titanium, aluminium and tungsten carbide. Electric Discharge Machining (EDM) PPT - Topics For Seminar. It works by electric breakdown; the enormous potential gradient between tool and work-piece pulls electrons free from molecules of the dielectric, and accelerates them into projectiles, kicking more electrons from molecules as they pass, thereby creating a cascade. 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. See our Privacy Policy and User Agreement for details. 2. In a Wire electric discharge machining a wire about (0.05-0.30mm diameter) is used as an electrode and deionized water as a materials.

Wire electrical discharge machining (WEDM) technology is a potential new candidate for silicon slicing, which can be compared with existing procedures to see if it can eventually substitute for the ID saw, or even compete with wire saws in some manufacturing orders (Figure 3.9). This is mainly due to the complicated stochastic process mechanisms in WEDM. Wire EDM works the same way standard Electro Discharge Machining (EDM). •EDM typically works with materials that are electrically conductive, although methods have also been proposed for using EDM to machine insulating ceramics. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes. Requires dielectric fluid, which creates a path for each discharge as fluid becomes ionized in the gap. The wire is fed from spool which is held guided between upper and lower side. •Electrical discharge machining is a machining method primarily used for hard metals or those that would be very difficult to machine with traditional techniques. As the potential difference is applied, electrons from the tool start to move towards the workpiece. Electro-Discharge Machining (EDM) is one thermal energy based process where material is removed by localized melting and vaporization.
