Wire EDM uses a very thin wire (sometimes a fraction of the width of a human hair) as the electrode. Electrical discharges arc from this wire to the work surface, as it is slowly fed through the metal. These discharges erode the metal as the wire passes through it to a an amazing tolerance of .0002 of an inch. The whole process is computer controlled, allowing for this degree of precision.
EDM wire cutting process could be considered complementary to conventional machining methods, because it is possible to produce accurate parts with complex shapes, which are more difficult to be made by conventional methods. EDM wire cutting process has the ability to cut delicate shapes from any conductive material, including hard materials, titanium, zirconium, etc. It was determined that

conversely, aerospace shops use wire EDM to cut large, heavy, highly complex parts. However, having to remove either of these types of workpieces from machines to check and verify them significantly in-creases the risk of errors, as well as adds to overall part cycle times. With in-process gauging on their wire EDMs, shops can check and verify parts before and after the EDM process and without

discussed wire EDM cutting for gears very often, there are various benefits to the process for gear manufacturing, one of which is that it is not as complicated as using a slew of cutters specific to the gear parameters required. “With wire EDM, all we need is an NC program of the tooth form and the blank that needs the teeth cut on it,” Langenhorst says. Investing in software specific to
Wire cutting EDM Extrusion dies and blanking punches are very often machined by wire cutting. In the machining area, each discharge creates a crater in the workpiece (material removal) and an impact on the tool (wear of the tool/electrode).

production process. Th ese include wire and electrode diameter, handling and ﬁ xturing, inspection, programming and machine settings. Let’s look brieﬂ y at each. Wire size. Standard EDM wire is 0.25mm in diameter. Microwires can range from 0.15mm down to 0.020mm. Th e wire diam-eter chosen depends on part features, such as corner radii, slot widths, thin-wall details and intricacy of
Wire cut EDM or Electrical Discharge Machining is a technique used to slice through metal. The technique uses thin brass wire for the purpose and can create intricate profiles with the process. The EDM machine uses spark discharges that are fast, repetitive, and controlled for cutting. This process works with electrically conductive metals. The process is specially suited for contours and

Common Wire Problems & Troubleshooting Wire EDM Resin. Whats the real story?water jet i Failure) The purpose of edm mixed bed resin is to maintain a constant condition of conductivity based on the work material being cut. The process of edming has the inherent effect of raising conductivity. Therefore it is important to have good filtration and a properly operating resin system to insure good
Optimisation of wire-cut EDM process parameter by Grey-based response surface methodology March 2018 Wire electric discharge machining (WEDM) is one of the advanced machining processes.
The process is burr-free, distortion-free and can be used to machine exotic materials which are work-hardened, ductile or brittle. As the axis of this wire can be rotated, taper-cuts, free-curves and complex geometries can be achieved with exceptionally straight profiles, allowing components to be stacked for low-mid volume production.
