Wire Cut Edm Process

As the wire is brought close the workpiece the electrical field increases as the distance squared.

Wire cut edm process.

Wire edm machining is an electro thermal production process where a thin single strand metal wire in conjunction with de ionized water used to conduct electricity allows the wire to cut through metal by the use of heat from electrical sparks. As the name implies wire edm uses a thin wire for an electrode. Wire electrical discharge machining wedm uses a metallic wire to cut or shape a workpiece often a conductive material with a thin electrode wire that follows a precisely programmed path. Eventually the dielectric material will reach a point where electrical breakdown occurs and sparks will fly across the gap between the wire and the workpiece thus.

This fine finish is present even after very large parts are cut as in figure 5 2. Wire edm is also known as. Wire edm produces an excellent finish even in the so called rough cut customers are often amazed when shown the fine finish of a single pass cut. It is a very precise method for the right applications such as for 2 axis cutting of small parts with tight tolerances at high volumes.

Electrical discharge machining edm also known as spark machining spark eroding die sinking wire burning or wire erosion is a metal fabrication process whereby a desired shape is obtained by using electrical discharges sparks. Extremely fine finishes of 12 rms can be produced with wire edm. This history of wire edm is less clear cut than die sinker edm but what is known is that it was developed over roughly a decade between the 1960s and 1970s as a new method for making dies from hardened steel. Wire edm cutting advantages.

With the wire edm cutting process controlled and rapidly repeating electrical charges are used to remove material from electrically conductive materials. Wire edm cuts without contact burr free. Wire cut edm is a specific kind of edm process and is one of the most common. Wire cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm.

Because of its versatility manufacturers use edm wire cutting machine operation for an extensive range of applications. Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes separated by a dielectric liquid and subject. Because the process can cut very small pieces it is often an ideal choice for the production of small highly detailed items that would normally be too delicate for other machining options. Because the wire is so fine you can cut small radius inside corners or even narrow slots.
