What is Wire EDM CAM

The technology of EDM (Electro Discharge Machining) has been around for more than 100 years. The primary benefit of utilizing this method is that it does not require heat or pressure to cut through materials.

There are numerous types of EDM machines which are offered in the market. Manual EDM is generally utilized for small jobs where there is no requirement for high accuracy.

Automatic EDM devices are primarily used in large scale jobs where there is a need for high accuracy. One of the most crucial advantages of EDM over other machining procedures is that it is less prone to mistakes and can offer better precision.

EDM devices are basically based on two technologies, wire discharge machining and electrochemical machining. The previous involves melting the metal and then removing it from the electrode through the action of electrical existing. The latter uses chemical reaction in between the electrode and the workpiece to eliminate the metal.

Wire EDM is among the best techniques for performing the above mentioned jobs. The procedure involves placing a wire with size in between 1 and 20 microns into a machining cell. The wire imitates a cutting tool and removes material from the workpiece. This procedure is very similar to wire cutting except that the wire is moving. In this case the wire acts like a torch. The speed of the wire identifies the quality of the cut. The speed of the wire is between 5 to 25 m/s. A typical wire size has to do with 1.5 micron. This wire needs to be flexible and ought to be able to flex easily.

In the case of air, the workpiece is placed inside a vacuum chamber and then the wire is fed into the chamber. The workpiece is put in the tank and the wire is placed into the water.

In addition to these, there are many other aspects which identify the quality of the cut. A few of them are:

• The voltage applied to the electrode

• The type of wire being used

• The kind of workpiece being used

• The distance between the wire and the workpiece

• The type of dielectric fluid being used

• The frequency of the electrical present

• The kind of tool holder

• The temperature level of the wire

The above discussed aspects impact the performance of the device. Thus, in order to get excellent outcomes, it is important to comprehend the fundamental principles of EDM.
