What is Wire EDM CAM

The technology of EDM (Electro Discharge Machining) has actually been around for more than 100 years. It was first discovered by an American, Joseph Henry. This procedure is a really efficient and precise method of cutting, drilling and engraving metals. The main benefit of using this approach is that it does not need heat or pressure to cut through products.

There are lots of types of EDM makers which are readily available in the market. Manual EDM is mainly used for small jobs where there is no requirement for high accuracy.

Automatic EDM devices are mainly used in large scale jobs where there is a requirement for high accuracy. One of the most essential advantages of EDM over other machining procedures is that it is less susceptible to mistakes and can provide much better accuracy.

EDM machines are basically based on 2 technologies, wire discharge machining and electrochemical machining. The former includes melting the metal and then removing it from the electrode through the action of electric current. The latter uses chemical reaction between the electrode and the workpiece to remove the metal.

Wire EDM is one of the best techniques for performing the above mentioned tasks. The wire acts like a cutting tool and removes product from the workpiece. The speed of the wire identifies the quality of the cut.

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

In addition to these, there are lots of other elements which identify the quality of the cut. Some of them are:

• The voltage applied to the electrode

• The type of wire being used

• The type of workpiece being utilized

• The range 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 of the wire

The above pointed out elements impact the performance of the device. Therefore, in order to get good results, it is very important to comprehend the standard concepts of EDM.
