What is Wire EDM CAM

The innovation of EDM (Electro Discharge Machining) has actually been around for more than 100 years. It was first discovered by an American, Joseph Henry. This process is a really effective and accurate technique of cutting, drilling and engraving metals. The main advantage of using this technique is that it does not require heat or pressure to cut through materials.

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

Automatic EDM machines are mainly utilized in large scale tasks where there is a need for high accuracy. One of the most crucial benefits of EDM over other machining processes is that it is less vulnerable to mistakes and can provide better precision.

EDM machines are generally based on two technologies, wire discharge machining and electrochemical machining. The former involves melting the metal and then removing it from the electrode through the action of electrical existing. The latter uses chemical reaction between the electrode and the workpiece to remove the metal.

Wire EDM is one of the best approaches for carrying out the above pointed out jobs. The wire acts like a cutting tool and removes product from the workpiece. The speed of the wire figures out the quality of the cut.

EDM can be carried out in either air or water. In the case of air, the workpiece is put inside a vacuum chamber and then the wire is fed into the chamber. Water EDM is done in a tank filled with water. The workpiece is positioned in the tank and the wire is inserted into the water. In both cases the workpiece must be electrically conductive.

In addition to these, there are many other factors which determine the quality of the cut. Some of them are:

• The voltage applied to the electrode

• The kind of wire being used

• The type of workpiece being used

• The range in between the wire and the workpiece

• The kind of dielectric fluid being used

• The frequency of the electrical existing

• The type of tool holder

• The temperature of the wire

The above pointed out aspects affect the efficiency of the maker. Therefore, in order to get good outcomes, it is necessary to understand the fundamental concepts of EDM.
