What is Wire EDM CAM

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

This technique is utilized in different fields such as aerospace, automotive, medical, military, durable goods, etc. This technique is likewise referred to as Electro Machining. There are many types of EDM makers which are readily available in the market. They are broadly categorized into 2 types, manual and automated. Handbook EDM is mainly used for small tasks where there is no requirement for high accuracy.

Automatic EDM devices are primarily used in big scale jobs where there is a requirement for high accuracy. One of the most important benefits of EDM over other machining procedures is that it is less vulnerable to errors and can offer better precision.

EDM devices are essentially based upon 2 innovations, wire discharge machining and electrochemical machining. The former involves melting the metal and then removing it from the electrode through the action of electric current. The latter uses chemical reaction in between the electrode and the workpiece to get rid of the metal.

Wire EDM is one of the finest techniques for carrying out the above discussed jobs. The wire acts like a cutting tool and gets rid of material 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 put in the tank and the wire is inserted into the water.

In addition to these, there are lots of other elements which determine the quality of the cut. Some 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 existing

• The kind of tool holder

• The temperature of the wire

The above discussed elements affect the efficiency of the machine. Hence, in order to get great results, it is very important to comprehend the basic principles of EDM.
