What is Wire EDM CAM

The technology of EDM (Electro Discharge Machining) has actually been around for more than 100 years. The main advantage of using this technique is that it does not need heat or pressure to cut through products.

This method is used in different fields such as aerospace, automobile, medical, military, durable goods, etc. This technique is also known as Electro Machining. There are many kinds of EDM devices which are offered in the market. They are broadly classified into 2 types, handbook and automated. Manual EDM is mainly used for small jobs where there is no requirement for high precision.

Automatic EDM makers are mainly used in big scale tasks where there is a need for high accuracy. One of the most essential advantages of EDM over other machining procedures is that it is less prone to errors and can offer much better precision.

EDM machines are generally based on 2 technologies, 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 usages chain reaction between the electrode and the workpiece to eliminate the metal.

Wire EDM is one of the best methods for performing the above discussed jobs. The procedure includes positioning a wire with diameter between 1 and 20 microns into a machining cell. The wire imitates a cutting tool and removes product from the workpiece. This procedure is really similar to wire cutting except that the wire is moving. In this case the wire imitates a torch. The speed of the wire determines the quality of the cut. The speed of the wire is in between 5 to 25 m/s. A normal wire size has to do with 1.5 micron. This wire must be flexible and need to be able to flex easily.

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

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

• The voltage applied to the electrode

• The kind of wire being utilized

• The kind of workpiece being used

• The range 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 mentioned factors affect the performance of the maker. Hence, in order to get great outcomes, it is essential to understand the basic principles of EDM.
