What is Wire EDM CAM

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

This approach is utilized in different fields such as aerospace, automobile, medical, military, consumer goods, etc. This approach is also known as Electro Machining. There are numerous types of EDM machines which are available in the market. They are broadly categorized into 2 types, manual and automated. Manual EDM is primarily utilized for little tasks where there is no requirement for high accuracy.

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

EDM makers are essentially based upon two technologies, wire discharge machining and electrochemical machining. The previous involves melting the metal and after that removing it from the electrode through the action of electrical existing. The latter usages chemical reaction between the electrode and the workpiece to get rid of the metal.

Wire EDM is one of the best techniques for performing the above pointed out tasks. The process includes placing a wire with diameter in between 1 and 20 microns into a machining cell. The wire acts like a cutting tool and eliminates material from the workpiece. This procedure is really 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 normal wire size is about 1.5 micron. This wire needs to be flexible and ought to have the ability to bend easily.

EDM can be done in either air or water. In the case of air, the workpiece is put inside a vacuum chamber and after that 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 placed into the water. In both cases the workpiece should be electrically conductive.

In addition to these, there are lots of other elements which figure out 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 range in between the wire and the workpiece

• The kind of dielectric fluid being utilized

• The frequency of the electrical current

• The kind of tool holder

• The temperature level of the wire

The above mentioned factors affect the performance of the device. Hence, in order to get excellent outcomes, it is important to understand the standard concepts of EDM.
