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 process is a very efficient and precise technique of cutting, drilling and inscribing metals. The primary benefit of using this approach is that it does not need heat or pressure to cut through materials.

This technique is utilized in various fields such as aerospace, vehicle, medical, military, durable goods, and so on. This method is likewise called Electro Machining. There are numerous kinds of EDM devices which are readily available in the market. They are broadly classified into two types, manual and automated. Handbook EDM is mainly used for little tasks where there is no requirement for high accuracy.

Automatic EDM makers are primarily used in large scale tasks where there is a need for high precision. One of the most crucial benefits of EDM over other machining processes is that it is less prone to errors and can supply better precision.

EDM machines are generally based on two technologies, wire discharge machining and electrochemical machining. The previous includes melting the metal and then removing it from the electrode through the action of electrical existing. The latter usages chain 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 discussed tasks. The procedure includes positioning a wire with diameter in between 1 and 20 microns into a machining cell. The wire imitates a cutting tool and eliminates material from the workpiece. This procedure is very comparable to wire cutting other than that the wire is moving. In this case the wire acts like 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 typical wire diameter is about 1.5 micron. This wire needs to be versatile and should be able to flex quickly.

EDM can be done in either air or water. In the case of air, the workpiece is positioned inside a vacuum chamber and after that the wire is fed into the chamber. Water EDM is performed in a tank filled with water. The workpiece is placed 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 numerous other aspects which identify the quality of the cut. Some of them are:

• The voltage applied to the electrode

• The kind 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 present

• The type of tool holder

• The temperature of the wire

The above discussed aspects affect the performance of the maker. Hence, in order to get excellent results, it is necessary to understand the basic principles of EDM.
