What is Wire EDM CAM

The technology of EDM (Electro Discharge Machining) has been around for more than 100 years. The main benefit of utilizing this method is that it does not require heat or pressure to cut through products.

There are many types of EDM machines which are readily available in the market. Handbook EDM is mainly used for little tasks where there is no requirement for high precision.

Automatic EDM devices are mainly utilized in big scale projects where there is a requirement for high accuracy. These devices are quite costly and need high upkeep costs. Among the most crucial advantages of EDM over other machining procedures is that it is less vulnerable to mistakes and can provide better accuracy. Another essential advantage of EDM is that it can produce complicated shapes.

EDM makers are generally based on 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 electric current. The latter uses chemical reaction between the electrode and the workpiece to eliminate the metal.

Wire EDM is among the very best methods for performing the above pointed out tasks. The procedure involves putting a wire with size in between 1 and 20 microns into a machining cell. The wire acts like a cutting tool and eliminates material from the workpiece. This process is extremely 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 common wire diameter is about 1.5 micron. This wire must be versatile and ought to be able to bend quickly.

EDM can be carried out in either air or water. When it comes to air, the workpiece is placed inside a vacuum chamber and then the wire is fed into the chamber. Water EDM is performed 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 need to be electrically conductive.

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 used

• The type of workpiece being used

• The distance 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 of the wire

The above discussed factors affect the performance of the device. Thus, in order to get good results, it is necessary to understand the basic concepts of EDM.
