What is Wire EDM CAM

The innovation of EDM (Electro Discharge Machining) has been around for more than 100 years. The primary benefit of using this approach is that it does not require heat or pressure to cut through materials.

This method is utilized in numerous fields such as aerospace, vehicle, medical, military, durable goods, and so on. This method is likewise called Electro Machining. There are many kinds of EDM machines which are offered in the market. They are broadly categorized into two types, handbook and automated. Manual EDM is primarily utilized for little jobs where there is no requirement for high accuracy.

Automatic EDM machines are mainly utilized in big scale tasks where there is a requirement for high precision. These makers are rather costly and require high maintenance costs. One of the most crucial advantages of EDM over other machining processes is that it is less susceptible to mistakes and can offer better accuracy. Another crucial benefit of EDM is that it can produce complicated shapes.

EDM machines are essentially based on two innovations, wire discharge machining and electrochemical machining. The former involves melting the metal and after that removing it from the electrode through the action of electric current. The latter usages chemical reaction between the electrode and the workpiece to remove the metal.

Wire EDM is one of the best methods for carrying out the above discussed tasks. The wire acts like a cutting tool and removes material from the workpiece. The speed of the wire determines the quality of the cut.

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 carried out 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 must be electrically conductive.

In addition to these, there are many other factors which determine the quality of the cut. A few of them are:

• The voltage applied to the electrode

• The kind of wire being used

• The kind of workpiece being utilized

• The range in between the wire and the workpiece

• The type of dielectric fluid being used

• The frequency of the electrical present

• The type of tool holder

• The temperature of the wire

The above pointed out factors affect the performance of the device. Therefore, in order to get good results, it is very important to understand the standard concepts of EDM.
