What is Wire EDM CAM

The technology of EDM (Electro Discharge Machining) has been around for more than 100 years. It was first found by an American, Joseph Henry. This process is a extremely efficient and precise method of cutting, drilling and etching metals. The primary benefit of using this approach is that it does not need heat or pressure to cut through materials.

This method is used in various fields such as aerospace, vehicle, medical, military, durable goods, and so on. This method is also called Electro Machining. There are lots of kinds of EDM makers which are available in the market. They are broadly categorized into 2 types, manual and automatic. Handbook EDM is generally utilized for small tasks where there is no requirement for high precision.

Automatic EDM machines are primarily utilized in big scale jobs where there is a need for high precision. These machines are rather pricey and require high maintenance expenses. Among the most crucial benefits of EDM over other machining processes is that it is less susceptible to mistakes and can offer better accuracy. Another important advantage of EDM is that it can produce complex shapes.

EDM devices are essentially based upon two 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 existing. The latter usages chain reaction between the electrode and the workpiece to eliminate the metal.

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

EDM can be carried out in either air or water. When it comes to air, the workpiece is put inside a vacuum chamber and then the wire is fed into the chamber. Water EDM is carried out in a tank filled with water. The workpiece is put in the tank and the wire is placed into the water. In both cases the workpiece need to be electrically conductive.

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

• The voltage applied to the electrode

• The kind of wire being utilized

• The kind of workpiece being utilized

• The distance 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 level of the wire

The above discussed aspects impact the efficiency of the machine. Thus, in order to get excellent results, it is important to comprehend the fundamental principles of EDM.
