What is Wire EDM CAM

The innovation 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 really effective and accurate method of cutting, drilling and engraving metals. The main benefit of using this approach is that it does not need heat or pressure to cut through materials.

This technique is utilized in numerous fields such as aerospace, automobile, medical, military, consumer goods, etc. This approach is likewise called Electro Machining. There are lots of types of EDM devices which are readily available in the market. They are broadly classified into two types, handbook and automated. Manual EDM is generally utilized for little jobs where there is no requirement for high precision.

Automatic EDM devices are primarily utilized in big scale projects where there is a requirement for high precision. These makers are rather pricey and need high maintenance expenses. Among the most crucial advantages of EDM over other machining processes is that it is less prone to errors and can supply much better precision. Another crucial advantage of EDM is that it can produce complicated shapes.

EDM devices are essentially based upon 2 technologies, wire discharge machining and electrochemical machining. The former includes melting the metal and then removing it from the electrode through the action of electrical current. The latter usages chain reaction between the electrode and the workpiece to eliminate the metal.

Wire EDM is one of the finest techniques for performing the above discussed jobs. The wire acts like a cutting tool and eliminates material from the workpiece. The speed of the wire identifies the quality of the cut.

EDM can be carried out in either air or water. In the case of air, the workpiece is placed 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 put 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 figure out the quality of the cut. Some of them are:

• The voltage applied to the electrode

• The type of wire being utilized

• The type of workpiece being used

• The distance in between the wire and the workpiece

• The type of dielectric fluid being used

• The frequency of the electrical current

• The kind of tool holder

• The temperature level of the wire

The above discussed aspects affect the performance of the machine. Hence, in order to get great outcomes, it is necessary to comprehend the fundamental principles of EDM.
