What is Wire EDM CAM

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

This method is utilized in numerous fields such as aerospace, automobile, medical, military, consumer goods, and so on. This technique is likewise referred to as Electro Machining. There are numerous types of EDM machines which are available in the market. They are broadly classified into 2 types, manual and automated. Manual EDM is mainly used for little tasks where there is no requirement for high precision.

Automatic EDM devices are generally utilized in big scale tasks where there is a requirement for high precision. These makers are rather pricey and require high upkeep expenses. Among the most essential advantages of EDM over other machining procedures is that it is less prone to mistakes and can supply much better precision. Another essential benefit of EDM is that it can produce complicated shapes.

EDM devices are essentially based on 2 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 present. The latter usages chain reaction between the electrode and the workpiece to get rid of the metal.

Wire EDM is among the very best methods for performing the above discussed jobs. The process involves placing a wire with diameter between 1 and 20 microns into a machining cell. The wire imitates a cutting tool and removes material from the workpiece. This process is really comparable to wire cutting except that the wire is moving. In this case the wire acts like a torch. The speed of the wire figures out the quality of the cut. The speed of the wire is in between 5 to 25 m/s. A normal wire size has to do with 1.5 micron. This wire should be flexible and need to be able to flex easily.

In the case of air, the workpiece is put inside a vacuum chamber and then the wire is fed into the chamber. The workpiece is put in the tank and the wire is placed into the water.

In addition to these, there are many other factors 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 kind of workpiece being used

• The range in between the wire and the workpiece

• The type of dielectric fluid being utilized

• The frequency of the electrical current

• The type of tool holder

• The temperature of the wire

The above mentioned aspects impact the efficiency of the device. Hence, in order to get good results, it is very important to understand the standard principles of EDM.
