What is Wire EDM CAM
The technology of EDM (Electro Discharge Machining) has been around for more than 100 years. The primary benefit of using this method is that it does not require heat or pressure to cut through materials.
There are many types of EDM devices which are readily available in the market. Handbook EDM is mainly utilized for small jobs where there is no requirement for high accuracy.
Automatic EDM devices are generally used in big scale jobs where there is a need for high accuracy. One of the most essential benefits of EDM over other machining procedures is that it is less vulnerable to mistakes and can offer better accuracy.
EDM machines are basically based upon 2 technologies, wire discharge machining and electrochemical machining. The previous includes melting the metal and then removing it from the electrode through the action of electrical present. The latter uses chain reaction in between the electrode and the workpiece to eliminate the metal.
Wire EDM is one of the best methods for performing the above mentioned jobs. The wire acts like a cutting tool and removes material from the workpiece. The speed of the wire identifies the quality of the cut.
In the case of air, the workpiece is placed 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 numerous other aspects which determine the quality of the cut. A few of them are:
• The voltage applied to the electrode
• The type of wire being used
• The kind of workpiece being utilized
• The range in between the wire and the workpiece
• The kind of dielectric fluid being utilized
• The frequency of the electrical current
• The type of tool holder
• The temperature of the wire
The above discussed factors impact the efficiency of the device. Hence, in order to get great outcomes, it is important to understand the fundamental principles of EDM.
