What is Wire EDM CAM

The innovation of EDM (Electro Discharge Machining) has actually been around for more than 100 years. It was first found by an American, Joseph Henry. This procedure is a extremely efficient and accurate technique of cutting, drilling and inscribing metals. The primary advantage of using this technique is that it does not require heat or pressure to cut through materials.

There are many types of EDM machines which are available in the market. Handbook EDM is mainly used for little jobs where there is no requirement for high accuracy.

Automatic EDM devices are primarily utilized in big scale jobs where there is a need for high precision. One of the most essential benefits of EDM over other machining processes is that it is less vulnerable to mistakes and can provide better precision.

EDM machines are generally based upon 2 innovations, wire discharge machining and electrochemical machining. The previous involves melting the metal and after that removing it from the electrode through the action of electric current. The latter uses chain reaction in between the electrode and the workpiece to remove the metal.

Wire EDM is one of the very best methods for carrying out the above pointed out jobs. The procedure involves placing a wire with size in between 1 and 20 microns into a machining cell. The wire imitates a cutting tool and removes material from the workpiece. This procedure is extremely 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 is about 1.5 micron. This wire should be flexible and must have the ability to flex quickly.

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 placed in the tank and the wire is inserted into the water.

In addition to these, there are numerous other elements which identify the quality of the cut. Some of them are:

• The voltage applied to the electrode

• The type of wire being used

• The type of workpiece being utilized

• The distance in between the wire and the workpiece

• The kind of dielectric fluid being utilized

• The frequency of the electrical current

• The kind of tool holder

• The temperature of the wire

The above pointed out elements affect the efficiency of the device. Hence, in order to get great results, it is very important to understand the basic concepts of EDM.
