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 procedure is a extremely efficient and precise method of cutting, drilling and inscribing metals. The main benefit of using this approach is that it does not require heat or pressure to cut through materials.

This technique is used in various fields such as aerospace, automotive, medical, military, consumer goods, etc. This method is likewise referred to as Electro Machining. There are lots of kinds of EDM makers which are readily available in the market. They are broadly classified into two types, manual and automatic. Manual EDM is generally used for small jobs where there is no requirement for high precision.

Automatic EDM makers are mainly used in big scale tasks where there is a need for high precision. These machines are quite pricey and need high upkeep expenses. Among the most crucial benefits of EDM over other machining processes is that it is less vulnerable to errors and can offer much better accuracy. Another essential benefit of EDM is that it can produce complex shapes.

EDM devices are basically based on 2 innovations, 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 chemical reaction in between the electrode and the workpiece to get rid of the metal.

Wire EDM is among the best techniques for performing the above pointed out tasks. The procedure involves positioning a wire with size between 1 and 20 microns into a machining cell. The wire acts like a cutting tool and gets rid of product from the workpiece. This process is really similar to wire cutting except that the wire is moving. In this case the wire imitates a torch. The speed of the wire figures out the quality of the cut. The speed of the wire is between 5 to 25 m/s. A typical wire size is about 1.5 micron. This wire needs to be flexible and ought to be able to flex easily.

EDM can be carried out in either air or water. In the case of air, the workpiece is put inside a vacuum chamber and after that the wire is fed into the chamber. Water EDM is done in a tank filled with water. The workpiece is placed in the tank and the wire is inserted into the water. In both cases the workpiece should be electrically conductive.

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

• The voltage applied to the electrode

• The type of wire being utilized

• The type of workpiece being utilized

• The range 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 level of the wire

The above discussed factors impact the efficiency of the machine. Hence, in order to get great outcomes, it is very important to understand the basic concepts of EDM.
