FIG.1
[0001] The present invention provides a method for preparing a copper graphene nanocomposite coated aluminum alloy, more particularly, to the copper graphene nanocomposite electrode for electro-discharge machining (EDM).
[0002] Electro-discharge machining (EDM) is a non-conventional machining process for cutting any conductive material irrespective of its hardness. The performance of the electro-discharge machining (EDM) process for efficient cutting relies on various properties like electrical conductivity, thermal conductivity, and resistance to heat of an electrode. The higher these properties lead to developing more current within a shorter time and it can be easily delivered to a workpiece with the help of a spark.
[0003] Conventional electrodes like copper, brass, graphite, and their alloys are generally used in electro-discharge machining (EDM) for machining different hard materials. However, the high cost and the high tool wear rate (TWR) of these conventional electrode leads to create problem while machining with EDM.
