Workpieces made of highly rigid dielectric materials with high precision engineering is an urgent problem. Use for this method of electrical discharge machining requires the creation of certain conditions under which it becomes possible to form the breakdown channel between the electrode - tool and the workpiece. This work is devoted to the analysis of modern technology process of electrical discharge machining of dielectric materials. The basic principle of channel formation breakdown in these technologies is a technique of creating an artificial material conductivity. Availability of erosion products in the conductive electrode gap contributes to the electric discharge, which in turn starts microportions embossing material from the surface of the dielectric piece. From the analysis of existing techniques that for EEE dielectrics need to create a border – held layer between the workpiece and the electrode-tool. The above techniques prove the possibility of processing dielectrics by electrical discharge machining.
