摘要：Currently, the electrical discharge machining is mainly applied to obtain surfaces difficult to be obtained using other machining processes in the workpieces made of electroconductive materials. The electroerosion process involves the initiation of electrical discharges in the zones where there is the lowest electrical resistance between the tool electrode and the workpiece. The study of the asperities peaks behavior under the action of the electric discharges would allow a better understanding of gradual developing of the surfaces generated by the electroerosive process. A way of addressing this problem could be based on the use of a device that would allow the study of the influence exerted by some process input factors on the results of a single electrical discharge developed between the test piece sharp peak and the tool electrode. The formulation of the functional requirements and the application of some methods of stimulating the technical creativity and of selecting solutions on the basis of predetermined criteria allowed the definition of a principle solution corresponding to an experimental device applicable for studying the behavior of sharp peaks under the action of single electrical discharges.
