This scientific paper presents some aspects related to the management of the optimization of processing operations by electrical erosion with contact breaking. The introductory part contains a series of theoretical considerations on the approached field, highlighting the importance and role of optimizing such a process. The criteria for achieving an optimization process in this way, in the industry, as well as the restrictions imposed by them in optimizing the cutting are also analyzed. In the last part of the research are presented the own points of view and the conclusions derived from this study that point out the need to correlate the technological, mechanical and working parameters in the electrical erosion process. At the same time, the way in which this process can be improved in the sense of creating favorable conditions regarding its stability was highlighted. [ABSTRACT FROM AUTHOR]

Electrical erosion is one of the most common methods of processing with concentrated energy. In this way, the sampling method of the material is discontinuously and cumulative. The way in which the activation of dimensional processing is performed is effectively a cumulative result of erosion processes of an elementary and temporary nature and which is spatially concentrated. This concentration takes place between a transfer object and a processing object. In this context, this scientific paper highlights an experimental statistical analysis whose experimental set refers to the processing of sintered hard alloys of type P30. The transfer objects that were used were made of specific materials: electrolytic copper, steel and graphite. In this experimental study was examined the modeling and statistical optimization of some objective functions. These objective functions aim at the process productivity, the transfer objects volume and last but not least the quality of the surface that was processed, measured by the Ra [µm] parameter.
