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.
