EXPERIMENTAL RESEARCH REGARDING THE MODELLING OF PROCESS PARAMETERS OF DIMENSIONAL PROCESSING THROUGH ELECTRICAL DISCHARGE MACHINING

Abstract

The processing by electric erosion is part of the most general category of the processing methods using concentrated energies, by which the material prelevation is discontinuously and cumulated produced, the dimensional processing activation being the cumulated result of some elementary erosion processes, temporary and spatially concentrated between a transfer object and a processed object. Therefore, the statistic experimental analysis of the experimental package refers to the processing of the steel using transfer objects made of materials like electrolytic copper, steel and graphite. We examined the statistic experimental modelling and optimization of some objective functions of the type processing productivity, the volume wear of the transfer object and especially the quality of the processed surface measured by the rigorous parameter Ra [μm].
