Study regarding the productivity and quality obtained by means of various processing methods by means of electro-erosion

Abstract

This paper has the purpose to draw a comparative analysis regarding the processing productivity, the dimensional precision and the surface roughness by (EDM) processing with negative electrode and outlining (EDM) processing. For this purpose there will be used two different technological methods which will be presented in detail in relation to their stages. The experimental part will follow the obtained deviations as a result of the processing of a piece which has the same form and dimension. The main purpose of this paper is to establish the situations in which it is efficient to use one or another of the methods presented here.
