“…The plan assumes the high and low level of each of the input parameters ( Table 2). The values of each level were chosen based on preliminary tests in which the process with single carbon fibres was able to be performed [11,12,17,19].…”

“…The form of the electrode can also serve as a link between micro and macro features of machined shapes as it is possible to chose appropriate size of the tool electrode by gathering right number of single fibres to create desired tool dimension. Although the wear of single carbon fibre electrodes was noticeable, in a sense of linear shortening of a tool, what was reported in [17], it still enabled to perform the machining [17]. Multifilament electrodes with higher conductivity due to larger cross-section (μm 2 -single fibre vs. mm 2 -multifilament rod) should significantly change the wear of the tool and give also a possibility of manufacturing structures in wider range of diameter.…”

“…In many cases to obtain better machining output and lower tool electrode wear new materials are tested [7,11,12,15,17,19,22,26,27]. Usually, in most applications, standard electrodes made of graphite, copper or other metals are considered [3,5].…”

“…Single carbon fibres that have been considered as electrode material in [11,12,17,19] have above-mentioned properties at acceptable level and can be used in electroerosive conditions. In this study, however, the new approach to the use of carbon fibres as tool electrodes is presented.…”

“…The electrodes in a form of multifilament rods are proposed and examined. They can be considered as similar material to previously tested single carbon fibres [11,12,17,19] but their form should enhance the process output. The form of the electrode can also serve as a link between micro and macro features of machined shapes as it is possible to chose appropriate size of the tool electrode by gathering right number of single fibres to create desired tool dimension.…”

The aim of the study was to verify the possibility of application of multifilament carbon fibre electrodes for electrical discharge machining process. In the article, the novel type of tool electrode in form of a rod that is composed of carbon fibres was proposed. The performed analysis taking into account the influence of input parameter from RC generator like voltage, capacitance and resistance along with evaluation of the process with this novel type of electrodes was considered. The manufacturing technique was assessed by analysing the geometry parameters of machined holes like diameters and maximum depth. The detailed analysis and quantitative values of the impact of each of the input factors were presented and response surfaces according to the experimental methodology were obtained. The key efficiency parameter which was expressed by material removal rate (MRR) was also calculated and compared with data for other materials used as tool electrodes that were presented previously in literature. The comparison study proved that with multifilament carbon fibre electrodes the comparable range of MRR parameter in similar electro-erosive conditions can be obtained. Thus, they can be considered as complementary material for tool electrode purposes.

The aim of this work is to analyse the influence of electrode material in micro-EDM drilling of stainless steel and tungsten carbide metal plates. Brass and tungsten carbide electrodes were selected basing on their different electrical and thermal properties. The experimental campaign was based on the execution of a large number of micro-holes carried out by varying some process parameters, namely peak current, voltage and frequency. Tool wear ratio and material removal rate were assumed as process performance indexes, while diametral overcut and taper rate were considered as geometric indexes. The Analysis of Variance (ANOVA) was applied on the results coming out from the experiments. Moreover, a overall Process Index based on both process parameters and electrode material properties was proposed. This index fits, with a good correlation level, all the process performance and geometric indicators for both the considered workpiece materials. A comparison between the performance measured using stainless steel and tungsten carbide workpieces was also carried out. The results of this experimental research showed that electrical resistivity, thermal conductivity and melting point of both electrode and workpiece materials have a significant effect on the process and geometric performance.
