Modelled and Experimental Analysis of Electrode Wear in Micro Electro Discharge Machining with Carbon Fibres
This paper presents an analysis of electrode wear in a micro electro discharge machining with carbon fibres as tool electrodes. Experimental data are discussed and compared with theoretical calculations. Both approaches are focusing on a frequency of discharges impact on the process. The thermal model is presented because melting and evaporation are main phenomena occurring in EDM process. Basing on certain assumptions and simplifications the approximated depth of single discharge crater can be estimated. The experimental data indicating a strong dependence between electrode wear parameter and energy. It also presents a tendency of this parameter in comparison with a frequency of discharges.
