Recently CFRP has been focused in a variety of new applications such as precision electrical components, surgical tools and biomedical devices because of its light-weight and excellent mechanical property. However, the form accuracies of the mechanical features generated by traditional CFRP fabrication methods are limited to meet the requirements of microcomponents. Furthermore, due to the difficulties in mechanical machining of CFRP in microscale, sometimes alternative material removal method is required in production of precision devices. Micro-electrical discharge machining (EDM) has been used for manufacturing of microholes and 3D micromolds of metal workpieces because of its machining accuracy and non-contact machining characteristics. In this study, we have implemented micro-EDM to the precision machining of CFRP substrates that are also a conductor. Proper EDM conditions for microhole drilling of CFRP for precision component fabrication with micro features were studied. Experiments on micro-EDM machinability were performed using a commercial micro-EDM tool. A variety of machining parameters were tried such as open circuit voltage and maximum current. Material removal rate (MRR) and tool wear ratio (TWR) were compared with respect to experimental conditions.
