AB The novelty of EDM machining as a drilling operation for composite materials meansthat there is no consensus on the influence of the parameters that optimise the final quality. Forthese reasons, a characterisation of the EDM drilling process of a unidirectional composite materialhas been developed. The influence of several cutting parameters has been related to the quality ofthe final hole obtained. Thus, macrogeometric aspects in terms of conicity and final diameter andmicrogeometric aspects in terms of surface quality have been evaluated. In addition, the final stateof the material and the wear of the electrode have been evaluated by visual inspection, allowingthe range of cutting parameters that offer the best performance to be established. Finally, a series ofcontour diagrams based on predictive models have been obtained to establish a direct relationshipbetween input and output variables.
