Natural fibre composites (NFCs) have great potential to replace glass-fibre reinforced plastics in component manufacturing processes of the aerospace, automotive and electronics industries to name a few. For this, drilling high-quality holes in the NFCs turns out to be necessary to facilitate the assembly of the parts to the main structure in order to obtain the final product. The drilling process for NFCs introduces induced damages that compromise their structural integrity. In this regard, an appropriate choice of cutting speed, federate and type setup is important to make good quality holes through flax/epoxy laminate structures. This work proposes an experimental study which examines the influence of the cutting parameters on the quality of the holes obtained after a drilling process, using a flexible setup (partially supported plaque), of flax/epoxy laminated plaques. The results show that the combination of low federate and high cutting speed minimizes the delamination factor. It is also possible to use drilling with partial support to produce good quality holes. Finally, in order to ensure that the performance, under bending stress, is not degraded by the drilling operation, mechanical tests show that the quality of the holes produced with the tested cutting parameters slightly affects the flexural strength and the elastic modulus of flexion.
