synthetic fibre based composites in many industrial applications. Machining is often necessary to
facilitate assembly of parts in a final product. This study focuses on a comparative experimental
analysis of the effects of conventional drilling (CD) and a hybrid ultrasonically-assisted drilling
(UAD) of a hemp fibre-reinforced vinyl ester composite laminate. The results obtained indicate
that UAD is more efficient when compared to CD for a range of drilling conditions. It yields
lower cutting forces and energy resulting in reduced machining-induced damage in the
composite, including diminished burr formation and fibre pull-outs. The holes drilled with UAD
exhibit improved surface finish and hole quality when compared to those produced with CD. The
study demonstrates the applicability of UAD as a viable machining process for improved
machinability of heterogeneous NFRP composite materials.
