Abstract

© 2021, Springer Nature Switzerland AG.Nanocomposites have been discovered and researched for over 60 years due to their advanced characteristics such as mechanical, thermal and electrical properties compared to other materials (i.e., metals, ceramics and alloys). Among the most functional nanomaterials, polymer nanocomposites have found many industrial applications, especially as structural materials. Although near-net-shape (NNS) manufacturing processes could be employed to fabricate these materials, higher qualities in terms of machine surface and dimensional accuracy, especially in complex features are still required since they are crucial requirements in modern manufacturing. Therefore, machining seems to be an inevitable process and have found huge potential to generate high-precision products. However, machining of polymer nanocomposites is more severe than that of other materials due to their anisotropic, heterogeneous structure and high mechanical properties (i.e., high abrasiveness, fracture toughness, tensile strength) of their reinforcing constituents. These factors could result in low machined surface quality, typical damages introduced into the machined surfaces and tool wear acceleration. Therefore, investigation on machining behaviours of these polymer nanocomposites is necessary to provide suitable cutting conditions. This chapter addresses these materials’ machinability when using major machining processes, including conventional, non-conventional, and micromachining.
