Nanocomposites (both heterogeneous and anisotropic) are hard to machine due to their enhanced properties and there is a need to know about the problems associated with the machining of nanocomposites by various conventional as well as non-conventional machining operations. Machining of nanocomposites emphasizes on different fabrication methods to develop nanocomposites (polymers, metals, and ceramics) and different machining processes used in industries.
