Nanocomposites are heterogeneous, so their properties are influenced by many factors, similar to traditional compounds. Owing to the anisotropic and nonhomogeneous composition of nanocomposites and the strong abrasion of their reinforced elements, they generally become “difficult-to-machine” materials and typically cause workpiece damage and very rapid wear on the tool. Conventional machining by turning, milling, and drilling could be suitable subject to appropriate tool design and operating conditions. These composites have diverse applications in many advanced industries, including automotive, nuclear, and aerospace. Machining of nanocomposites remains a challenge. Understanding machining methods; their deformation behavior during machining, without damaging the desirable properties; surface integrity of the resulting workpiece; and tool wear is important. In engineering applications, machining is crucial in completing the assembly of a component. This chapter describes nanocomposites and their current applications and future challenges and perspectives.

Often, composite material items are manufactured into near-net shapes. However, the final finishing of the component is done by machining to achieve the appropriate dimensions and geometric tolerances. Even secondary machining techniques could be utilized to obtain difficult profile composite materials. But due care is vital for the requisite efficiency and productivity in the machining procedure.
