Among the various types of metal matrix composites, SiC particle-reinforced aluminum matrix composites (SiC p /Al) are finding increasing applications in many industrial fields such as aerospace, automotive, and electronics. However, SiC p /Al composites are considered as difficult-to-cut materials due to the hard ceramic reinforcement, which causes severe machinability degradation by increasing cutting tool wear, cutting force, etc. To improve the machinability of SiC p /Al composites, many techniques including conventional and nonconventional machining processes have been employed. The purpose of this study is to evaluate the machining performance of SiC p /Al composites using conventional machining, i.e., turning, milling, drilling, and grinding, and using nonconventional machining, namely electrical discharge machining (EDM), powder mixed EDM, wire EDM, electrochemical machining, and newly developed high-efficiency machining technologies, e.g., blasting erosion arc machining. This research not only presents an overview of the machining aspects of SiC p /Al composites using various processing technologies but also establishes optimization parameters as reference of industry applications.

“…Both failure criteria and mechanical behaviors are different from homogeneous materials during the machining process. The material is a kind of typical difficult-to-machine material, which is easy to cause numerous surface defects and rapid tool wear rate in cutting process [7][8][9][10][11]. All of these make the machining of SiCp/Al composites challenging.…”

SiC reinforced aluminum matrix composites (SiCp/Al composites) are typical difficult-to-machine material, and the irregular SiC particles diffused in SiCp/Al composites make the surface quality worse. In this paper, a single-point cutting investigations with finite element simulation were conducted for 65% SiCp/Al composites and aluminum alloy. The surface morphology characteristics of SiCp/Al composites, which mainly include breaking, part breaking, pulling out, protruding, al tearing, and interface debonding, are different from those of aluminum alloy materials. The high-volume SiC particles lower the surface quality and profile dimensional accuracy of SiCp/Al composites. There are thin and discrete layers covered on the machined surface.

High-speed grinding experiments of particle reinforcing titanium matrix composites ((TiCp + TiBw)/Ti-6Al-4V) were carried out with vitrified cubic boron nitride wheel and electroplated cubic boron nitride wheel, at the wheel speed ranged from 80 to 140 m/s. The cutting behavior, that is, grinding force, grinding temperature, specific grinding energy, and ground surface morphology, and grinding chips are analyzed. The results indicate that compared to the workpiece speed and the depth of cut, the wheel speed has a more significant influence on the grinding forces. The grinding temperature and specific grinding energy obtained with the vitrified cubic boron nitride wheel are always larger than those with the electroplated cubic boron nitride wheel. Based on the comprehensive consideration in terms of grinding force, grinding temperature, and specific grinding energy, the electroplated cubic boron nitride wheel is more suitable than vitrified cubic boron nitride wheel for high-speed grinding particle reinforcing titanium matrix composites. The removal of the reinforcements of particle reinforcing titanium matrix composites is mainly by means of pullout, fracture or crushing, micro-cracks, voids, and smearing. The segment chips containing the reinforcements are formed during high-speed grinding of particle reinforcing titanium matrix composites.
