“…Since researchers found that chip adhesion plays an important role in determining the surface quality at high speed cutting, polycrystalline diamond (PCD) tool and its coating were studied and found that they exhibited an outstanding performance in machining of MMCs materials due to its high hardness and low chemical affinity with the MMCs materials [19]. Huang et al [20] conducted drilling experiment on Al/SiC p with high volume fraction (56 %). An extremely rapid flank wear was found on PCD drills and they concluded that the primary mechanism includes abrasive and adhesive wear.…”

As a composite material with combination of low weight and high engineering strength, metal matrix composites (MMCs) have been utilised in numerous applications such as aerospace, automobile, and bioengineering. However, MMCs are recognised as difficult-to-cut materials due to their improved strength and high hardness of the reinforcing particles. This paper presents an experimental investigation on micro-machinability of Mg-based MMCs reinforced with Ti and TiB 2 nano-sized particles. The tool wear of AlTiN-coated micro-end mills was investigated. Both abrasive and chip adhesion effect were observed on the main cutting edges, whilst the reinforcement materials and volume fraction play an important role in determining the wear type and severity. The influence of cutting parameters on the surface morphology and cutting force was studied. According to analysis of variance (ANOVA), depth of cut and spindle speed have significant effect on the surface roughness. The specific cutting energy, surface morphology and the minimum chip thickness was obtained and characterised with the aim of examining the size effect. Furthermore, higher cutting force and worse machined surface quality were obtained at the small feed per tooth ranging from 0.15 to 0.5 μm/tooth indicating a strong size effect. Overall, Mg/TiB 2 MMCs exhibit better machinability.

Nickel-silicon-chromium-copper (C18000) alloy is widely used for many precision applications due to its high thermal conductivity, hardness, and moderate strength in fabrication of parts of molds. This study was carried out on this material for achieving mirror finish and minimizing profile error. Four machine and tool parameters were varied at different levels in a single point diamond turning operation to create a spherical profile on the workpiece. The surface roughness and profile accuracy were significantly affected by tool nose radius, feed rate, and spindle speed and depth of cut had insignificant effect. The process was optimized separately for both surface roughness and profile accuracy. Increased tool nose radius caused a ripple like effect on the machined surface as compared to a digging effect with low or no tool nose radius and thus showed a better surface finish. The profile error, however, increased with tool nose radius. Subsequently, both surface roughness and profile accuracy were optimized together using grey relational grade to obtain a globally optimized solution. The final parameter setting in an optimal solution identified feed rate as the most significant parameter followed by nose radius and spindle speed. A surface roughness and profile error of 15 nm and 0.464 mm, respectively, was attained during the confirmation experiments.

“…Huang et al [171] reported that the thrust force varied linearly with the feed rate, while the cutting speed had no significant effect on the thrust force when drilling SiC p /Al composites with high-volume fractions (55%-57% SiC) and large particle sizes. Hu et al [172] developed a 3D finite element model for simulating the 3 mm diameter peck drilling behavior of SiC p /Al composites by using ABAQUS/Explicit.…”

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.
