Abstract:The machinability of graphene-reinforced magnesium-based hybrid nanocomposites produced through the application of powder metallurgy method has not been completely reported. This article presents an experimental investigation on the thrust force, the surface roughness (R a ), and drilled surfaces characteristics in the drilling process of a Mg/SiC/GNPs (magnesium matrix based silicon carbide and graphene nanoplatelets) hybrid magnesium matrix composite. The hybrid composite material was produced through the application of a powder metallurgy method. The experiments were carried out with uncoated, PVD (Physical Vapor Deposition), and CVD (Chemical Vapor Deposition) coated tungsten carbide drill bits at three levels of cutting speeds (30, 40, and 50 m/min), and three different levels of feed rate (0.10, 0.15, and 0.20 mm/rev) under dry machining conditions. Taguchi's L 27 (3 3 ) orthogonal array and S/N ratio were used to optimize the optimal parameters for thrust force and surface roughness. The experimental results indicated that the thrust force and the surface roughness were extremely dependent on a particular type of drill bits, feed rate, and cutting speed. The feed rate parameter is known to have a significant influence on the surface finish.

“…These composites are not uniform in structure and have a mechanical behavior that is different form that of uniform materials. [28][29][30] The SiC particle has high yield strength and its elastic modulus is very high, whereas the standard aluminum alloy has low yield strength and good plasticity. Under force, the stress of the matrix is unequal to that of reinforcing particles.…”

The dynamic material model (DMM) method has been widely used for the macroscopic description of flow, fracture, and workability of materials under hot deformation. This investigation is aimed at proposing a new methodology for the optimization of hot machinability of a material using the DMM stability criteria. The constitutive flow behavior of Al-20 pct SiC has been evaluated in the temperature range 50°C to 350°C and the cutting velocity in the range from 25 and 300 m/min with the view to optimizing its machinability using the DMM instability parameters. The DMM instability parameters predicted a narrow region around 150°C and 150 m/min as the optimum domain for machining this material. It has been observed that the tool wear is minimum at optimal conditions. This investigation proved that the machinability could be optimized through the DMM.

“…Tool wear is also related to delamination, as the force necessary to cut the material increases with tool wear [11][12][13]. Many authors have studied the tool wear process for drilling carbon composites as well as the effect of tool wear on the drilling forces and quality of the holes produced [14][15][16][17][18][19].…”
