“…Among traditional machining process, grinding operation is important for PMMCs, since it could be applied for heavy-duty machining and obtaining desired dimensional tolerances and surface quality [6]. As the presence of hard reinforcement particles in PMMCs, wear of cutting tools aggravates and tool life sharply shortens, which increase the machining cost [7][8][9]. The low cost and high precision makes grinding important for the processing of PMMCs to obtain desired dimensional tolerances and surface integrity.…”

In situ TiB 2 particle-reinforced aluminum matrix composite (in situ TiB 2 /Al composites) is a new kind of metal matrix composite. With in situ synthesis method, a better adhesion at interfaces is achieved and hence improves mechanical properties. However, few literature focused on its grindability and surface integrity which limited its widespread use in industries. In this paper, the effects of grinding parameters and grinding wheels on the grinding performance of in situ TiB 2 /Al composites are investigated experimentally. The results show that the grinding performance is mostly affected by the wheel speed and grinding depth. The signal alumina wheel has the best grindability in grinding in situ TiB 2 /Al composites. Unlike other ex situ PMMCs, the in situ TiB 2 / Al composite is removed in a ductile-mode and pull-out or fractured particles are not found on the ground surface. Surface thermal softening effect and residual tensile stress indicate thermal effect dominate over mechanical effect in the grinding process. These results can be used to understand the material removal mechanism of grinding in situ TiB 2 /Al composites.

“…The damage of the tool cutting edge/flank was attributed to abrasion [18,[22][23][24] and pulled out of tool material grains from cutting edge and flank face of the tool [21]. It was also reported that flank wear increased with speed [25,26] and at high speeds, chipping of cutting edge became prominent [26]. Under these conditions, impact between particle and tool increases which induces easier fracture causing chipping at the cutting edge.…”

This paper investigates the particle fracture and debonding during machining of metal matrix composite (MMC) due to developed stress and strain, and interaction with moving tool by finite element analysis. The machining zone was divided into three regions: primary, secondary and tertiary deformation zones. The tendency of particles to fracture in each deformation zone was investigated. The findings of this study were also discussed with respect to the experimental results available in the literature. It was found that particles at the cutting path in the tertiary deformation zone fractured as it interacted with tool. In the secondary deformation zone, particles interacted with other particles as well as cutting tool. This caused debonding and fracture of huge number of particles as those were moving up along the rake face with the chips. No particle fracture was noted at the primary deformation zone. The results obtained from finite element analysis were very similar to those obtained from experimental studies.

“…Kılıckap et al (2005) examined homogenised 5% SiC-p aluminium MMC material was selected for experimental investigation of tool wear and surface roughness. Two types of K10 cutting tool (uncoated and TiN-coated) were used at different cutting speeds (50, 100 and 150 m min −1 ), feed rates (0.1, 0.2 and 0.3 mm/rev) and depths of cut (0.5, 1 and 1.5 mm).…”

Problem statement: Metal Matrix Composites (MMC) have become a leading material among composite materials and in particular, particle reinforced aluminum MMCs have received considerable attention due to their excellent engineering properties. These materials are known as the difficult-to-machine materials because of the hardness and abrasive nature of reinforcement elementlike Alumina (Al 2 O 3 ). Approach: In this study, an attempt has been made to model the machinability evaluation through the response surface methodology in machining of homogenized 10% micron Al 2 O 3 LM25 Al MMC manufactured through stir casting method. Results: The combined effects of three machining parameters including cutting speed (s), feed rate (f) and depth of cut (d) on the basis of three performance characteristics of tool wear (VB), surface Roughness (Ra) and cutting Force (Fz) were investigated. The contour plots were generated to study the effect of process parameters as well as their interactions. Conclusion: The process parameters are optimized using desirability-based approach response surface methodology.
