“…MMC with the larger size and high hardness of particle reinforcements caused higher pressure strength on the surrounding of particles due to the obstruction of plastic deformation, resulting in a fracture of particles. Besides, coarse particles may have more defects, which leads to rapid tool wear and worsens surface finish during machining as done by other researchers (Quan et al, 1999;Pramanik et al, 2008). It is concluded that the usage of carbide cutting tools is sufficient in machining of AlSi/AlN MMC with a smaller size of particle range of 1 to 2 µm.…”

In this paper, the tool life and wear mechanism of uncoated carbide tool and PVD TiAlN coated carbide are analyzed when end milling of AlSi/AlN metal matrix composite (MMC) with cutting speeds in the range of 240 m/min to 400 m/min. The results show that at all cutting speed conditions, wear mechanism is dominated by abrasion and adhesion due to the hard particles that adhere temporarily or permanently on the flank face of cutting tool and scratch the surface. As a result, the formation of grooves is observed, and particles of cemented tungsten carbide are pulled-out due to the collision between AlN and carbide at the higher cutting speed of 400 m/min. This high cutting speed had caused cracking on the cutting edge. BUE was formed and deposited on the rake face. In this study, it was found that cutting speed is the most significant factor which contributed 76% to the cutting tool life compared to the depth of cut (13.86%) and feed rate (5.63%). This is believed to be due to the reaction between cutting tool and AlSi/AlN MMC that will cause the increasing of cutting temperature and resulting in the tool wear of cutting tool.

“…When the reinforcing particle boundary is poor, the boundary crack occurs resulting in a shear-break cutting. If the shear deformation of the matrix is hindered by reinforcing particles, squeeze-break and collapse cutting will occur 22 . Figures 4 and 5 shows shape of the chips formed during dry turning of Al/SiCp and Al/SiCp-Gr composites using carbide, coated carbide and PCD tools at a cutting speed of 110 m/min a feed rate of 0.1 mm/rev and at a depth of cut of 0.3 mm.…”

“…Thus in machining of the composites while the matrix deforms plastically and the SiC particles may only deform elastically or break. The reinforcing particles both SiCp and Graphite act as chip breakers in turning of Metal Matrix composites [20][21][22] . Analysis of prior research shows that the effect of turning on surface roughness of hybrid metal matrix composites has not been adequately addressed.…”

This study presents an experimental investigation on surface roughness and chip formation in turning of Al 2219/15SiCp and Al 2219/15SiCp-3Gr (hybrid) composites. Experiments were conducted with different cutting conditions using carbide, coated carbide and polycrystalline diamond (PCD) tools. The results reveal that the surface roughness values are less for coated carbide tools compared to carbide and are minimum for PCD tools. The incorporation of graphite in Al 2219/15SiCp composite increases the surface roughness. This is due to smearing and removal of softer and amorphus graphite particles on the surface of the specimen, creates pits on the machined surface which increases the surface roughness values. The graphitic composite produced discontinuous chips leads to easy machining. PCD tool performs better than carbide and coated carbide tools.

“…Probability of particle fracture is much higher for larger particles comparing to that of smaller particles. Quan et al [15] noted large quantity of harmful dust after machining MMC with larger particle size but those disappeared during machining MMC with smaller particle size. This observation reveals two main facts: (i) this dust is due to fracture of particles in tool-chip and tool-workpiece interfaces; (ii) huge number of particles are accumulating at the tool-chip interface and those particles are fractured and debonded.…”

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.
