“…The BUE formation acts as a protective cover on the nose area and will prolong the tool life of uncoated carbide tools in the machining of AlSi/AlN MMC. This phenomenon also happens during machining of other MMC (Karakaş et al, 2006;Muthukrishnan et al, 2007). Fig.…”

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.

“…In these studies, optimum cutting parameters, tool flank wear, mean cutting force and surface roughness were investigated for coated and uncoated tools and different cutting parameters. The flank wear was increased of all investigated tools with increasing cutting speeds whereas, flank wear of all investigated tools decreased with increasing feed rate (Karakas et al, 2006;Ubeyli et al, 2007;. On the other hand, the surface roughness decreased drastically for all tools with increasing cutting speed (Ubeyli et al, 2008).…”

In this experimental study, composite samples containing silicon are produced with powder metallurgy technique by sintering under argon atmosphere. The effect of cutting speeds, feed rates and different cutting tool types on cutting forces and surface roughness are investigated in the face milling operation of silicon carbide particle reinforced aluminium metal matrix composites. Machining operations are conducted using coated and uncoated tools. Main cutting force (F x ) and surface roughness (Ra) are measured for at four different cutting speeds (300, 350, 400 and 450 m/min) and three different feed rates (0.1, 0.15, 0.20 mm/tooth) and two depth of cut (0.5, 1 mm). As a result of experimental evaluation for coated and uncoated tools, main cutting force increased with increasing feed rate and depth of cut whereas, it is decreased significantly by higher cutting speed. On the other hand, Al-SiC produces the worst surface finish with increasing feed rate and depth of cut in the uncoated tools whereas, the surface roughness in the coated tools are decreased under the same cutting conditions. The best surface roughness is obtained with increasing cutting speed for both uncoated and coated tools.Key words: Metal matrix composite, face milling, machining, cutting forces, surface roughness. INTRODUCIONRecently, the reinforced metal matrix composites (MMCs) are widely used in aerospace, automotive, electronic and medical industries. Silicon carbide (SiC) and alumina (Al 2 O 3 ) as the matrix phase in the production of metal matrix composites are used the popular reinforcement in the literature (Rohatgi, 1990;Monaghan, 1994;El-Gallab and Sklad, 1998;Koczak et al., 1993). Net shaping and good surface finish of particulate metal matrix composites (PMMCs) are very important for machining operations. However, PMMCs show poor machinability because of the fact that their reinforcements cause serious abrasive tool wear and the worst surface finish during machining

“…In another study, effect of cutting speed on tool performance (uncoated cementide carbide, multiple coated (TiCN + Al 2 O 3 + TiN) cementide carbide) in milling of the same material was examined using a feed rate of 0.15 mm/z [28]. In this study, the wear behavior of three different types of tool in milling of Al-4%Cu/B 4 C p composites at a feed rate of 0.25 mm/z was investigated to determine the effect of feed rate on the tool performance in milling of these composites by comparing with these two recent studies [27,28]. Moreover, to make a full comparison, composites were also tested at a feed rate of 0.15 mm/z by using the double coated (TiN + TiAlN) cementide carbide tool.…”

“…Studies have been focused on the wear behavior of different types of tools in turning of MMCs [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], whereas the studies on the tool wear behavior in milling of these materials are very scarce [22][23][24][25][26]. Recently, performance of different type of tools (uncoated cementide carbide, triple coated (TiCN + Al 2 O 3 + TiN) cementide carbide, double coated (TiN + TiAlN) cementide carbide) used in milling of B 4 C particulate reinforced aluminum matrix composite at a feed rate of 0.20 mm/z [27] was investigated. In another study, effect of cutting speed on tool performance (uncoated cementide carbide, multiple coated (TiCN + Al 2 O 3 + TiN) cementide carbide) in milling of the same material was examined using a feed rate of 0.15 mm/z [28].…”

The effect of feed rate on tool wear in milling of B 4 C p reinforced aluminum metal matrix composites (MMCs), produced by liquid phase sintering method, was investigated. Milling experiments on these composites were conducted with three different types of cementide carbide tools (uncoated, double coated (TiN + TiAlN) and triple coated (TiCN + Al 2 O 3 + TiN)) for three different feed rates of 0.15 mm/z, 0.20 mm/z, and 0.25 mm/z. After milling experiments, an optical microscope was used to measure the magnitude of flank wear on the tools. Flank wear limit value, V B = 0 3 mm was selected as a reference value for comparison of these tools. On the other hand, tool wear mechanisms were examined with the help of a scanning electron microscope (SEM). Experimental results indicated that higher feed rates led to lower tool wear for all type of tools and coated tools exhibited better performance than uncoated tool with respect to the flank wear.
