“…Mostly cutting speed does not have an influence on cutting forces while machining of MMCs, according to Coelho [26]. During machining of various MMCs, BUEs have been noticed by many researchers at low cutting speeds [27,28,29].…”

“…Hung et al[50] had investigated the turning of MMC with CBN, PDC, WC, and DCC tools. Chen and T. Hoshi[27] observed that cutting speed and temperature did not have much impact on tool wear of WC tools.Coelho et al[26] had discussed the same experience for WC and PCD tools. This conclusion can probably wave out the fact that abrasion is the cause of tool wear while machining of SiC reinforced MMCs.…”

Intrinsically smart, metal matrix composites (MMCs) are lightweight and highperformance materials having ever expanding industrial applications. The structural and the functional properties of these materials can be altered as per the industrial demands.The process technologies indulged in fabrication and machining of these materials attract the researchers and industrial community. Hybrid Electric discharge machining is a promising and the most reliable non-conventional machining process for MMCs. It exhibits higher competence for machining complex shapes with greater accuracy. This paper presents an up-to-date review of progress and benefits of different routes for fabrication and machining of composites. It reports certain practical analysis and research findings including various issues on fabrication and machining of MMCs. It is concluded that polycrystalline tools and diamond coated tools are best suitable for various conventional machining operations. High speed, small depth of cut and low feed rate are a key to better finish. In addition, hybrid EDM has proved to be an active research area in critical as well as non-conventional machining since last few years. This paper incorporates year wise research work done in fabrication, conventional machining, nonconventional machining and hybrid machining of MMCs. Conclusions and future scope are addressed in the last section of the paper.

“…However, hard ceramic reinforcements of the PMMCs cause serious abrasive tool wear and then poor machinability during machining [2][3][4][5]. 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.…”

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.

“…However, a study of the machinability of the MMCs in the milling operations is very limited as regards the machining cutting parameters and tool wear to the work piece surface roughness and cutting force. In previous studies, machining of SiC reinforced aluminium composites in the milling operations was investigated and the flank wear rate on cutting tool with increasing cutting speed was increased (Coelho et al, 1993). In another work, machinability of particle and fibre reinforced MMCs materials in milling operation with polycrystalline diamond tools was conducted (Cronjager and Meister, 1992).…”

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
