“…Cooling liquid wasn't used in order to decrease possible heat shock in cutting tool during the experiment [11]. The experiments were done on the radial drill bench with a brand mane of Stanke Import with a progress interval of 0.056 mm/rev and 2, 5 mm/rev working between 20 and 2000 rpm.…”

“…Machining of aluminum matrix composites are very difficult by conventional machining process, namely turning, milling, drilling and sawing etc. due to their extreme abrasive properties [3][4][5]. Che Chung Wang [6] investigated optimization of the blind-hole drilling of Al 2 O 3 /6061Al composites, using rotary electro discharging machining, by using Taguchi method.…”

“…Li and Seah (2001) found that the abrasive wear of the tool was accelerated when the percentage of the reinforcement in the MMC exceeded a critical value, which varies with the density and size of the reinforcement particles. Moreover, most of the studies about the machinability of MMC's were carried out using materials with ceramic particles with a size of 25 microns or larger, resulting in bad performance of the hard metal (WC) tools, (Durante et al, 1997;Muthukrishnan et al, 2008a;Muthukrishnan et al, 2008b).…”

“…The Poly-Crystalline Diamond (PCD) tools provide a suitable tool life for high speed machining of MMC materials (Durante et al, 1997;Muthukrishnan et al, 2008a;Muthukrishnan et al, 2008b), thanks to their high hardness compared to conventional reinforcement materials like alumina (Al 2 O 3 ) and silicon carbide (SiC). El-Gallab and Sklad (1998a) found that the Built Up Edge (BUE) formed during machining could protect the tool from abrasive wear.…”

“…The influence of the PCD characteristics is analyzed. Despite the WC is not the most suitable material for the machining of this kind of materials (Davim, 2012), AMC225XE is normally produced by powder metallurgy, leading that the matrix can be reinforced with ultrafine SIC particles (2-3 microns), slightly lower than others MMCs reported in literature (Durante et al, 1997;Muthukrishnan et al, 2008b). Because a smaller particle size means less inertia force of the ceramic grains, it is expected that the abrasive wear will be reduced.…”

SUMMARY:The aim of this work is the study of the machinability of aluminium-silicon carbide Metal Matrix Composites (MMC) in turning operations. The cutting tools used were hard metal (WC) with and without coating, different grades and geometries of Poly-Crystalline Diamond (PCD) and Mono-Crystalline Diamond (MCD). The work piece material was AMC225xe, composed of aluminium-copper alloy AA 2124 and 25% wt of SiC, being the size of the SiC particles around 3 μm. Experiments were conducted at various cutting speeds and cutting parameters in facing finishing operations, measuring the surface roughness, cutting forces and tool wear. The worn surface of the cutting tool was examined by Scanning Electron Microscope (SEM). It was observed that the Built Up Edge (BUE) and stuck material is higher in the MCD tools than in the PCD tools. The BUE acts as a protective layer against abrasive wear of the tool. RESUMEN: Maquinabilidad de composites de matriz metálica Al-SiC usando herramientas de WC, PCD y MCD.El objetivo de este trabajo es el estudio de la maquinabilidad del material compuesto de matriz metálica aluminio-carburo de silicio en operaciones de torneado. Las herramientas de corte utilizadas han sido de metal duro con y sin recubrimiento, diferentes grados de diamante policristalino (PCD) y diamante monocristalino (MCD). El material mecanizado ha sido AMC225xe, compuesto de la aleación de aluminio AA 2124 con un 25% en peso de partículas de SiC con un tamaño medio de 3 μm. Los experimentos se han realizado con diferentes velocidades de corte en una operación de refrentado, midiendo la rugosidad superficial, las fuerzas y el desgaste de la herramienta. La superficie desgastada de la herramienta ha sido examinada en el microscopio electrónico (SEM). Se ha observado que el filo recrecido y el material adherido son mayores en el caso de las herramientas de MCD que en las de PCD. El filo recrecido actúa como una capa protectora contra la abrasión.
