“…This is because poor surface finish can be sometimes an indication of BUE formation. Similar works on machinability of MMC's with large volume fraction of reinforcement particle have shown poor machined surfaces when coated tools were used [3,4,9]. Previous works [6,8] reported that the size of reinforcement particles had much stronger effect on tool lives than that of population of reinforcement particles.…”

“…Previous works [6,8] reported that the size of reinforcement particles had much stronger effect on tool lives than that of population of reinforcement particles. Looney et al [3] found coated tools performed best in terms of flank wear but gave the poorest surface finish when machining composites of SiC as reinforcement particles. This is in consistent with the present study but of alumina as reinforcement particles was used instead of SiC.…”

“…The main problem when machining MMC is the extensive tools wear caused by the very hard and abrasive reinforcements. Several studies have been performed in order to examine the efficiency of different cutting materials, such as cemented carbide and diamond, in turning, milling, drilling, reaming, and threading of MMC materials [3,4]. The test results showed the influences of the reinforcement material on tool wear and the surface integrity of MMC.…”

A wide range of particulate metal matrix composites (PMMCs) of alumina and aluminum powders was formed using powder metallurgy techniques followed by extrusions at various extrusion ratios. The machining characteristics of the extruded PMMC were investigated. Results showed significant effects of weight fractions of reinforcement and extrusion ratios on tool wear and surface integrity of machined surface. The wear rate of cutting tool decreased rapidly with increasing the cutting parameters: cutting speed, feed, and depth of cut, however cutting speed is shown to be more effective. Sudden breakage of tool inserts occurred when the experiment started at high cutting speed. Wear rate has also decreased by decreasing volume fraction of reinforcement particles. Coating carbide tools have significantly improved the tool life. Coated tools showed 5% decrease in flank wear size compared to uncoated tools. This was valid within tested range of weight fractions and extrusion ratios. The surface finish of machined surfaces deteriorated when coated carbide tools were used. However, surface finish did not change significantly when volume fractions or extrusion ratios were altered.

“…But Al/SiC-MMC machining is one of the major problems which stop it from being used in widespread engineering applications [2]. Some early conventional turning tests on Al/SiC-MMCs [3,4,5], showed that tool wear is excessive and surface finish is very poor when carbide tip tools are used for machining. During machining of Al/SiC-MMCs, the use of coolant increases tool wear and also produces a very poor surface finish [6].…”

This paper presents an experimental investigation of the influence of cutting conditions on surface finish during turning of Al/SiC-MMC. In this study, the Taguchi method, a powerful tool for experiment design,is used to optimise cutting parameters for effective turning of Al/SiC-MMC using a fixed rhombic tooling system. An orthogonal L 27 (3 13 ) array is used for 3 3 factorial design and analysis of variance (ANOVA) is employed to investigate the influence of cutting speed, feed and depth of cut on the surface roughness height R a and R t respectively. The influence of the interaction of cutting speed/feed on the surface roughness height R a and R t and the effect of cutting speed on cutting speed/ feed two factor cell total interaction for surface roughness height R a and R t are analysed through various graphical representations. Taking significant cutting parameters into consideration and using multiple linearregression, mathematical models relating to surface roughness height R a and R t are established to investigate the influence of cutting parameters during turning of Al/ SiC-MMC. Confirmation test results established the fact that the mathematical models are appropriate for effectively representing machining performance criteria, e.g. surface roughness heights during turning of Al/SiC-MMC.

“…Many researchers have investigated the tool wear and surface integrity during machining of MMCs, they found that the tool wear is excessive and surface finish is very poor when carbide tools are used for the machining of Al/SiC-MMC alloys (Looney et al, 1992;Weiner and Konig, 1993). It was also found that in most cases, the tool wear was due to abrasion by the hard reinforcement particles in the matrix material (El-Gallab and Sklad, 1998a;Hung and Zhong, 1996;Davim, 2012;Luliano et al, 1998).…”

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.
