Zirconia (ZrO 2) dispersed aluminum alloy metal matrix composites produced by stir casting techniques. Using stir casting techniques, aluminium based composites with varying amounts of 3%, 6%, 9%, and 12% of zirconia by weight are fabricated. The prepared samples were subjected to physical, mechanical,tribiology and microstructure investigation. The extraordinary performance of Aluminium MMCs was the low density that obtained after alloying. Hardness and ductility were also increased when increase in Zirconia particle. Ultimate tensile strength, compressive strength and impact toughness were slightly increasing with the addition of zirconia particle. Microstructural characteristics shows that a homogeneous distribution of particles with reinforcement in casted composite. The investigations of the metallurgical characterization were carried using optical, scanning electron microscope, X-ray diffraction and Energy Dispersive Spectrometry (EDS) test to understand the metallurgical properties.

“…1 and 2. From the results it is inferred that tool wear is influenced by speed and feed rate than other machining parameters [6,15].It clear that as speed increases, the flank wear increases, it is because, the increase in cutting speed increases the impact load on the work material by the insert due to the increased kinetic energy which cause a steady state increase in wear with speed assisted by the increased temperature at the interface. Similarly, as the feed increases flank wear increases owing to increase in force and work done in turn causes increase in heat generation and thermal load per cutting edge…”

“…Saeed chavosi [5] has investigated the effects of feed, depth of cut, and cutting speed on flank wear of Tungsten carbide and PCD inserts in CNC turning of 7075 Al Alloy with 10 % wt SiC Composites. Karthikeyan et al [6] has optimized the milling characteristics (Flank wear, Specific energy, and surface roughness) of Al-SiC particulate composites using goal programming technique and examined that volume fraction of SiC particles present in the aluminum alloy matrix has a significant effect on the milling characteristics increasing tool wear and specific energy and decreasing surface roughness. El-Gallab and Sklad [7] studied the surface integrity of Al/SiC particulate MMCs and concluded that surface roughness and flank wear increases with increase in the feed rate and cutting speed.…”

The research reported herein is to model the tool wear during face milling of Hybrid composites using response surface methodologies (RSM) and artificial neural network (ANN). Aiming to achieve this goal, several milling experiments were carried out with polycrystalline diamond (PCD) inserts at different machining parameters namely cutting speed, feed, depth of cut, and weight fraction of Al 2 O 3 . Materials used for the present investigation are Al 6061-aluminum alloy reinforced with alumina (Al 2 O 3 ) of size 45 microns and graphite (Gr) of an average size 60 μ, which are produced by stir casting route. Central composite face centered second order RSM was employed to create a mathematical model and the adequacy of the model was verified using analysis of variance. Comparison has been made between prediction capabilities of model based on RSM and ANN. The comparison clearly indicates that the models provide accurate prediction of tool wear in which ANN perform better than RSM.

“…It has been suggested that built-up edge occurs ideally at low cutting speeds [113]. Many studies suggest that the controlled formation of a built-up edge will result in an extension of the useful tool life during machining by protecting the tool from abrasive wear [41,[114][115][116]. It is suggested that the built-up edge protects the tool from the abrasive particle wear caused by the dispersed phase, acting as a sacrificial coating that is constantly replenished as the metal matrix is machined [85] [42].…”

Metal Matrix Composites (MMC) is a material which has been widely used in the aerospace and automobile industries since the 1980s, and has been classified as a hard to machine material. During the intervening years only a limited amount of research has been conducted into the cutting action of MMCs. As with traditional materials it is important to understand the wear mechanisms that contribute to tool wear reducing tool life. This review has been carried out to establish the optimum machining parameters vital to maximizing tool life whilst producing parts at the desired quantity and quality. The objective of this research is to evaluate the effectiveness of the machining parameters for these hard to machine material MMC.
