MQL has been successfully applied in various machining operations such as turning (Dhar et al, 2006a), drilling (Kelly and Cotterell, 2002), milling (Kishawy et al, 2005) and grinding (Sadeghi et al, 2009). Applications of MQL has resulted in better tool life, improved surface finish, better chip forms and reduced cutting forces (Varadarajan et al, 2002;Khan et al, 2009).…”

“…Increasing the cutting speed (it promotes sufficient softening of the alloy and prevents sticking in the cutting region), the rake angle, and the hardness up to a given value, as well as adequate lubrication, tends to reduce the cutting power. Oil-jet cooling or even the presence of free-cutting elements such as Pb (lead), Bi (bismuth), In (indium), or Sn (tin) in proportions of 0.10 to 1.0 % wt., combined with adequate cutting speeds in aluminum alloy drilling, can result in a significant reduction of the power since they promote lower adhesiveness and facilitate chip removal [24].…”

“…Temperature generated when machining of aluminum lem in the machining of aluminum alloys, because their low melting point is not able to alter the mechanical properties of cutting tools in other words, it is not able to cause high tool wear rates, although tool life is still controlled by the cutting temperature [24,25]. However, an increase in cutting temperature to a given level may generate microstructural alteration, residual stresses in the surface layer, tolerance errors, and distortions and accelerate tool wear and sticking of the work material onto tool edges.…”

The use of aluminum alloys in manufacturing industry has increased significantly in recent years. This is because primarily to their ability to combine lightness and strength in a single material. Concomitant to this growth, the machining of aluminum alloys has enormously increased in volumetric proportionsso that the chip volume represents up to 80 % of the original volume of the machined material in certain segments of the industry, like aerospace. In this context, knowledge of the characteristics of machinability of aluminum alloys is essential to provide industry and researchers with information that allows them to make the right decisions when they come to machining this fantastic material. The purpose of this review is to compile relevant information about the characteristics of machinability of aluminum alloys into a single document.

“…Aluminum is commonly machined with high speed steel, diamond and carbide tooling. However, silicon nitride-based ceramic tools are generally not used in aluminum because of the high solubility of silicon in aluminum [8]. Cutting forces are generally low and, because aluminum is a good conductor of heat, and since most aluminum alloys melt at temperatures between 500˚C and 600˚C, cutting temperatures and tool wear rates are also low [7,8].…”

Cutting forces are generally low and, because aluminum is a good conductor of heat, and since most aluminum alloys melt at temperatures between 500˚C and 600˚C, cutting temperatures and tool wear rates are also low [7,8]. When cut under proper conditions with sharp tools, aluminum alloys acquire fine finishes through turning, drilling and milling, minimizing the necessity for grinding and polishing operations.…”

In recent years, aluminum-matrix composites (AMCs) have been widely used to replace cast iron in aerospace and automotive industries. Machining of these composite materials requires better understanding of cutting processes regarding accuracy and efficiency. This study addresses the modeling of the machinability of self-lubricated aluminum /alumina/graphite hybrid composites synthesized by the powder metallurgy method. In this study, multiple regression analysis (MRA) and artificial neural networks (ANN) were used to investigate the influence of some parameters on the thrust force and torque in the drilling processes of self-lubricated hybrid composite materials. The models were identified by using cutting speed, feed, and volume fraction of the reinforcement particles as input data and the thrust force and torque as the output data. A comparison between two prediction methods was developed to compare the prediction accuracy. ANNs showed better predictability results compared to MRA due to the nonlinearity nature of ANNs. The statistical analysis accompanied with artificial neural network results showed that Al 2 O 3 , Gr and cutting feed (f) were the most significant parameters on the drilling process, while spindle speed seemed insignificant. Since the spindle speed was insignificant, it directed us to set it either at the highest spindle speed to obtain high material removal rate or at the lowest spindle speed to prolong the tool life depending on the need for the application.
