“…Among the different forming processes used in the manufacture of these parts, machining is one of the most common (mostly turning, drilling, and milling operations) [8,9]. Although aluminum alloys have, in general, good machinability [10], when they are hybridized with CFRP, several problems arise, which remain mostly unresolved [11,12].…”

Aluminum alloys are widely used in the manufacturing of structural parts for aircraft, frequently in combination with other materials such as CFRP (Carbon Fiber Reinforced Polymer), to form FML (Fiber Metal Laminates) structures (CFRP/Al). The dry machining of these structures presents several problems, some of which are related to chip evacuation, either when machining aluminum alloys as an isotropic material, or during hybridization with composites. In this work, a study of the way in which cutting parameters influence the chip morphology in the dry machining of UNS A97075-T6 (Al-Zn) and UNS A92024-T3 (Al-Cu) alloys, is performed. Thus, different geometric parameters of the chip morphology have been obtained, and their evolution with feed has been analysed. Finally, the different relationships which occur between these geometric parameters and feed, have been obtained. These relationships allow a prediction of the evolution of some of the geometric parameters of the chip, as a function of feed.

“…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.

“…Taguchi L 27 (3 13 ) orthogonal array is used for the experimental design and the significance of process parameters is evaluated by ANOVA. Nouari et al [8] analyzed the influence of input process parameters in drilling aluminium alloy on tool life and hole quality. They have recommended using reduced web thickness, increasing the helix and point angle to optimal drill geometry.…”

Carbon Fiber Reinforced Polymer (CFRP) is the most preferred composite material due to its high strength, high modulus, corrosion resistance and rigidity and which has wide applications in aerospace engineering, automobile sector, sports instrumentation, light trucks, airframes. This paper is an attempt to carry out drilling experiments as per Taguchi's L 27 (3 13 ) orthogonal array on CFRP under dry condition with three different drill bit type (HSS, TiAlN and TiN). In this research work Response Surface Analysis (RSA) is used to correlate the effect of process parameters (cutting speed and feed rate) on thrust force, torque, vibration and surface roughness. This paper also focuses on determining the optimum combination of input process parameter and the drill bit type that produces quality holes in CFRP composite laminate using Multi-objective Taguchi technique and TOPSIS. The percentage of contribution, influence of process parameters and adequacy of the second order regression model is carried out by analysis of variance (ANOVA). The results of experimental investigation demonstrates that feed rate is the pre-dominate factor which affects the response variables.
