“…Figure 2 shows that the microhardness of Al-Mg-Si layer increased up to 113 HV by aging at 175 • C. The microhardness of as-rolled Al-Mg-Si aged at 175 • C for 6 h was similar to that of Cu layer. The increase of hardness with aging at 175 • C is mainly due to the precipitation in Al-Mg--Si alloy [16][17][18]. Figure 3 shows electrical conductivity of as-rolled and aged Cu/Al-Mg-Si/Cu clad composite.…”

Tri-layered Cu/Al-Mg-Si/Cu clad composite was cold roll-bonded, and its mechanical/electrical properties were studied. In the roll-bonded and aged Cu/Al-Mg-Si/Cu clad composite, neither interfacial reaction layer nor interface defects were observed. The strength as high as 415 MPa with the conductivity of 82 % IACS was attained in 3-ply lightweight Cu/Al-Mg-Si/Cu clad composite. The ductility and conductivity of clad composite are increased appreciably with heat treatment at 175 • C. After mechanical testing, the interface crack propagation and fracture in the well-bonded interface between metallic Cu and Al occurred in softer Al matrix. The increase of detached Al lumps onto the separated Cu side in clad composite heat-treated at 175 • C strongly supports that the interface bonding can be enhanced during aging of Al-Mg-Si alloy layer in Cu/Al-Mg-Si/Cu clad composite. The increased ductility in the aged Cu/Al-Mg-Si/Cu clad composite can be attributed to the enhanced interface bonding and precipitation in Al-Mg-Si layers.

“…The cutting tool insert used was a carbide (DNGP-432 KC5410, Kennametal, Latrobe, PA, USA) with Titanium diboride (TiB 2 ) coating, while the coolant was Mecagreen 550 lubricant coolant mixed with 15% water at 3 and 1.75 mL/min flow rate. The effect of MQL in the machining of a 6082 aluminum alloy was studied by Yigit [ 14 ]. The diamond-coated carbide was used as insert, while the lubricant was commercial oil Rocol A208A plus, applied at 50 mL/h and 100 mL/h.…”

Precise, economical and sustainable cutting operations are highly desirable in the advanced manufacturing environment. For this aim, the present study investigated the influence of cutting parameters (i.e., the cutting speed (c), feed rate (f), depth of cut (d) and positive rake angle (p)) and sustainable cutting conditions (dry and minimum quantity lubricant (MQL)) on cutting forces (i.e., feed force (Ff), tangential forces (Ft), radial force (Fr) and resultant cutting forces (Fc) and shape deviations (i.e., circularity and cylindricity) of a 6026-T9 aluminum alloy. The type of lubricant and insert used are virgin olive oil and uncoated tungsten carbide tool. Turning experiments were performed on a TAKISAWA TC-1 CNC lathe machine and cutting forces were measured with the help of a Kistler 9257B dynamometer. Shape deviations were evaluated by means of a Tesa Micro-Hite 3D DCC 474 coordinate measuring machine (CMM). Experimental runs were planned based on Taguchi mixture orthogonal array design L16. Analysis of variance (ANOVA) was performed to study the statistical significance of cutting parameters. Taguchi based signal to noise (S/N) ratios are applied for optimization of single response, while for optimization of multiple responses Taguchi based signal to noise (S/N) ratios coupled with multi-objective optimization on the basis of ratio analysis (MOORA) and criteria importance through inter-criteria correlation (CRITIC) are employed. ANOVA results revealed that feed rate, followed by a depth of cut, are the most influencing and contributing factors for all components of cutting forces (Ff, Ft, Fr, and Fc) and shape deviations (circularity and cylindricity). The optimized cutting parameters obtained for multi responses are c = 600 m/min, f = 0.1 mm/rev, d = 1 mm and p = 25°, while for cutting conditions, MQL is optimal.

Cutting fluids play an important role in machining operations helping reduce friction, workpiece heating, tool wear and also with chips detachment and evacuation. The usage of cutting fluids also have a number of drawbacks that are related with the environmental threats and costs. Dry matching and MQL-minimum quantity of liquid seem to be promising solutions for these problems. But these solutions are not feasible under all machining applications. The present paper purpose is to investigate the effect of cutting and cooling conditions over surface quality in aluminium alloy 6082-T6 turning operations.
