Abstract This paper presents research into the creation of refill friction stir spot welding (RFSSW) single-lap joints 6082-T6 aluminum alloy and roll-bonded AlCu bimetallic sheet. The latter sheet comprises EN AW-1050A electrolytic copper M1E in Z6 temper condition (after rolling) with a 1:1 ratio Cu:Al layers. parameters involved variable plunge depth time. mechanical properties were determin...

A 30-ton industrial bridge crane located at an aluminum sheet manufacturer has been equipped with a crane manipulation system enabling swing-free motion, disturbance rejection, and precise positioning. Previous investigations of anti-sway, positioning, and crane control have yielded important contributions in these areas. These advancements are combined into the unified crane manipulation syste...

The casting and hot rolling process is a most important and widely used industrial route to produce aluminum alloy sheet[I]. Because rolling is such a high volume process and the capital expenditure in plants and fabrication facilities is so large, even small cost savings or increases in efficiency can result in a very large total money savings[2, 3]. To remove the very costly and time-consumin...

A method of measuring biaxial stress-strain curves for sheet metal samples subjected to large plastic strains is described for one example aluminum alloy (AA 5754-O). The method uses a portable X-ray diffraction (XRD) system to measure in situ stresses during tensile deformations. Calibration of X-ray elastic constants and the effects of texture and intergranular stresses are discussed. Uniaxia...

One of the biggest challenges in Aviation industries is milling part features from prismatic blocks to part features with wall and floor thicknesses very similar to sheet metal assemblies. Much research has gone and is still going into machining processes of thin walled components and near net machining. This paper presents an overview in understanding the importance, criticalities and challeng...

because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...
