Effect of extrusion temperature on the surface roughness of solid state recycled aluminum alloy 6061 chips during turning operation

Abstract: Nowadays solid state recycling of aluminum chips provides a competitive market for the aluminum foundry. Chip recycling requires an efficient pretreatment system in terms of optimizing consolidating technique to achieve a high metal recovery with rapid return of investment and hence drive down fixed cost and increase productivity without compromising on metal quality. Solid state recycling through hot extrusion is a promising technique to recycle machining chips without re-melting. In this article, aluminum ch… Show more

“…Turning now to the papers that have described the establishment of optimum surface roughness in turning [40][41][42][43][44][45][46], Zuperl and Cus [40] proposed a neural network-based approach to complex optimization of cutting parameters, considering technological, economic, and organizational limitations. Gupta et al [41] focused on process parameter optimization in turning operations: surface roughness, flank tool wear, and required power using an ANN integrated with a genetic algorithm (GA).…”

“…Abbas et al [45] investigated surface roughness in the turning of solid-state recycled aluminum alloy 6061 chips. Ragab et al [46] investigated the effect of extrusion temperature and turning parameters on the surface roughness of aluminum alloys 6061. However, studies [40][41][42][43][44][45] provided only a one-sided interpretation of the problem of estimating the optimum cutting conditions by taking surface roughness into consideration, but not its correlation with the unit volume machining time, T m , and the cost of machining, C, which is unacceptable in the machining of materials as expensive as an aluminum alloy 6061.…”

“…Figure 3 clearly shows that surface roughness and machining time vary inversely (Qehaja et al, 2015, Bindhushree et al, 2021, Ragab et al 2017. Machining time varies inversely with feed rate and cutting speed.…”

“…The optimum machining conditions were v = 116 m/min, s = 0.11 mm/rev, and a = 0.33 mm when the extrusion temperature was 500 ⁰C. The sample produced under these conditions had a surface roughness Ra below the industrially accepted value [10] . Moreover, Krolo et al studied the effect of direct extrusion temperature (400, 450, and 500⁰C), ECAP temperature (20, 160, and 300 ⁰C), and ECAP pass number (1, 3, and 4) on microhardness and electrical conductivity of solid-state recycled AW6082 chips.…”
