“…The Jatropha oil proved to be the best one for being used in the machining AA7050-T7451 [19]. The coconut oil is impressive in reducing surface roughness at higher values of feed and depth of cut while turning hardened AISI 52100 [20] and also showed an improved tool life for turning of AISI 304 [21].…”

Owing to the desirable properties of vegetable oils as cutting fluids, an attempt is made to explore the potentiality of plentifully available vegetable oils as a cutting fluid for turning AA 6061. Two nonedible vegetable oils, Jatropha and Pongamia, in their chemically modified (epoxidized) versions are used as straight cutting fluids. Cutting fluids are introduced to the machining zone with the aid of Minimal Quantity Lubrication (MQL) method. Taguchi's technique of orthogonal arrays is used to develop an effective design of experiments. The results obtained under epoxidized versions of Jatropha and Pongamia oils are compared with the results of mineral oil in terms of cutting forces and surface roughness. Experimental observations and statistical analysis show that, compared to mineral oil, the modified versions of vegetable oil-based cutting fluids are more effective in reducing the cutting forces and increasing surface finish. It is also observed that the modified Pongamia oil showed lesser flank wear compared to the other two tested oils.

“…In this case, a effective cooling method is needed to reduce the cutting temperature. However, the regular cooling method which often uses the regular coolant liquid with large rate of flow may cause the oxidization on the surface of the aluminum alloy and the contamination by the cutting oil which has a detrimental effect on the subsequent welding process of the parts [4]. The expensive special coolant is often applied when heavy machining aluminum alloy structures, which in turn greatly increases the machining cost [5].…”

“…These problems have a great influence on the efficiency, quality and cost when machining this kind of material. Heavy cutting method was generally used when machining aluminum structures so as to improve the efficiency [3], which causes a high level of cutting force and cutting temperature that leads to the generation of obvious build-up-edge or the melt of the aluminum alloy [3][4]. In this case, a effective cooling method is needed to reduce the cutting temperature.…”

In order to fill the mechanism of microstructure evolution and corrosion resistance of 7055 aluminum alloy in extreme environment, the 7055 aluminum alloy Which was subjected to T6I4 heat treatment was selected as the research object. High speed machining experiments were performed at low temperature (-60°C) and high temperature (350°C). The dislocation density, grain size, TEM microstructure and corrosion resistance of the cutting layer of 7055 aluminum alloy were investigated at low temperature (-60°C) and high temperature (350°C). The experimental results show that the dislocation density at low temperature is higher than that at high temperature under the same cutting speed and feed rate, and the grain size at low temperature is higher than that at high temperature too. In the low temperature environment, the continuous of the grain boundary is enhanced with the cutting speed increases, and the precipitation phase in the crystal is reduced and the precipitation phase on the grain boundary is obviously increased. Under the high temperature environment, with the increasing cutting speed, the degree of fibrosis of the grains is weakened and the dynamic recrystallization is obviously enhanced. Microstructures show significant dynamic recrystallization after high temperature cutting. And when the feed rate is 0.05 mm, the microstructure of 7055 aluminum alloy exists part of the sub-crystal; The larger the feed amount, the finer and longer the fibrous grains of the metallographic structure of cutting layer metal of 7055 aluminum alloy. There is a lot of dislocations in the cutting layer of 7055 aluminum alloy in low temperature environment. The higher the cutting speed, the smaller the dislocation density. No dislocations were found in the microstructure of the 7055 aluminum alloy cutting layer in the high temperature environment,and, the higher the cutting speed is, the less the number of precipitated phases is, and the GP region and η 'phase were transformed into η phase.
