Based on the necessity of a solid study on the orientation of liquid nitrogen jets in turning, this study investigates the specific cutting energy, surface roughness, chip morphology, chip–tool interface temperature, tool life, and wear of coated carbide tool under the single and duplex jets liquid nitrogen for congenial turning of a hard-to-cut superalloy (Ti-6Al-4V). The single jet was aimed at rake face, whereas the duplex jets were impinged at rake and flank surfaces, simultaneously. Results showed that the later coolant employment method ensured the most favorable machining characteristics, which can be accredited to the extreme cooling by liquid nitrogen jets, in terms of reduced specific cutting energy, temperature, roughness, and admittedly, an increased life of tools. The duplex liquid nitrogen jets prolonged tool life by 60% and 30% compared to dry and single jet assistance, respectively. However, no visible difference in chip formation has been noticed. In recapitulation, the duplex liquid nitrogen jets are established as sustainability promoter as—tool life is increased thus tool cost is reduced, required energy is lessened, temperature is pacified, surface quality is improved, and above all, favorable machinability of Ti-6Al-4V superalloy is attained.

“…4), and the factor levels were accordingly A1, B1, and C2 for minimal residual stress in the cutting direction. The temperature rose with cutting speed and feed rate.It is because that an rising cutting speed can lead to a moderate reduction in the cutting force and feed force but cutting force and feed force soared as feed rate increased in this work [9]- [11].…”

Despite numerous studies focused on the residual stress induced from various machining parameters, the optimization of process parameters for the minimum residual stress machining of nodular cast iron has not been found in the current research. This paper aimed to optimize the milling parameters for low residual stress when nodular cast iron was machined. The experiments were performed with three control factors: cutting speed, feed rate and depth of cut in an L16(4 3 ) orthogonal array. The X-ray diffraction (XRD) technique was used to measure the residual stresses in both directions. The results indicate that the cutting speed and feed rate but depth of cut play crucial roles in minimizing the residual stress. He is the deputy director of the Department of Mechanical Design.His research interests include residual stress, structural dynamics, and mechanical design. He has presided over a variety of national program on key basic research of project (973 projects) and national high-tech R&D program of China ( 863 programs), and published 48 papers and obtained 10 patents.

Abstract-Turning is one of the most popular convectional machining processes to remove the extra material from the rotating surfaces. In this process, a wedge shaped cutting tool penetrated toward the workpiece and removed the extra material in the form of chips. Almost all known materials can be machined by this process in different forms like external turning, internal turning, plain/cylindrical turning, step turning, taper turning, face turning etc. with selection of appropriate cutting tool for particular material. The aim of the present study is to summarize a report on the turning process including present and past research works. This paper present a brief overview on turning operation considering the different aspects and focus the future scopes of works in the same area, which is beneficial for the researches who work in the same field.
