“…They found a substantial improvement in the turning process performance characteristics in MQL condition due to the significant reduction of machining zone temperature when compared dry machining condition. Sivaiah and Chakradhar [9][10][11] performed turning experiments on 17-4 PH SS under MQL, wet and dry machining environments. They found a significant reduction in R a , T w under MQL environment over the wet and dry machining environments.…”

Built-up-edge formation is one of the problems in conventional (flood) machining of 15-5 precipitated hardened stainless steel (PH SS) which results in poor product quality. Further, concentration on stringent environmental conscious regulations has been increasing in metal cutting industries due to environmental pollution. The present work target is to address these problems using minimum quantity lubrication (MQL) machining technique. MQL machining technique is one of the promising techniques for the metal cutting industries because it satisfies the stringent environmental conscious regulations set for metal cutting industries in terms of usage and disposal of chemically contaminated emulsion based coolants. In the present work, studied the effect of MQL cooling, process parameters on turning performance characteristics and also established a relationship between the turning controllable process parameters and responses in the machining of 15-5 PH SS using response surface methodology (RSM) under MQL environment with tungsten carbide cutting insert. Spindle speed (v), feed rate (f), depth of cut (d) and MQL flow rate (Q) have been taken as MQL machining process parameters. Output turning performances considered were surface roughness (R a), tool flank wear (T w) and material removal rate respectively. Experiments were done based on the central composite design of RSM. From RSM analysis, it was noticed that developed mathematical models predicted the performance results close to the experimental results. Further, it was observed that surface roughness and tool wear reduced significantly with an increase in MQL flow rate respectively.

“…Furthermore, the reduction in cutting temperature was more obvious at a lower feed and lower cutting velocity. Sivaiah and Chakradhar compared cryogenic, MQL, wet, and dry machining conditions in turning 17-4 PH stainless steel and they found that cryogenic turning outperformed in terms of tool wear, surface finish, and chip morphology compared to other three conditions [41]. The improvement was mainly due to retainment of cutting tool edge under cryogenic condition.…”

Cryogenic machining is a relatively new technique in machining. This concept was applied on various machining processes such as turning, milling, drilling etc. Cryogenic turning technique is generally applied on three major groups of workpiece materials—superalloys, ferrous metals, and viscoelastic polymers/elastomers. The roles of cryogen in machining different materials are unique and are summarised in this review article. Finally, the challenges in using cryogenic machining in industries are also highlighted.

“…In order to increase the speed from 60 to 120 m min −1 and even beyond (industry goal is 100 m min −1 and above; Bermingham et al, 2011) the employment of coolant comes in. The use of a coolant is quite well known practice ranging from traditional high pressure coolant (HPC) (Sivaiah and Chakradhar, 2018;Sun et al, 2015) to minimum quantity lubrication (MQL) (Kaynak et al, 2014;Senevirathne and Punchihewa, 2017;Khatri and Jahan, 2018) and then with the introduction of cryogenic coolants (Aramcharoen, 2016;Bagherzadeh and Budak, 2018;Bermingham et al, 2011;Bordin et al, 2015;Zhao and Hong, 1992a;Lu et al, 2018;Hong et al, 1999) i.e. Liquid Nitrogen, Argon to name a few.…”

“…Liquid Nitrogen, Argon to name a few. The cost effects of coolant needs to be weighed against advantages as coolants accounts for almost 20 % of the total manufacturing cost (Shokrani et al, 2012;Sreejith and Ngoi, 2000). This important aspect will be taken up as future work by the authors.…”

Abstract. Productivity and economy are key elements of any sustainable manufacturing system. While productivity is associated to quantity and quality, economy focuses on energy efficient processes achieving an overall high output to input ratio. Machining of hard-to-cut materials has always posed a challenge due to increased tool wear and energy loss. Cryogenics have emerged as an effective means to improve sustainability in the recent past. In the present research the use of cooling conditions has been investigated as an input variable to analyze its effect on tool wear, specific cutting energy and surface roughness in combination with other input machining parameters of feed rate, cutting speed and depth of cut. Experimental design was based on Taguchi design of experiment. Analysis of Variance (ANOVA) was carried out to ascertain the contribution ratio of each input. Results showed the positive effect of coolant usage, particularly cryogenic, on process responses. Tool wear was improved by 33 % whereas specific cutting energy and surface roughness were improved by 10 % and 9 % respectively by adapting the optimum machining conditions.
