“…Thus, the best alternate conditions chosen were cutting speed of 150 m/min, feed rate of 0.15 mm/rev and depth of cut of 0.50 mm under MQL 50 ml/h for productivity purpose. This condition is parallel with the literature as stated by Yildirim et al [20] that the flow rate of 50 ml/h was effective in which to form the film layer to extend tool life with reducing of the friction at the cutting tool and workpiece interface.…”

Turning operations are a versatile secondary metal cutting process. In metal cutting industry, manufacturing processes are designed to attain minimum manufacturing cost, best quality and improved cutting tool's performance. Nonetheless, the deterioration of cutting tools, occupational diseases amongst the workers and environmental aspects are increasingly becoming a major issue. Therefore, one alternative to reduce the impact of metal cutting activity in term of cutting tool, the health and environment is Portable MQL Applicator. The portable MQL applicator is an equipment that equipped with pneumatic system to deliver a small amount of fluid in the form of aerosol into the cutting zone. The effect of the portable MQL applicator was investigated and compared with the results from dry machining in terms of tool life and material removal rate in turning of Inconel 718 using carbide tool. The results showed that the applications of the portable MQL applicator have successfully resulted in better tool life and improved material removal rate.

“…Similarly, Junior and Diniz have studied the machinability indexes in milling process while machining of 15-5 PH SS material [2]. Yıldırım et al [20] performed milling experiments on Waspaloy by considering cutting oil type, fluid flow rate, milling method, spray distance and nozzle type as process parameters whereas tool life and cutting forces are taken as responses. In a while, modelling and optimization studies have been carried out and validated through confirmation tests respectively.…”

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.

“…The study also pointed out that heat generation; torque and cutting force are lower for MQL using palm oil than MQL using synthetic ester because of higher viscosity of palm oil (40mm2/s). Yildrim et al [61] compared the efficiency of vegetable oil over synthetic, mineral and mineral-synthetic oils with different flow rates in milling using Taguchi approach.…”

Various types cooling/lubrication techniques are used in machining processes for enhancing machining performances. Conventional way of cooling/lubrication requires higher coolant cost, waste and disposal cost. Not only has that it had many negative impacts on environment and operators health. For attaining highest efficiency of cutting fluids with minimum quantity, different sustainable strategies are tried to develop. In recent decades researchers are worked out on different cooling/lubrication strategies alternative to conventional cooling. This paper represents a comprehensive review of all presently practiced cooling/lubrication strategies and their effects on different aspects such as surface quality of machined component, tool wear, tool life, cutting temperature, cutting forces etc. through analyzing selected papers. The influence of different cutting fluids such as solid lubricants, nanofluids, ionic liquids etc. with their positive and negative impacts is also discussed. The research gaps are also identified for further research works. From review it is clear that the machining performance is highly affected by cooling techniques and coolant types. Selection of proper cooling technique with suitable cutting fluids depends on work material, tool material and cutting variables.
