“…Chip reduction coefficient (ζ) is a ratio of the chip thickness before and after machining, which indicates the performance measure. In fact, ζ gives a qualitative indication of the power and specific energy utilised in the cutting process [36,[48][49]. The mean CRC for the nine runs was found to be around 1.655 with a standard deviation of 0.245 ( Figure 14) which shows the efficient machining under ionic fluid condition.…”

The current research presents an overall performance-based analysis of Trihexyltetradecylphosphonium Chloride [[CH3(CH2)5]P(Cl)(CH2)13CH3] ionic fluid mixed with organic coconut oil (OCO) during turning of hardened D2 steel. The application of cutting fluid on the cutting interface was performed through Minimum Quantity Lubrication (MQL) approach keeping an eye on the detrimental consequences of conventional flood cooling. PVD coated (TiN/TiCN/TiN) cermet tool was employed in the current experimental work. Taguchi’s L9 orthogonal array and TOPSIS are executed to analysis the influences, significance and optimum parameter settings for predefined process parameters. The prime objective of the current work is to analyze the influence of OCO based Trihexyltetradecylphosphonium Chloride ionic fluid on flank wear, surface roughness, material removal rate, and chip morphology. Better quality of finish (Ra = 0.2 to 1.82 µm) was found with 1% weight fraction but it is not sufficient to control the wear growth. Abrasion, chipping, groove wear, and catastrophic tool tip breakage are recognized as foremost tool failure mechanisms. The significance of responses have been studied with the help of probability plots, main effect plots, contour plots, and surface plots and the correlation between the input and output parameters have been analyzed using regression model. Feed rate and depth of cut are equally influenced (48.98%) the surface finish while cutting speed attributed the strongest influence (90.1%). The material removal rate is strongly prejudiced by cutting speed (69.39 %) followed by feed rate (28.94%) whereas chip reduction coefficient is strongly influenced through the depth of cut (63.4%) succeeded by feed (28.8%). TOPSIS significantly optimized the responses with 67.1 % gain in closeness coefficient.

“…MQL was found a useful lubricating method to enhance surface quality and tool life, while cryogenic cooling was found very effective in reducing tool wear and lengthening tool life. However, high costs associated with these cutting fluid supply systems are the principal limitation [33][34][35][36][37].…”

Evaluation of a Novel Controlled Cutting Fluid Impinging Supply System When Machining Titanium Alloys

Abstract:Following a comprehensive review on titanium machining and methods of cutting fluid application, this paper presents a new Controlled cutting fluid impinging supply system (Cut-list) developed to deliver an accurate amount of cutting fluid into the machining zone via well-positioned coherent nozzles based on the calculation of the heat generated. The performance of the new system was evaluated against a conventional flood cutting fluid supply system during step shoulder milling of Ti-6Al-4V using vegetable oil-based cutting fluid. The comparison was performed at different cutting speeds and feed rates. Comparison measures/indicators were cutting force, workpiece temperature, tool flank wear, burr formation and average surface roughness (Ra). The new system provided significant reductions in cutting fluid consumption of up to 42%. Additionally, reductions in cutting force, tool flank wear and burr height of 16.41%, 46.77%, and 31.70% were recorded, respectively. Smaller Ra values were also found with the use of the new system.

“…Thus, there are continuous endeavors to discover a replacement for these cutting fluids. The Minimum Quantity Lubrication (MQL), also called Near to Dry Machining or Micro-Lubrication, is an approach which sprays a small amount of fluid about the range of 10 to 100 ml/h in the form of aerosol to the cutting zone area with the support of compressed air [5][6][7]. It is an appropriate approach for lubrication and effective in machining [8].…”

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.
