Effects of Minimum Quantity Lubrication on turning AISI 9310 alloy steel using vegetable oilbased cutting fluid
Journal of Materials Processing Technology, 2009Co-Authors: M M A Khan, M A H Mithu, N. R. DharAbstract:This paper presents the effects of Minimum Quantity Lubrication (MQL) by vegetable oil-based cutting fluid on the turning performance of low alloy steel AISI 9310 as compared to completely dry and wet machining in terms of chip–tool interface temperature, chip formation mode, tool wear and surface roughness. The Minimum Quantity Lubrication was provided with a spray of air and vegetable oil. MQL machining was performed much superior compared to the dry and wet machining due to substantial reduction in cutting zone temperature enabling favorable chip formation and chip–tool interaction. It was also seen from the results that the substantial reduction in tool wears resulted in enhanced the tool life and surface finish. Furthermore, MQL provides environment friendliness (maintaining neat, clean and dry working area, avoiding inconvenience and health hazards due to heat, smoke, fumes, gases, etc. and preventing pollution of the surroundings) and improves the machinability characteristics.

parameter optimization during Minimum Quantity Lubrication milling of tc4 alloy with graphene dispersed vegetable oil based cutting fluid
Journal of Cleaner Production, 2019Co-Authors: Ming Li, Rongchuang Zhang, Tianbiao Yu, Lin Yang, Hongyu Li, Wanshan WangAbstract:Abstract Minimum Quantity Lubrication has been widely used in the titanium alloy milling process as an advanced and clean means of cooling and Lubrication. The Minimum Quantity Lubrication parameters have a significant influence on the milling characteristics and so, determining an optimal Minimum Quantity Lubrication parameter combination is vital to obtaining the best milling characteristics. In this study, Minimum Quantity Lubrication with graphene-dispersed vegetable-oil-based cutting fluids was adopted in the milling of TC4 alloy, where the cutting fluids were prepared by dispersing graphene nanoparticles into the vegetable-oil-based cutting fluid to improve the milling characteristics of the TC4 alloy. The integrated Taguchi-Principal component analysis-Gray relational analysis optimization method was used to evaluate the effects of the Minimum Quantity Lubrication parameters on the milling characteristics and obtain the optimal Minimum Quantity Lubrication parameter combination. The milling characteristics of TC4 alloy, namely, the milling force, milling temperature, surface micro-hardness, and surface roughness were evaluated and analyzed, and the optimal Minimum Quantity Lubrication parameter combination was obtained. A verification experiment was conducted and the results indicated that all the four milling characteristics were significantly improved after the optimization process. The improvement rates of the milling force, milling temperature, surface micro-hardness, and surface roughness are 18.13%, 13.59%, 8.36%, and 24.82%, respectively. In summary, appropriately chosen Minimum Quantity Lubrication parameters can enhance the Lubrication and cooling properties of the oil film and improve the milling characteristics. The results of this study attest to the feasibility of the integrated Taguchi-Principal component analysis-Gray relational analysis optimization method and provide an experimental basis for the application of graphene additive in Minimum Quantity Lubrication milling.

Improving machining performance of Ti-6Al-4V through multi-point Minimum Quantity Lubrication method
Proceedings of the Institution of Mechanical Engineers Part B: Journal of Engineering Manufacture, 2018Co-Authors: Nilanjan Banerjee, Abhay SharmaAbstract:This article provides an improved Lubrication system for Minimum Quantity Lubrication machining wherein oil is locally supplied and individually controlled at different heating zones during machining operation. The proposed Lubrication method, that is, a multi-point Minimum Quantity Lubrication system, is aimed at improving energy efficiency and environmental friendliness of cutting process. An experimental system is devised in which process parameters, such as air pressure, stroke volume (i.e. amount of oil in one stroke of pump), stroke frequency, and oil distribution factor (i.e. proportion of oil at rake and flank face), are individually controlled for each supply system. The devised system is demonstrated through machining of Ti-6Al-4V. The results of the experimental study on effects of oil Quantity and supply method on specific cutting energy, tool wear, and machined surface quality are presented and discussed and corroborated with scientific evidence. The study suggests that distributing oil at the rake face and the flank face in unequal proportions can be more beneficial than injecting it solely at a single location. The investigation also provides mechanism of multi-point Minimum Quantity Lubrication machining through analysis of adiabatic shear zones, observed in scanning electron microscope images of chips.

Investigation on Multi-Point Minimum Quantity Lubrication Machining
2016Co-Authors: Nilanjan BanerjeeAbstract:The use of cutting fluids during machining operations creates several occupational health risks and many environmental effects as well. However, it is important to reduce the environmental burdens without sacrificing the production rate and product quality. Among various techniques to achieve these goals, the Minimum Quantity Lubrication (MQL) technique has shown promise as an environmentally friendly machining process. Previous investigations suggest that the rake and flank faces of the cutting tool undergo different types of interactions between the tool and workpiece materials. The tribological and thermofluidic phenomena occurring at these two places are quite different. The rake face generates more heat, and the resulting tool wear is responsible for catastrophic failure of the tool. On the other hand, wear at the flank face is more responsible for the surface finish.

Multi-Point Injection Minimum Quantity Lubrication Machining
Materials Science Forum, 2015Co-Authors: Nilanjan Banerjee, Abhay SharmaAbstract:This paper presents a study on Minimum Quantity Lubrication wherein the metal working fluid is injected individually at multiple points in cutting zone, namely, rake face, back of chip and at flank face. A special attachment is developed for injecting aerosol at all possible combinations of one, two, or three forgoing points of injection. A case study on machining of Ti-6Al-4V showing effect of injection schemes on cutting force and surface roughness is presented. Comparison of multi-point injection with dry and flood cooling indicates reduction in cutting force and surface roughness while using different combinations of fluid injection.

Identification of a friction model for Minimum Quantity Lubrication machining
Journal of Cleaner Production, 2014Co-Authors: Nilanjan Banerjee, Abhay SharmaAbstract:In this paper, we present the development of a friction model as a function of the cutting speed and tool feed rate when machining with Minimum Quantity Lubrication. A finite element model of the Minimum Quantity Lubrication process is developed and simulated by considering the friction coefficient as a state variable. The tool-chip friction coefficients for different machining conditions are obtained through inverse modelling and presented as a mechanistic model. The validated model is utilized to understand the effects of machining conditions, temperature, and contact length of the tool-chip interface.
