“…However, the amount of lubricant varies considerably between various studies. For example, according to Tschätsch and Reichelt the range of cutting fluid consumption is between 50 ml/h to 2 l/h [4] whereas other studies have reported even lower amounts of 10-100 ml/h [5][6][7]. Nevertheless, the consumption of cutting fluid is known to be significantly reduced in MQL compared to conventional flood cooling where the typical rate is approximately 1200 l/h [7].…”

Government legislation and public opinion are the main drivers behind the movement of manufacturing companies towards sustainable production. Fundamentally, companies want to avoid future financial penalties and the industry is therefore under pressure to adapt new techniques and practices in order to become environmentally friendly. The cost efficiency of metal cutting operations is highly dependent on accuracy, excellent surface finish and minimised tool wear and, to this end, has traditionally made abundant use of cutting fluid in machining operations. However, these cutting fluids have been a major contributor to environmental and health issues. In recent years an enormous effort to eradicate these adverse effects has been made with one important focus being the implementation of minimum quantity lubrication (MQL). In the present work the authors have reviewed the current state of the art in MQL with a particular focus on drilling, turning, milling and grinding machining operations.Overall it is concluded that MQL has huge potential as a substitute for conventional flood cooling.

“…Further, they concluded that, the distance to the nozzle is critical to the MQL performance. Although majority of the literature points out the advantages, [23] has mentioned that MQL lacks cooling effect, and lushing cut chip away from the work area. As they explained, due to those reasons, MQL is not a viable for machining hard-to-cut metals as well as drilling or grinding deep-holes.…”

Keywords AbstractCutting luid Machining MQL Tool steels Received: 8 January 2018Accepted: 31 January 2018 Published: 13 February 2018This study is focused on evaluating newly developed chilled-emulsion Minimum Quantity Lubrication (MQL) method on machining hard-to-cut metals. Previous research work revealed that, aerosol at 15 0 C provides the optimal tool life and generates the least surface roughness when machining AISI P20 and D2 tool steels at a given cutting speed. In that context, the in luence of varying cutting speeds with MQL aerosol at 15 0 C is further studied in this paper. Three cutting speeds were used as per the tool manufacturer's recommendations. For the aforementioned cutting conditions, tool nose wear were measured and topologies of worn cutting edges were observed and compared. The experimental results revealed that tool wear rate and other forms of damages such as chipping and plastic deformation for different work material have contrasting responses. This indicates that MQL aerosol performance is notably sensitive to work material properties and its bene its as a cutting luid should be further investigated over wider range of materials.

“…To address environmental issues and occupational hazards associated with the cutting fluid mist in shop floors, MQL has been increasingly used. Tai et al (2014) reported that Ford Motor Company has over 400 CNC machines that utilize MQL. However, some of the problems they face in implementing in other machine tools are related to accumulated heat due to low cooling of MQL systems such as in grinding and machining metals with low machinability such as in deep-hole drilling and compacted graphite iron.…”

Machining industry utilizes cutting fluids to increase the performance of the metal cutting process. However, several environmental and health issues limit their usage. Minimum Quantity Lubrication (MQL) with nano cutting fluids is proposed in this paper as a better option for sustainable machining. In the literature, nanofluids are formulated, characterized and tested for their basic properties and performance in different applications. Nanofluids have been found to provide superior thermal and friction reduction qualities depending upon the formulation and application. Combination of vegetable cutting fluids with nanoparticles applied in the form of MQL will provide major environmental benefits without sacrificing the machining performance.
