“…Based on this, it is evident that the MQL system, with a flow of 30 mL/h and in the form of droplets, showed better efficiency in the aspect of lubricity. These results are in accordance with the study carried out by Ribeiro Filho et al., 6 where the authors demonstrated that MQL has better efficiency in lubricating a form tapping process than emulsion, decreasing not only the torque value but also the burr formation at the exit of the holes drilled into the workpiece.

Modern industry faces a great challenge: the production of consumer goods based on a triangle comprising low costs, low production time and high quality. The optimisation of modern manufacturing processes should seek not only the reduction of manufacturing time but also the reduction of mineral resources and electric energy consumption. In the context of metalworking, considering tapping processes, studies on the use of minimum quantity of lubricant are minimal and scarce. Hence, this study deals with the application of minimum quantity of lubricant and emulsion to the processes of form and machine tapping. To this end, 7075-T651 aluminium alloy workpieces were threaded using both tapping processes at three cutting/forming speeds. M10 threads with a pitch of 1.5 mm were considered the standard profile. Torque and thrust force were monitored, and three threading heads were employed in the experimental tapping tests. According to the results, it can be concluded that the best option was to use minimum quantity of lubricant in order to reduce environmental impact, given its efficient disposal of fluids and compatibility with Softsynchro threading heads, which kept both torque and axial force close to the mean values. Furthermore, this threading head model was also the best for reducing the manufacturing time of the threads.

“…Ribeiro Filho et al. 6 compared different vegetable fluids to determine the best fluid in terms of efficiency when MQL was used. According to the authors, it is possible to apply MQL in conjunction with specific fluids not only to machine tapping but also to the forming process.…”

“…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.

“…The use of vegetable oil in metalworking applications may alleviate the harmful effects of mineral-based cutting fluids. Around the world, many investigations are in progress to develop new biodegradable cutting fluids based on various vegetable oils available (Alves & Oliveira, 2006;Belluco & De Chiffre, 2004;Filho et al, 2017;Khan et al, 2009;Shashidhara & Jayaram, 2010). In the same manner, the environmental friendliness of the minimal fluid application scheme can be enhanced by replacing mineral oil-based cutting fluid with a vegetable oil-based cutting fluid.…”

In the present work, an attempt was made to use vegetable oil as cutting fluid during minimal fluid application to make the process more environment friendly. Coconut oil was selected as the vegetable oil in this study considering its availability, physical properties, and lubricating ability. The effect of newly formulated coconut oil-based emulsified cutting fluid on cutting performance during turning of hardened AISI 4340 steel with the minimal fluid application was investigated. It was observed that the coconut oil-based cutting fluid offered better cutting performance in terms of tool wear, surface roughness, cutting force, cutting temperature, and tool chip contact length when compared to mineral oil-based cutting fluid and raw coconut oil. It was also observed that the percentage of concentrate in the cutting fluid was to be maintained as 30% to achieve better cutting performance. The use of coconut oil-based cutting fluid holds promise as an environment friendly alternative for mineral oil-based cutting fluid.
