“…Cutting forces in milling and turning processes can be reduced by using the MQL technique, although for drilling processes, it has been found to have a great dependence of the cutting conditions and hole aspect ratios, because the difficulty of eliminating the chips in deep hole drilling increases the forces. For low aspect ratios, increments up to 27% on tool life have been obtained on drilling processes [32]. The minimum quantity cooling lubrication (MQCL) technique has been found to be a good combination of MQL and low temperature supplement.…”

Titanium is one of the most interesting materials in modern manufacturing thanks to its good mechanical properties and light weight. These features make it very attractive for use in the aeronautical and aerospace industries. Important alloys, such as Ti6Al4V, are extensively used. Nevertheless, titanium alloys present several problems in machining processes. Their machinability is poor, affected by low thermal conductivity, which generates very high cutting temperatures and thermal gradients in the cutting tool. Lubricants and cutting fluids have traditionally been used to solve this problem. However, this option is unsustainable as such lubricants represent a risk to the environment and to the health of the operator due to their different chemical components. Therefore, novel, sustainable and green lubrication techniques are necessary. Dry machining is the most sustainable option. Nevertheless, difficult-to-machine materials like titanium alloys cannot be machined under these conditions, leading to very high cutting temperatures and excessive tool wear. This study is intended to describe, analyse and review the non-traditional lubrication techniques developed in turning, drilling and milling processes since 2015, including minimum quantity of lubricant, cryogenic lubrication, minimum quantity of cooling lubrication or high-pressure coolant. The aim is to provide a general overview of the recent advances in each technique for the main machining processes.

“…Mathew et al [32] investigated the drilling process of titanium aluminide under MQL lubrication. The experiments were conducted under a cutting speed of 72 m/min and feed rate of 0.01 mm/rev with a depth of cut of 10 mm (low aspect ratio) and 37.5 mm (high aspect ratio).…”

“…Mathew's research showed that when drilling under the MQL environment, the drilling temperature was significantly lower compared with dry cutting (see Figure 30). What's more, due to the excess heat generated at the machining area was taken away by the cutting fluid supplied as the mist which can inhibit the built-up edge formation and effectively improve the surface roughness [170]. Murthy et al evaluated the quality characteristics of dimensional deviation of hole diameter, chip thickness and energy consumption etc.…”

Drilling is regarded as the most complex manufacturing process compared with other conventional machining processes. During the drilling process, most of the energy consumed in metal cutting is converted to heat and increases temperature considerably. The resulting thermal phenomena are important since they influence the mode of deformation, the final metallurgical state of the machined surface, and the rate of tool wear. Hence, understanding the temperature characteristics in the drilling process is crucial for enhancing the drill performance and process efficiency. Extensive efforts have been conducted to measure and control the drilling tool temperature successively. However, very few studies have been conducted from a comprehensive perspective to review all the efforts. To address this gap in the literature, a rigorous review concerning the state-of-the-art results and advances in drilling tool temperature is presented in this paper by referring to the wide comparisons among literature analyses. The multiple aspects of drilling tool temperature are precisely detailed and discussed in terms of theoretical analysis and thermal modeling, methods for temperature measuring, the effect of cutting parameters, tool geometries and hole-making methods on temperature and temperature controlling by different cooling methods. In conclusion, several possible future research directions are discussed to offer potential insights for the drilling community and future researchers.

“…On the other hand, MQL has been found as a solution, achieving better results than with flood lubrication. However, MQL has a great dependence on the cutting parameters and the cutting temperature, due to the lack of an effective coolant action [21]. Moreover, these techniques require either specialized equipment or a very expensive one to be implemented in the industrial environment.…”

Surface Integrity and Tool Wear Analysis on Turning of Copper-Nickel 70/30 ASTM B122 Alloy under Low Initial Lubrication

Traditional flood lubrication in machining processes is considered an unsustainable technique. In this paper, the low initial lubrication (LIL) technique is analysed during turning of cupronickel 70/30 alloy, in terms of surface roughness. A tribological analysis has been developed on a pin-on-disk tribometer comparing different lubrication systems, obtaining comparative results of friction and tool wear. It has been found that the tool wear is 73% lower in comparison to flood lubrication. LIL technique shows the ability to reduce the friction coefficient compared to dry machining and leads to improve tool wear in comparison with flood lubrication. The surface integrity evaluation of machined parts finds that the LIL technique can improve the surface roughness under specific machining conditions.
