“…Ahmad Khalil et al stated that lower surface roughness and cutting force were obtained in the machining of Ni-Ti alloy with NanoMQL in vortex-chilled environment compared to other cutting media. 26 Çakıroglu (2021) underlined that the most important parameter in terms of cutting temperature, cutting force and surface roughness in turning Inconel718 under dry, MQL and RHVT cutting environments is the feed rate, and RHVT application can substitute MQL. 23 Kumar et al emphasized that in hard turning of AISI 4340 steel, RHVT cooling showed superior performance in tool life (12.25%), surface roughness (58.26%) and cutting force (55.5%) compared to other cooling conditions.…”

The difficulties in machinability due to the developments in the technical properties of engineering materials increase the importance of machinability indicators such as surface quality, power or energy consumption and tool life in terms of sustainable machining. In this context, the machinability of a copper-beryllium alloy (C17500), which is used in a wide range of industries and also characterized as a hybrid material, was investigated in vortex tube cooling and dry cutting environments. First, turning experiments were performed with a coated carbide tool and varying cutting speed, feed rate and depth of cut. In the experiments, the total energy consumed during turning and the roughness of the machined surfaces were measured, and analysed experimentally and statistically. In the second stage, mathematical models were developed for the total energy consumption and average surface roughness for both cutting environments with the response surface method. As a result, the chip formation process in the turning of the Cu alloy under vortex tube cooling negatively affected the cutting power and positively contributed to the surface quality. Due to the fact that vortex tube cooling creates a cooling effect rather than lubrication, built-up layer/built-up edge (BUL/BUE) formation on the tool cutting edges caused the change in the tool geometry and thus the chip removal process became more difficult and increased the energy consumption. On the other hand, in the vortex tube cooling application, the surface roughness decreased by an average of 31.4% compared to dry cutting. Furthermore, the predictive mathematical models developed for the total energy consumption and the mean surface roughness can be used with high reliability.

“…A previous study have shown that different types of coolant environment approaches are used to machine hard-to-cut materials; therefore, the selection of a suitable coolant approach in the machining technique for machining NiTi SMAs needs to be identified to improve product performance [11]. With this regard, the feasibility of applying hybrid cooling utilising MQNL with vortex environments for turning NiTi SMA F2063 is yet attempted by previous researchers [11]. It is worth to mention that the ASTM F2063 is the standard that specifies the requirements for NiTi alloys to be used as medical devices.…”

Conventional machining of nickel-titanium shape-memory alloys (NiTi SMAs) faces significant challenges as a result of high thermal and mechanical distortions. The phase transformation temperatures of NiTi SMAs are primarily affected by the rise in temperature during the cutting process, which causes poor machinability under the conventional coolant approach. This research explored the effects of hybrid cooling-lubricating of minimal quantity nano-lubricants with compressible-chilled air generated from a vortex tube during the turning of the NiTi alloys. The experimental procedure involved measurement of induced-cutting force components under variable cutting conditions utilising various coolant approaches. A depth of cut, 0.5 mm with cutting speeds of 12.5, 25, and 50 m/min and feed rates of 0.05 and 0.1 rev/min were utilised. The hybrid cooling approach of minimum quantity nano-lubricants with vortex cooling, can increase tool life for most of the tested conditions and has a considerable influence in reducing the inducedcutting force. In contrast, only marginal improvement was observed for the surface roughness when using the same coolant-lubricant strategy.
