“…This can be attributed to the positive effects of nano-fluids. Mia et al [8] detected in their study the surface roughness values of R a mostly higher than 1.0 μm in dry condition. Although they attributed this trend to high-pressure coolant (HPC) system that creates superior surface roughness compared to dry condition, the present study reveals a surface roughness that is even lower than the surface roughness found with HPC assistance in their study.…”

“…On the other side, the increment of surface roughness caused by a higher speed of cutting is credited to increased vibration with such a high speed of cutting. When machining Ti alloy imposing the speed of cutting higher than 100 m/min pose some issue produced by the inherent characteristics [8][9][10]; this has been already discussed in Introduction section. Here, the cutting speed is 200-300 m/min.…”

“…Numerous research works regarding the machining of Ti alloy have been reported with different advanced techniques for implementing MWFs. For instance, Mia et al [8,9] machined the Ti-6Al-4V using a dual oil jet for better chip-tool activity and tool-work interfaces. After the investigations, they reported that the used method had outperformed dry condition; to be specific, reduced tool wear, improved surface finish, lower cutting temperature and force were found.…”

Recently, the urgency of improved machining performance and environmental sustainability has forced the manufacturer to seek for alternative cooling and lubricating agent/technique such as nano-fluid (NF)-assisted minimum quantity lubrication (MQL). In this context, the performances of aluminum oxide (Al 2 O 3), molybdenum disulfide (MoS 2) and graphite (C) NF-impinged MQL in turning of Ti alloy (grade II) using CBN tool were evaluated regarding the cutting force, cutting temperature and surface roughness. The cutting speed, feed rate, approaching angle and cutting conditions (i.e., NFs) were oriented following the Box-Behnken design-of-experiment. The experimental results showed that the graphite NF, compared to Al 2 O 3 and MoS 2 , revealed the lowest cutting force, temperature and roughness. Moreover, it is evident from SEM images that graphite NF revealed a smoother machined surface and tool profile. This smooth tool and workpiece surface profile can be accredited to graphite's role as a nano-lubricant and its breaking ability into smaller NFs under pressure. To make the study complete, the adaptive neuro-fuzzy inference system (ANFIS) was employed to predict, the response surface methodology (RSM) was used to mathematically model, and the composite desirability approach (CDA) was used to optimize the responses. A good agreement between the experimental and modeled observations was found; however, the ANFIS outperformed the RSM. Moreover, the analysis of variance exhibited that the cutting force and temperature were primarily influenced by the cutting speed and the surface roughness was afflicted mostly by the feed.

“…In order to achieve the goal of green and high efficient machining of difficult-to-cut materials, researchers have put forward some green cutting technologies, such as minimal quantity lubrication (MQL) [1,2], high-pressure coolant (HPC) [3,4], electrostatic solid lubrication (ESL) [5,6], and cryogenic cutting(CC) [7][8][9]. Cryogenic cutting has always been seen as one of the effective methods to realize green, high efficiency and high-quality processing of difficult-to-cut materials.…”

This paper first develops a cryogenic cutting system with adjustable jet temperature (− 196~20°C), and then carries out a series of dry cutting and cryogenic turning experiments for titanium alloy. Metallographic microscope is used to observe the chip morphology of titanium alloy and the geometric characteristic parameters of the chip are measured using a Digimizer image measurement software. The influence of cutting speed and cooling conditions on the chip morphology, chip height ratio, and serrated pitch has been analyzed. The experimental results reveal that the cutting speed and cooling conditions play significant roles on the chip morphology and serrated characteristics of titanium alloy. During the cryogenic cutting process, with the increase of cutting speed, the chip height ratio and serrated pitch of titanium alloy chip increase. It has been found that under the condition of cryogenic cutting, the lower jet temperature, the more obvious serrated characteristic of titanium alloy chip. It is also found that the fibrous adiabatic shear band exists in the shear zone; the chip height ratio and serrated pitch remarkably increase.

“…They discussed the use of the transfer function approach for improving mathematical modelling and adaptive control of the process dynamics of turning operations. Mia et al [26] performed turning experiments on Ti-6Al-4V alloy under dry and high-pressure cooling conditions. The cutting inserts used were coated carbides and the surface quality (in terms of speed and feed) as well as tool wear (in terms of machining time) was discussed.…”

A conventional manual lathe electric motor drives the multi-stage gearbox transmitting torque to the spindle so that the workpiece makes contact with the machine tool at a given speed. The cutting speed is proportional to both the diameter of the workpiece and the spindle speed, however, the increments in spindle speed are limited. Manual lathe machines cannot be regulated at the optimum cutting speeds for all diameters. An innovative modernization of the main driveline of a TSB16 manual lathe is proposed in this paper, allowing for a cost-effective system for digital control of spindle speeds using an inverter. The inverter is controlled using an 8-bit AO (analog output) converter with special software developed with Visual Basic. The results of the analysis and various test runs with this new system for automated control of spindle rotation, showed that the required cutting speed can be achieved for any workpiece diameter. The deviation of cutting-speed of the upgraded system for any turning diameter is greatly reduced in comparison with the deviation of cutting-speed of a manual lathe. Finally, tests on this versatile system demonstrated a cost-effective method for modernizing the drive system of conventional lathe machines.
