“…Consequently, this improves surface finish of workpiece and the tool life. Namb and Paulo [62] investigated machinability of Ti-6Al-4V at varied cutting speed of 45, 90, 135 m/min, depth of cut of 0.5 and 0.75 mm and feed rate of 0.1,0.2 and 0.3 mm/ rev. They found that tool life increased by 30% in comparison with dry machining when cutting fluid containing 75% water was applied.…”

Machining is one of the major contributors to the high cost of titanium-based components. This is as a result of severe tool wear and high volume of waste generated from the workpiece. Research efforts seeking to reduce the cost of titanium alloys have explored the possibility of either eliminating machining as a processing step or optimising parameters for machining titanium alloys. Since the former is still at the infant stage, this article provides a review on the common machining techniques that were used for processing titanium-based components. These techniques are classified into two major categories based on the type of contact between the titanium workpiece and the tool. The two categories were dubbed conventional and non-conventional machining techniques. Most of the parameters that are associated with these techniques and their corresponding machinability indicators were presented. The common machinability indicators that are covered in this review include surface roughness, cutting forces, tool wear rate, chip formation and material removal rate. However, surface roughness, tool wear rate and metal removal rate were emphasised. The critical or optimum combination of parameters for achieving improved machinability was also highlighted. Some recommendations on future research directions are made.

“…An alternative to machining without a cutting fluid is flood cooling. Compared with dry machining, it has been found to significantly improve surface quality, reduce total blade wear by 30%, minimize diffusive and adhesive wear, and substantially reduce the adhesion of chips to the blade's face, increasing productivity [3,4]. Even better results are achieved when the cutting fluid is fed under pressure.…”

Due to their poor machinability, the machining of titanium alloys without a machining fluid is practically impossible. One of the fluid feeding methods, which is also eco-friendly, is minimum quantity lubrication (MQL). This paper presents the results of research into the dry and MQLassisted machining of alloy Ti-6Al-4V. In the literature on the subject, there are studies on the influence of MQL on tool life, cutting forces, and the most commonly used roughness parameters Ra and Rz. In this paper, MQL's impact on the values of parameters Rq, Rt, Rp, Rv, Rsk, and Rku is shown. In addition, the possibility of improving the surface quality of the selected titanium alloy using wiper geometry inserts combined with MQL is assessed. The exemplary images of the surface, machined using tools of conventional and wiper geometry, in dry and MQL conditions are also shown. Thanks to the wide range of the measured and analysed roughness parameters the results presented in this paper provide a basis for a comprehensive assessment of the geometric and functional features of the surface of alloy Ti-6Al-4V after dry and MQL-assisted turning.

“…The use of inserts further increased machinability of the titanium alloy. The influence of coolant on machining Ti-6Al-4V has also been investigated [12]. Findings showed an improved Ra value of 1.3µm with coolant as against 1.4µm without coolant.…”

High temperature generated and stresses induced as a result of turning of Ti6Al4V results in poor surface finish. The aim of this study was to investigate the effect of coolant temperature on the surface roughness of Ti6Al4V which is a core material used as an implant. A cooling system was developed to reduce the temperature of the coolant (soluble oil) from room temperature to 2oC. Ti6Al4V was turned in dry and cooled (at temperatures 5, 7, 9 and 11 oC) conditions. The experiment was designed using central composite design of (Response surface methodology) Design Expert 11.0 to generate an array and optimize the machining parameters. The machining parameters used were cutting speed, feed rate, depth of cut and coolant temperature. Results analyses show that cutting speed and depth of cut had considerable effect on surface roughness of Ti6Al4V. Surface roughness reduced when coolant temperature was reduced. The results of this study shows that turning Ti6Al4V at a very low cutting temperature will ensure a better surface finish.
