“…According to them, the workpiece and tool develop contact at high nose radius levels, resulting in flank wear proportionate to the depth of cut. Rebecka et al [10] have studied the wear mech-anisms in turning difficult-to-cut alloy using PCBN and PCD insert, and it was observed that the fracture on the flank face was caused owing to deterioration mechanism. It is further found that PCD performed well compared to PCBN in view of life of the tool.…”

Aircraft component manufacturing sector is looking for high precision machining in aircraft components. The present work explores the operability of green manufacturing of Nimonic C263 using dry turning. Nimonic C263 is tough to turn owing to its inherent quality like low conductivity and more work hardening. Therefore, in order to improve this machined surface/integrity, the controlling factors were optimized based on desirability approach for minimum of surface roughness and flank wear during turning of this alloy using CBN insert. L27 orthogonal array was chosen to carry out the experiment. The effects of controlling factors, such as cutting speed ( V ), feed rate ( S ), and cut penetration/depth of cut ( a p ) on the outputs, were also explored. The feed rate was a major impact to affect surface finish and flank wear. The average error percentage between the experimental and RSM models for surface finish was 4.76 percent and 2.79 percent for flank wear.

“…The consequence of a segmented chip is a high-frequency thermomechanical alternating load on the cutting tool. Therefore, segmented chip formation can be used as a signi cant factor for the high tool wear during the machining of Ti-6Al-4V [18,19]. In addition, chip formation signi cantly affects the components surface and subsurface properties [9,20,21].…”

Titanium and titanium alloys have high strength at low density, good corrosion resistance and excellent biocompatibility. Therefore, the use of titanium materials is well established in high performance applications such as aerospace and biomedical. However, titanium and titanium alloys such as Ti-6Al-4V have low thermal conductivity, exhibit unfavorable chip formation with typical segmented chips, and have high chemical affinity to surrounding elements such as oxygen. Tool wear and the properties of the component surface and sub-surface are significantly influenced by the presence of oxygen and resulting chemical interactions. Among other things, chemical reactions such as oxidation occur due to the high temperatures and presence of oxygen. In this work, the chip formation of Ti-6Al-4V at different cutting speeds in discontinuous orthogonal cutting process under different atmospheres is investigated. A conventional air atmosphere, a pure argon atmosphere, and a silane-doped atmosphere were used. The oxygen content of the silandoped argon atmosphere corresponds to an extremely high vacuum (XHV), which is practically oxygen-free. It was found that chip formation is affected by the surrounding atmosphere. At the cutting speed vc = 80 m/min, non-periodic segmentation is present under oxygen-free atmosphere, while segmental chip formation occurs under air. This is accompanied by up to 16.5% lower feed force under inert gas atmosphere, which is due to reduced friction caused by the use of an oxygen-free atmosphere.

“…Various methods to improve a titanium alloy's machinability include employing surface coating [7], a superhard tool [8], cryogenic lubrication [9], structure optimization of the tool [10], bionic surface texture [11], and micromachining processes [12][13][14], etc. In recent years, ultrasonic machining methods have been widely studied for improving cutting performance at home and abroad.…”

A polycrystalline diamond (PCD) tool is employed in cutting various titanium alloys because of its excellent properties. However, improving the cutting performance of titanium alloys is still a challenge. Here, an experimental investigation on the influence of ultrasonic vibration-assisted machining (UVAM) of Ti6Al4V titanium alloy on the cutting performance and action mechanism was studied using a PCD tool. Cutting force, machined surface, surface adhesion, and wear morphology were analyzed. The results indicated that UVAM can effectively improve cutting performance. It was found that there was serious adhesion and wear of slight fragments close to the cutting edge after ultrasonic-assisted dry milling. Furthermore, the action mechanism of UVAM in improving cutting performance was discussed and analyzed from the perspective of intermittent cutting.
