Abstract

Although there have been great advances in the development of cutting tool materials which have significantly improved the machinability of a large number of metallic materials, including cast irons, steels and some high temperature alloys such as nickel-based alloys, no equivalent development has been made for cutting titanium alloys due primarily to their peculiar characteristics. This paper reviews the main problems associated with the machining of titanium as well as tool wear and the mechanisms responsible for tool failure. It was found that the straight tungsten carbide (WC/Co) cutting tools continue to maintain their superiority in almost all machining processes of titanium alloys, whilst CVD coated carbides and ceramics have not replaced cemented carbides due to their reactivity with titanium and their relatively low fracture toughness as well as the poor thermal conductivity of most ceramics. This paper also discusses special machining methods, such as rotary cutting and the use of ledge tools, which have shown some success in the machining of titanium alloys.

Enhancing machining efficiency of Ti-6Al-4V through multi-axial ultrasonic vibration-assisted machining and hybrid nanofluid minimum quantity lubrication
2024, Journal of Manufacturing Processes
Ti-6Al-4V offers a balance of good strength with lightweight properties. Yet, Ti-6Al-4V poses machining challenges, including low thermal conductivity, chemical adhesion to cutting tools, and chip removal difficulties. To improve machining efficiency, Ultrasonic Vibration-Assisted Machining (UVAM) has emerged as a promising approach. UVAM has demonstrated reduced tool wear, cutting forces, and improved surface quality compared to Conventional Machining (CM). Additionally, Minimum Quantity Lubrication (MQL) methods offer sustainable coolant alternatives, with recent research focusing on Nanofluid-MQL (NMQL) and Hybrid Nanofluid-MQL (HNMQL) for enhanced performance. Although there exists a body of literature showcasing the promising effects of UVAM and MQL methods individually, comprehensive investigations into the synergistic effects of these methodologies remain limited. This study addresses these critical research gaps by conducting a systematic examination of combined application of multi-axial UVAM and HNMQL. Specifically, it delves into the comparison of different vibration directions within UVAM, evaluates the effectiveness of UVAM when combined with cutting fluids incorporating Al₂O₃ and CuO nanoparticles in NMQLs and HNMQLs, and contrasts these novel approaches with conventional machining methods. The study unfolds in three distinct stages. The first stage examines the ultrasonic cutting mechanism and its combined application with the MQL technique. In the second stage, the study investigates the physical properties of the cutting fluids, including contact angle and surface tension. The final stage encompasses slot milling operations, where an array of parameters such as cutting forces, surface roughness, surface topography, surface texture, and the occurrence of burr formations are rigorously analyzed. The results demonstrate that the combination of multi-axial UVAM with HNMQL yields substantial advantages over traditional machining methods. Notably, it leads to a remarkable reduction in cutting forces (up to 37.6 %) and surface roughness (up to 37.4 %). Additionally, this combination engenders the production of highly homogeneous and uniform surface textures, characterized by minimal surface defects and a significantly diminished occurrence of burr formations. These findings underscore the potential of multi-axial UVAM combined with HNMQL as a promising approach in enhancing the machining of Ti-6Al-4V, thus offering a pathway to enhance the efficiency and precision of aerospace component manufacturing processes.
Review of current best-practices in machinability evaluation and understanding for improving machining performance
2024, CIRP Journal of Manufacturing Science and Technology
Machinability is a generalized framework that attempts to quantify the response of a workpiece material to mechanical cutting, which has been developed as one of the key factors that drive the final selection of cutting parameters, tools, and coolant applications. Over the years, there are many attempts have been made to develop a standard evaluation method of machinability. However, due to the complexity of the influence factors, i.e., from work material and cutting tool to machine tool, that can affect the materials machinability, currently there is no uniquely defined quantification of machinability. As one of the outcomes from the CIRP’s Collaborative Working Group on “Integrated Machining Performance for Assessment of Cutting Tools (IMPACT)”, this paper conducts an extensive study to learn interacting machinability parameters to evaluate the overall machining performance. Specifically, attention is focused on recent advances made towards the determination of the machinability through tool wear, cutting force and temperature, chip form and breakability, as well as the surface integrity. Furthermore, the advanced methods that have been developed over the years to enable the improvement of machinability have been reviewed.
Research on effect of ultra-high pressure coolant supplied from flank face in end milling of Ti-6Al-4V supported by CFD simulations
2024, Journal of Manufacturing Processes
In end milling of difficult-to-cut material such as Ti-6Al-4V, thermal wear is one of the main reasons leading to short tool life. High temperature occurred at the cutting zone during cutting process advances adhesion wear and diffusion wear at rake face, accelerates thermal plastic deformation. Furthermore, high temperature could also accelerate flank wear and promote adhesion wear at flank face. Consequently, machining precision of tool will degrade. Ultra-high pressure coolant (UHPC) is one of the well-known cooling/lubrication methods to solve this problem. In this paper, effect of UHPC on end mill flank face have been studied. To accomplish this, we designed an end mill with flank face coolant supplied from a close distance. The influence of coolant nozzle's direction has been studied by computational fluid dynamics (CFD) simulations. The result explains how the direction of the coolant nozzle impact on flow condition on the tool surface. The end mill was manufactured based on simulations by additive manufacturing. Experimental results including flank wear, surface roughness and cutting temperature demonstrate advantages of UHPC in end milling compared to dry cutting and flood coolant. The micro morphology of the worn areas on flank face and rake face further supports the advantages of UHPC.
On wear of TiAlN coated tools with and without NbN overlayer in machining titanium alloys
2024, International Journal of Machine Tools and Manufacture
Finding a wear resistant coating for cemented carbide cutting tools in the machining of difficult to cut Ti alloys is a challenge due to their high strength and chemical reactivity. Tool manufacturers recommend physical vapor deposited (PVD) Ti_xAl_1-xN (x = 0.4–0.7), and an extra NbN overlayer has shown promising potential. This study explores wear mechanisms of PVD Ti_0.45Al_0.55N with and without NbN overlayer and its WC-Co substrate in machining Ti alloys. To achieve an accurate understanding of tool-chip-workpiece interaction and related wear mechanisms, several approaches were employed. Tests with controlled variation of cutting speeds were complemented by process freezing experiments using the quick stop method and imitational experiments of diffusion couples. Advanced microscopy techniques were employed for accurate detection of wear products and phenomena across length scale. Findings reveal that any new design of coatings for Ti machining must combine both high mechanical integrity and resistance to diffusional dissolution and oxidation. Observed diffusional loss of Al and N from the coating results in a TiN layer which is mechanically weaker than the original coating, while the NbN overlayer reduces the Al diffusion rate, but NbN is subjected to diffusional dissolution itself. On dissolution, Nb stabilizes β-Ti and thus facilitating loss of Al, but the observed formation of intermetallic Nb₃Al at the NbN–Ti interface works as a diffusion barrier. However, brittle Nb₃Al can be more easily removed during machining. It was found that the coating retains longest on the edge line and protects the tool edge from failure because substrate cemented carbide wears at a faster rate than the coating with outward diffusion of C from WC grains and Co binder.
Inconel 718 alloy strengthening mechanism and fatigue life of microtexture-induced microjet coupled with cavifying water jet
2024, Vacuum
This research investigates how waterjet treatments enhance the durability of pre-textured Inconel 718 alloy surfaces and their subsequent impact on fatigue life. By harnessing the microjet effects created by the fluid jet process on the microtextured surfaces, the study uses finite element and fatigue analysis models developed in ABAQUS and Fe-safe to examine residual stresses and surface roughness post-treatment. The study confirmed through experiments that waterjet processing significantly boosts the alloy's resistance to fatigue by generating substantial compressive stresses on the surface. The highest compressive stress was achieved with high-density waterjets (WJ-Hd), followed by low-density (WJ-Ld) and standard waterjets (WJ), with WJ-Hd generating stress levels more than double that of WJ and nearly 40% higher than WJ-Ld. The surface roughness was found to increase with jet velocity, affecting the central and edge areas of the sample differently depending on the waterjet type. In fatigue tests, the order of performance from highest to lowest was WJ-Hd, WJ-Ld, WJ, and untreated samples. High-density waterjets extended the fatigue life considerably by preventing crack formation and growth, suggesting that such treatments could significantly improve the endurance and integrity of Inconel 718 alloy surfaces. This study contributes new understanding to the field of waterjet strengthening for Inconel 718 alloys with pre-fabricated microtextures.
Experimental investigation of micro-pillar textured WC inserts during turning of Ti6Al4V under various cutting fluid strategies
2024, Journal of Manufacturing Processes
Continuous shearing of the chip under the condition of seizure at the chip/tool interface has been recognized as a major source of heat input to the tool. This heat is unsafe for the tool life as it exhibits high plastic deformation of the sharp cutting edge under the action of high compressive stresses, leading to flank and crater wear. To diminish the severity of this condition, it seems impelling to decrease the chip/tool interface contact and enhance cutting fluid (air/liquid) penetration and retention into this seizure zone. Surface texturing of cutting tools has been gaining popularity in this aspect. This work extensively studies a turning operation using innovative textures fabricated using the Reverse Micro Electrical Discharge Machining (RμEDM) process on the tool surface. These textures, in the form of arrayed micro-pillars, were tested under dry, compressed air, MQL, and wet conditions during the turning of Ti6Al4V. The objective is to understand the ability of these micro-pillars to influence the cutting action in terms of tool wear, contact area, severity of adhesion, surface roughness of the work material, and chip morphology. It is visible from the overall experimental results that the textured pattern has the potential to decrease the chip/tool contact area by promoting tighter curling of the chips. A maximum of 52.3 % reduction in chip curl radius is achieved under compressed air condition. The textures assist in reducing the intensity of adhesion as high as 68.22 % on the chip/tool interface under dry machining and, hence, the temperature input to the tool. A similar deduction can be made from the reduced flank wear width with a maximum reduction of 18.45 % under wet conditions, indicating prolonged sharpness retention of the cutting edge. The measured feed forces also concur with the reduced contact area at the interface. A reduction of 30.96 % in the contact area is achieved, corresponding to a 19.73 % reduction in feed force under wet machining condition.
