“…RSM method suggested that both the surface roughness and tool wear fit linear models with relatively high R 2 of 92% and 99%, respectively. The linear models representing the two responses can be described as functions of the cutting fluid concentration (c), cutting speed (v), feed rate (f), and cutting tool type, and are expressed as in equation [2]. The coefficients' values for the surface roughness and tool wear (for different tool types) are shown in Tables 5 and 6, respectively.…”

The paper details experimental and optimisation results for the effect of cutting fluid concentration and operating parameters on the average surface roughness (Ra) and tool flank wear (VB) when flooded turning of Ti-6Al-4V using water-miscible vegetable oil-based cutting fluid. Cutting fluid concentration, cutting speed, feed rate, and cutting tool were the control variables. Response surface methodology (RSM) was employed to develop an experimental design and optimise Ra and VB using linear models. The study revealed that cutting fluid concentration has a little influence on Ra and VB performance, while Ra was strongly affected by feed rate and cutting tool type. The developed empirical model also suggested that the best parameters setting to minimise Ra and VB are 5%, 58 m/min and 0.1 mm/rev for cutting fluid concentration, cutting speed, and feed rate, respectively, using H13A tool. At this setting, the predicted surface roughness and tool wear were 0.48 and 30 μm, respectively. In the same vein, tool life and micro-hardness tests were performed at the suggested optimum cutting condition with different cutting speeds. A notable decrease in tool life (82.3%) was obtained when a higher cutting speed was used.

“…However, the same properties that give the alloys superior qualities also make them notoriously difficult to cut, owing to their low thermal conductivities, high dynamic shear strength and high hardness (e.g. up to 360 HV for Ti-6Al-4V), and high chemical reactivity at elevated temperatures [1,2]. Low thermal conductivity (e.g.…”

“…The authors [15] found that the use of flux based on this powder composition contributes to forming a thicker and denser layer of intermetallides due to high temperature. The peculiarity of works [16] is that this composition of titanium-aluminium powders is limited by their existence's physical and chemical conditions. In many cases, increased requirements are placed on the performance characteristics of parts with design elements that are made based on titanium alloys [17].…”

The article presents a systematic block diagram for manufacturing TiAl titanium alloys. Based on the developed block diagram of TiAl components, the main already known stages of powder metallurgy manufacturing technology were improved. Based on the obtained chemical reaction of structurally inhomogeneous materials, the intermetallic phase relationship of titanium aluminides was revealed. It is studied that in the zone of interaction of the composition of titanium and aluminium components, a certain thickness of the transition layer is formed, which practically does not change with increasing exposure time. The crystallization process of inhomogeneous TiAl materials was studied in more detail using the constructed crystal lattice of titanium alloys. As a result, the formation of an atomic grid in space was observed. It should also be noted that the recognition of individual areas in microstructural images was carried out using the Smart-eye software package. The microscopic analysis allowed us to predict the main structural characteristics of TiAl components. In particular, to carry out more detailed control of the particles of TiAl components, their density, porosity, relationships with each other, the shape and size of TI and Al powders. The structure of the interaction of TiAl materials and the interpolation dependence of the formed intermetallic layer are also presented. Based on the conducted research, the quality indicators of parts with structural elements, particularly gears, have been improved.

“…Additionally, it provides cost savings in machining. The cutting liquid or coolant's or MWF's main objective is to expel the heat produced by friction between the workpiece and the cutting tool, which ultimately decreases the upsurge in temperature of the cutting tool [8]. Besides, cutting fluid also aids in the flushing of the produced chips during the machining process.…”

The present research attempts to develop a hybrid coolant by mixing alumina nanoparticles with cellulose nanocrystal (CNC) into ethylene glycol-water (60:40) and investigate the viability of formulated hybrid nanocoolant (CNC-Al2O3-EG-Water) towards enhancing the machining behavior. The two-step method has been adapted to develop the hybrid nanocoolant at various volume concentrations (0.1, 0.5, and 0.9%). Results indicated a significant enhancement in thermal properties and tribological behaviour of the developed hybrid coolant. The thermal conductivity improved by 20-25% compared to the metal working fluid (MWF) with thermal conductivity of 0.55 W/m℃. Besides, a reduction in wear and friction coefficient was observed with the escalation in the nanoparticle concentration. The machining performance of the developed hybrid coolant was evaluated using Minimum Quantity Lubrication (MQL) in the turning of mild steel. A regression model was developed to assess the deviations in the tool flank wear and surface roughness in terms of feed, cutting speed, depth of the cut, and nanoparticle concentration using Response Surface Methodology (RSM). The mathematical modeling shows that cutting speed has the most significant impact on surface roughness and tool wear, followed by feed rate. The depth of cut does not affect surface roughness or tool wear. Surface roughness achieved 24% reduction, 39% enhancement in tool length of cut, and 33.33% improvement in tool life span. From this, the surface roughness was primarily affected by spindle cutting speed, feed rate, and then cutting depth while utilising either conventional water or composite nanofluid as a coolant. The developed hybrid coolant manifestly improved the machining behaviour.
