“…In the same vein, both systems exhibited marginal reductions in average workpiece temperature with increased cutting speed and feed rate. This could be due to the increased fluid flow rate associated with increasing cutting energy, which improved the fluid's ability to dissipate heat [62,63]. Figure 7 demonstrates the tool flank wear data obtained for both systems in various cutting conditions.…”

Abstract:Following a comprehensive review on titanium machining and methods of cutting fluid application, this paper presents a new Controlled cutting fluid impinging supply system (Cut-list) developed to deliver an accurate amount of cutting fluid into the machining zone via well-positioned coherent nozzles based on the calculation of the heat generated. The performance of the new system was evaluated against a conventional flood cutting fluid supply system during step shoulder milling of Ti-6Al-4V using vegetable oil-based cutting fluid. The comparison was performed at different cutting speeds and feed rates. Comparison measures/indicators were cutting force, workpiece temperature, tool flank wear, burr formation and average surface roughness (Ra). The new system provided significant reductions in cutting fluid consumption of up to 42%. Additionally, reductions in cutting force, tool flank wear and burr height of 16.41%, 46.77%, and 31.70% were recorded, respectively. Smaller Ra values were also found with the use of the new system.

“…and the behaviour of the materials due to the dynamic of material removal process. This is especially problematic for thin, tiny, difficult-to-machine materials [19][20] chining machines are designed for specific profile geometry fabrication. On most micro machining processes, cutting forces is one of the greatest challenges.…”

This study explores the feasibility of the hybrid wire electro discharge turning (HWEDT) process for the fabrication of micro components in the defence communication, surveillance and navigation technologies have clear developments for micro sized components that are mainly driven by advancements in micro sensors and microelectronics instruments. The rapid innovation in this sect technological development of micro micro-aerial vehicles (MAV) and micro specifications. From a manufacturing perspective, most of the parts fabrication that is precise, complex and leaves no room for error in the manufacturing process; which is perfect for HWEDT.

“…All the above models provide insightful information on temperature prediction of tool during titanium alloy machining, but they all deal with dry cutting. Hadzley et al [7] developed a finite element machining model for high-pressure jet-assisted machining of Ti-6Al-4V alloy. The model was used to simulate interactions between the fluid and solid structure in order to study the effect of coolant pressure on chip formation, cutting force, and cutting temperature.…”

In this study, a heat transfer model of machining of Ti–6Al–4V under the application of atomization-based cutting fluid (ACF) spray coolant is developed to predict the temperature of the cutting tool. Owing to high tool temperature involved in machining of Ti–6Al–4V, the model considers film boiling as the major heat transfer phenomenon. In addition, the design parameters of the spray for effective cooling during machining are derived based on droplet–surface interaction model. Machining experiments are conducted and the temperatures are recorded using the inserted thermocouple technique. The experimental data are compared with the model predictions. The temperature field obtained is comparable to the experimental results, confirming that the model predicts tool temperature during machining with ACF spray cooling satisfactorily.
