“…Ultrasonic vibration-assisted cutting enables excellent machining results not only for super hard or soft materials like resins, copper, hard alloys, and ceramics [2], but also for non-homogeneous materials found in the aviation industry, such as carbon fiber reinforced plastic (CFRP), where it helps prevent delamination [3,4]. Additionally, it proves beneficial for processing titanium alloys, enabling high machining efficiency and achieving a good surface finish [5,6]. Vibration-assisted cutting has found application in various cutting operations, including turning [7],…”

“…However, their low thermal conductivity, high chemical activity and small elastic modulus are rendered them as di cult-to-cut materials as high cutting temperatures and severe tool wear are easily induced during machining [4,5]. Conventionally, ood cooling technologies is majorly employed during milling processes.…”

Milling of titanium alloys is usually associated with a high cutting temperature and severe tool wear. Therefore, ood cooling technologies were conventionally employed for prolonging the tool life and improving the machined surface quality. However, a negative impact on the environment and waste disposal problems caused by a vast quantity of metalworking uids used in the process has become signi cant. In this study, a new machining method called "cold air electrostatic minimum quantity lubrication (CAEMQL)" is proposed for machining titanium alloys Ti-6Al-4V. The milling performance of CAEMQL was systematically assessed in terms of cutting force, cutting temperature, surface roughness, tool life, tool wear and chip morphology, using minimum quantity lubrication (MQL), electrostatic minimum quantity lubrication (EMQL) and cold air minimum quantity lubrication (CAMQL) as benchmarks. It was found that CAEMQL resulted in an improved critical heat ux and steady-state heat transfer performance compared with MQL, EMQL and CAMQL, which thus produced a lower milling force, smaller milling temperature, better surface quality and less tool wear. The degrees of chip segmentation were enhanced with less deformation for CAEMQL due to its synergistic cooling and lubrication effect .

Titanium alloys are widely used in various fields because of their high strength, excellent corrosion resistance, and high heat resistance. As a new advanced titanium alloy for aviation, TC21 titanium alloy has high strength and poor machinability. It is of great significance to study the cutting mechanism of this alloy and the methods to improve the machinability of aircraft. In this paper, aiming at the difficult machinability of titanium alloy TC21, EPH online heating assisted cutting method is put forward for the first time. During the cutting experiment, the TC21 alloy sample was heated to a variety of temperatures through the electric pulse thermal heat technique. Chip shape and cutting force under different heating temperatures were obtained by cutting experiments. In order to study the influence of the heat-assisted cutting process on the machining of TC21 alloy, the orthogonal finite element model was proposed to simulate the heat-assisted cutting process of TC21 alloy. Through this simulation, chip formation, cutting force, and cutting temperature variation were all obtained. The chip formed by the simulation was in accordance with the actual chip. The results demonstrate that the influence of heat-assisted machining on chip morphology of titanium alloy is relatively small, but it has a significant influence on cutting force and surface roughness. The results show that when the sample is heated to 600°C, the surface quality is the best and cutting force can be reduced by more than 40%.
