“…Additionally, β titanium and near β titanium alloys have higher tensile and fatigue strength and are commonly used in aircraft landing gear and aircraft springs (Boyer and Briggs, 2005). Research has shown that Ti-10V-2Fe-3Al (Ti-10-2-3) and Ti-5Al-5Mo-5V-3Cr (Ti-5553) are superior to mature alloys such as Ti-6Al-4V (Ti-6-4) for use in landing gear and load-bearing fuselage applications (Filho et al, 2023;Wu et al, 2018). αÀβ alloys have higher strength and a good combination of properties to ensure stable operation at 315-400 8C.…”

PurposeUnconventional machining processes, particularly ultrasonic vibration cutting (UVC), can overcome such technical bottlenecks. However, the precise mechanism through which UVC affects the in-service functional performance of advanced aerospace materials remains obscure. This limits their industrial application and requires a deeper understanding.Design/methodology/approachThe surface integrity and in-service functional performance of advanced aerospace materials are important guarantees for safety and stability in the aerospace industry. For advanced aerospace materials, which are difficult-to-machine, conventional machining processes cannot meet the requirements of high in-service functional performance owing to rapid tool wear, low processing efficiency and high cutting forces and temperatures in the cutting area during machining.FindingsTo address this literature gap, this study is focused on the quantitative evaluation of the in-service functional performance (fatigue performance, wear resistance and corrosion resistance) of advanced aerospace materials. First, the characteristics and usage background of advanced aerospace materials are elaborated in detail. Second, the improved effect of UVC on in-service functional performance is summarized. We have also explored the unique advantages of UVC during the processing of advanced aerospace materials. Finally, in response to some of the limitations of UVC, future development directions are proposed, including improvements in ultrasound systems, upgrades in ultrasound processing objects and theoretical breakthroughs in in-service functional performance.Originality/valueThis study provides insights into the optimization of machining processes to improve the in-service functional performance of advanced aviation materials, particularly the use of UVC and its unique process advantages.

“…Due to the feed rate is a function of surface roughness, it is expected that increasing feed rate increases surface roughness (Koklu & Çoban, 2020). Accordingly, with lower values of feed rate, roughness traces became more clear and that situation produce rough surface (Wu et al, 2018). The effect of cutting speed can be avoided according to the Figure 2a.…”

Strenx 1100 is one of the most important structural steel characterized by upmost mechanical properties, generally preferred for loadbearing applications at many engineering fields such as marine and crane. Minimum quantity lubrication (MQL) is a method that presents sustainable machining with applying pulverized oil into the cutting zone, proved it by obtaining better machinability characteristics compared to conventional approaches. Surface roughness is a response parameter reflects the quality of a machined part in a certain degree which should be produced as per the industrial requirements. This paper focuses on the surface roughness (Ra) evaluation of Strenx 1100 steel during milling under MQL conditions. Taguchi design of experiments were utilized with combining three levels of cutting speed (vC), feed rate (f) and depth of cut (aP) in order to create L9 orthogonal array. The findings are discussed using analysis of variance (ANOVA), signal-to-noise ratio (S/N) based optimization and 3d surface plots. According to the results, it is observed that the first level of cutting parameters namely vC=75 m/min, f=0.075 mm/rev and aP=0.25 mm need to be selected for optimization of response parameter while feed rate has more influence (66.9%) than depth of cut (22.5%) and cutting speed (0.4%) on surface roughness. Graphical representations exhibit the general trend of surface roughness which provides chance to selection of accurate cutting conditions for required response value.

“…It was found that the depth of surface residual stress increased with the increase of feed per tooth and was not affected by the cutting speed. Wu et al [4] conducted simulation analysis and experimental veri cation of residual stress on milling surface of Ti-10V-2Fe-3Al, and established the formula for the relationship between residual stress and feed speed, cutting speed and depth of cut. Rahul et al [5] studied the effects of critical uncut chip thickness, blade radius, feed per tooth and axial depth on residual stress through nite element model.…”

Residual compressive stress can effectively improve fatigue life of aerospace thin-walled parts. In this study, residual compressive stress control is taken as the target. Firstly, a surface residual stress prediction model is proposed, which considers both machining parameters and milling force-heat. The model of the relationship between milling force, thermal load and residual stress is established, which quantifies the effects of mechanical and thermal loads on the formation of residual compressive stresses. The results show that the feed rate of each tooth and the blade edge radius play an important role in the residual compressive stress of the milling surface. The prediction models of surface residual stress for thermal load, mechanical load, feed per tooth and radius are established. Secondly, the ratio α of the feed rate per tooth fz to the blade edge radius r is calculated. When αxx = 0.42 ~ 0.65 and αyy = 0.36 ~ 0.7, the surface residual compressive stress in X and Y directions of the workpiece reaches the maximum value. Thus, the ratio of the feed rate per tooth fz to the blade edge radius r is optimized to control the mechanical and thermal load quantization. It realizes active control of residual compressive stress on workpiece surface.
