“…Different types of holes are important structural features for metal components to achieve specific functions. Many types of hole-forming methods are currently available, but drilling is the most extensive and practical for functional components of materials that are difficult to process, accounting for approximately 30%-40% of mechanical processing [98]. However, drilling machining of difficult-to-cut materials, such as titanium alloy, is characterized by low heat dissipation rate, large torque, difficult chip removal, serious bit bonding wear, and intermittent chip accumulation, which affect not only processing efficiency but also machining accuracy and workpiece surface quality [99].…”

Cutting fluid plays a cooling-lubrication role in the cutting of metal materials. However, the substantial usage of cutting fluid in traditional flood machining seriously pollutes the environment and threatens the health of workers. Environmental machining technologies, such as dry cutting, minimum quantity lubrication (MQL), and cryogenic cooling technology, have been used as substitute for flood machining. However, the insufficient cooling capacity of MQL with normal-temperature compressed gas and the lack of lubricating performance of cryogenic cooling technology limit their industrial application. The technical bottleneck of mechanical—thermal damage of difficult-to-cut materials in aerospace and other fields can be solved by combining cryogenic medium and MQL. The latest progress of cryogenic minimum quantity lubrication (CMQL) technology is reviewed in this paper, and the key scientific issues in the research achievements of CMQL are clarified. First, the application forms and process characteristics of CMQL devices in turning, milling, and grinding are systematically summarized from traditional settings to innovative design. Second, the cooling-lubrication mechanism of CMQL and its influence mechanism on material hardness, cutting force, tool wear, and workpiece surface quality in cutting are extensively revealed. The effects of CMQL are systematically analyzed based on its mechanism and application form. Results show that the application effect of CMQL is better than that of cryogenic technology or MQL alone. Finally, the prospect, which provides basis and support for engineering application and development of CMQL technology, is introduced considering the limitations of CMQL.

“…TC4 and TiB2 powders were mixed at a certain ratio and TiBw/ TC4 composites were prepared by high temperature hot pressing sintering. 22 The detailed chemical components of TC4 are listed in Table .1. Tensile testing of the prepared TiBw/TC4 composite, as well as the TC4 alloy alone, was performed and the stress-strain curves are shown in Figure 1.…”

TiBw / TC4 composite material was used as the machining object of Ultrasonic vibration assisted drilling (UVAD), the single directional three-degree-of-freedom dynamical system model was established. The dynamic signal test and analysis system was used for modal experiment to identify the parameters in the model. Under the condition of dry cutting, the drilling axial force and tool vibration in the drilling process are studied. The results showed that the maximum values of the predicted and measured axial drilling force were 412.5N and 439.6N respectively, and the error rate was 6.165%, which verified the reliability of the predicted axial drilling force model. For cutting tools, the average amplitudes of simulated vibration and measured vibration were 0.1124mm and 0.1151mm respectively, with a difference of 2.402%, and the overall trends were the same, which verifies the reliability of the dynamical model. Finally, the stability of drilling process was analyzed, and the frequency and amplitude of ultrasonic vibration were analyzed. The results show that in order to expand the unconditional stability region, it is more efficient to increase the amplitude than to increase the frequency.

“…TiBw/TC4 titanium matrix composites are one of the most crucial groups of metal materials for aviation, aerospace, and automobile industries, benefit from their high specific stiffness, high specific strength, excellent mechanical properties at high temperatures, and wear resistance [1]. However, 70 % of fatigue failures of composite components are caused by defects in hole-making which contain cracks, burrs, scratches and other defects for the anisotropy of TiBw/TC4 composites [2], and it is also accompanied by drastic wear of the tool which affects the performances, production costs and the wide application of composite components [3].…”

With the gradual promotion and the application of difficult-to-machine materials such as titanium matrix composites in the aerospace field, high-quality hole-making technology has become a major demand in aviation manufacturing. In order to improve the hole-making quality of TiBw/TC4 composites, asynchronous mixed frequency vibration assisted hole-making (AMFVAHM) method is proposed. The process consists of two steps which are base hole drilling assisted with ultrasonic vibration (UVAD) and hole expansion by helical milling assisted with low-frequency torsional vibration (LFTVAHM). Based on this process, the cutting trajectory modeling is established, and the hole-making experiment on TiBw/TC4 composites is conducted. The experimental data shows that the maximum XY-plane average milling force decreases by 30.96 % and the maximum axial average milling force decreases by 24.49 % compared with conventional helical milling (HM) when the torsional vibration frequency and the milling frequency are the same in LFTVAHM. The hole-making experiment shows that AMFVAHM can reduce the chip size, tool wear and some other defects such as entrance/exit burrs, scratches and fractures of the hole wall. Comparing with HM and UVAD, the verticality of hole wall increases by 71.43 % and 86.21 %, the inlet damage decreases by 27.98 % and 31.60 %, the outlet damage decreases by 2.80 % and 14.47 %, the hole wall roughness (Ra) decreases by 36.29 % and 63.43 %, and the maximum white layer thickness decreases by 19.99 % and 67.66 %. Meanwhile, AMFVAHM process not only reduces the cutting force and cutting temperature, but also improves the hole-making quality due to the fretting friction effect of LFTVAHM in secondary hole expansion, which meets the need of high-quality hole-making of difficult-to-machine materials in practical engineering applications.
