Summary: This research investigates the potential application of ultrasound-assisted drilling in reducing friction force and improving drilling efficiency through theoretical analysis and experimental tests. The results show a significant reduction in the coefficient of friction on silicon wafers and in machining forces during ultrasonic-assisted milling. Additionally, experiments on drilling rock samples demonstrate a substantial decrease in drilling force with the use of ultrasound-assisted vibrations.

Summary: This study proposes an ultrasonic longitudinal torsion-assisted drilling (ULTAD) technique for biotic bone drilling. A comparative experiment between conventional drilling and ULTAD drilling in porcine femur showed that the ultrasonic component in bone drilling can reduce temperature and forces, improve material removal and chip breaking, shorten bone debris length, and facilitate discharge. Moreover, ULTAD technique reduces microcracks in the borehole wall, protecting the drilled biotic bone from internal damage.

Summary: The use of ultrasonic-assisted high-speed drilling has been proven effective in improving the height of the exit burr on titanium alloy micro-holes. Analyzing the height of the exit burr and its modeling development provide insight into the effects of processing parameters on burr height. Experimental results and analytical modeling show a negative correlation between exit burr height and ultrasonic amplitude and spindle speed, and a positive correlation with feed speed, with larger amplitude, spindle speed, and smaller feed speed being beneficial for higher shape accuracy in micro-holes exit morphology.

Summary: Micro-hole is widely used in various fields, and the common machining methods in factories, which are drilling and electrical discharge machining (EDM), cannot meet the requirements due to their low efficiency. Therefore, this paper investigates an efficient micro-hole machining technology by combining ultrasonic machining with micro-fine small hole drilling. The results show that ultrasonic vibration-assisted drilling (UAD) has comparable performance to conventional drilling in machining micro-holes below 0.5 mm, with stable machining diameter, good shape tolerance, small cutting force, tool wear, and surface roughness of inner wall. Compared to EDM, UAD has higher efficiency and better stability in terms of diameter and shape tolerance. It is concluded that UAD can be used as an alternative technology for machining small holes in non-special requirements of metal materials in factories with technical feasibility for stable batch production.

Summary: In this study, a mathematical prediction model considering the ultrasonic vibration of the drill is established to calculate the thrust force of ultrasonic vibration-assisted drilling (UVAD). A 3D finite element model (FEM) for the thrust force and chip morphology analysis is subsequently researched based on ABAQUS software. The results show that UVAD can effectively reduce the thrust force and improve chip evacuation compared with conventional drilling (CD).

Summary: In this study, a force model was developed for ultrasonic vibration-assisted drilling of SiCf/SiC ceramic matrix composites, taking into account the trajectory of the drilling tool, the tool-workpiece contact state, and the material removal mode. The coefficients of abrasive grains, crack growth parameters, and difficult-to-measure mechanical parameters were determined through coefficient calibration experiment and the least square method. The drilling and vibration parameters were merged to build the analytical force model, and the influence of parameters on the force was studied. The suggested force model showed good agreement with experimental results, with a maximum relative error of 17.34%.

Summary: Ultrasonic-assisted drilling (UAD) is an efficient method to improve the drillability of difficult-to-cut materials. In this study, UAD of Inconel 718 was investigated under different cooling and/or lubrication conditions. The test results showed that UAD reduced thrust force, improved hole quality, tool life, and surface integrity. The simultaneous application of cutting fluid and minimum quantity lubrication (MQL) had better performance for UAD.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: The existing methods for predicting hip and lumbosacral joint centres in Japanese adults are biased and differ between sexes. We propose new regression equations that consider soft-tissue thickness, sex differences, and a height-directional measure, and validate them using leave-one-out cross-validation.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
