Summary: This study investigated the cutting performance of Polytetrafluoroethylene (PTFE) using orthogonal cutting experiments. Chip formation, cutting force, and surface quality were used to evaluate the influence of cutting parameters on cutting performance. The results showed that cutting depth had the most significant effect on cutting force, while cutting speed had the most obvious effect on surface roughness. An empirical mathematical model was developed to predict cutting force and surface roughness with good accuracy. The study suggests that higher cutting speed with a small cutting depth is ideal for ensuring the cutting performance and machining quality of PTFE.

Summary: A novel elliptical vibration cutting (EVC) is introduced for bone cutting in this study to improve tissue removal and postoperative rehabilitation, increase efficiency and accuracy, and reduce operating force. The material removals of cortical bone and their cutting forces from EVC and conventional cutting (CC) were comprehensively recorded and analyzed using high-speed microscope imaging and the dynamometer, which showed significant improvements in chip morphology and average cutting force reduction in the EVC process. Additionally, it was discovered that the elliptical vibration of the cutting tool could promote fracture propagation along the shear direction. These findings have important theoretical and practical implications for the application of the innovative EVC process in osteotomy surgical procedures.

Summary: By conducting a single-diamond grinding test on SSiC, researchers were able to identify stages of purely ductile, primarily ductile, primarily brittle, and purely brittle behavior during the grinding process. The high density of dislocations and amorphization of SiC grains were found to be responsible for the plastic deformation of SSiC, with stress concentration at grain boundaries being the main mechanism for crack initiation.

Summary: In this study, the cutting characteristics of Zr57Cu20Al10Ni8Ti5 (at.%) bulk metallic glass (Zr57 BMG) were compared with industrial pure zirconium (Zr702) during high-speed machining (100-350 m/min). It was found that despite the higher strength of Zr57 BMG, there was no significant difference in the main cutting forces between the two materials, which was attributed to the thermal softening of Zr57 BMG during machining. Furthermore, the surface characteristics and chip morphology changed as the cutting speed increased, with the worst surface quality obtained at a speed of 250 m/min.

Summary: A gradient modified layer can be produced on the high-strength steel surface by carburizing heat treatment. Increasing the depth of the surface-modified layer leads to a decrease in yield strength and kernel average misorientation value, as well as an increase in equivalent grain size and the number of large-angle boundaries. Deformation occurs inside the martensitic packet, while the large-angle boundaries hinder the propagation of the fatigue crack.

Summary: The nonlinear interaction between longitudinal vibration and ultrasound in beams with cracks is studied. The focus is on the localized enhancement effect of this interaction, known as locally enhanced nonlinear vibro-acoustic modulation. Numerical and experimental investigations are conducted, exploring different crack models and considering various parameters such as crack depths, locations, and boundary conditions. The study reveals that strong nonlinearities, indicating nonlinear crack-wave modulations, occur near the crack, allowing for crack localization and differentiation from other sources of nonlinearity.

Summary: This study investigates the effect of wear of surgical drill bits on their performance. The surface quality of the drill was found to influence the bone temperature, the axial force, the torque and the extent of biological damage around the drilling region. A worn drill produced excessive heat, causing thermal necrosis comparable to the thickness of an adult human bone wall. Statistical analysis reveals that a sharp drill bit, medium drilling speed and shallow depth are favorable for safe drilling in bone. Further research is recommended to establish a relationship between surface integrity of a surgical drill bit and the irreversible damage it can induce in delicate bone tissues using different drill sizes and parameters.

Summary: Carbon/carbon composites are widely used in re-entry engineering applications due to their excellent mechanical properties, but they are prone to oxidation in the presence of oxygen. This study proposes a microscale degradation model to predict the oxidation behavior and evaluate the residual mechanical properties of the oxidized composite theoretically. A numerical strategy is used to investigate the oxidation mechanism and the results show a decrease in mechanical properties of the composite after oxidation. Stress redistribution and increased stress areas facilitate oxygen diffusion into the matrix and fibers.

Summary: In order to overcome the limited vibration performance of current vibration-assisted drilling (VAD) schemes for carbon-fiber-reinforced plastic (CFRP), a novel longitudinal-torsional complex-mode ultrasonic vibration-assisted actuator with single excitation and an elliptical locus is proposed. The actuator utilizes a piezoelectric transducer and a stepped horn with spiral grooves to deliver elliptical vibration and ensure high vibration performance of a tool tip. The actuation mechanism and design process of the actuator are discussed, and its vibration characteristics are verified through finite-element simulation and experimental modal analysis. It is demonstrated that the actuator achieves longitudinal-torsional elliptical vibration and improves the drilling performance of CFRP.
