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: Titanium alloy and nickel-based high-temperature alloy have exceptional mechanical properties and are extensively used in aero-engine blades. However, their poor machinability is due to high material strength and low thermal conductivity, resulting in technical difficulties during the machining process. This study investigates the material properties and processing mechanisms of these alloys, focusing on recent advancements in cutting dynamics, chip formation mechanisms, tool wear, and surface integrity. The importance of rational setting of cutting parameters and machining conditions on machining integrity is discussed and future trends in high surface integrity machining of these alloys are predicted.

Summary: This paper introduces a workpiece discretization method to predict cutting forces during low material removal rate robotic machining, with specific models for operations along straight edges. The method involves measuring workpiece features using a high-resolution laser scanner, discretizing the features into rectangular sections for applying cutting force models. Linear and exponential mechanistic models relating tool immersion and feed rate to cutting force show good agreement with measured data, except for occasional over prediction by the linear model based on radial depth of cut.

Summary: This study clarifies the differences between the micro/nano incremental material removal mechanisms of conventional cutting (CC) and high-frequency ultrasonic vibration-assisted cutting (HFUVAC), and compares their machinability advantages and microstructure features through ultra-precision cutting experiments. The results indicate that HFUVAC achieves superior machinability by reducing cutting force, reducing tool wear, suppressing surface defects, and transitioning chips from a discontinuous quasi-shear state to a continuous multiple-shear state. The study provides guidance for improving surface quality and optimizing the cutting speed to vibration frequency ratio to enhance efficiency.
