Summary: This article investigates the failure mechanisms observed during the fracture cutting of age-varying bovine cortical bone based on characteristic microstructures. Orthogonal cutting experiments are conducted on different age groups of bovine bones, showing key differences in microstructural constituents. High-speed camera images reveal six dominant microstructure-specific failure mechanisms. The cutting responses are sensitive to age-related microstructural variations and the tool rake angle.

Summary: The study reveals that damage induced by bone cutting extends beyond the necrotic region, with high cutting temperatures causing lower modulus, strength, and brittle behavior near the machined surface. In contrast, the bulk bone retains pristine properties and ductile behavior. This shows that drilling thermo-mechanical effects can impact bone both biologically and micromechanically, revealing previously neglected bone damage.

Summary: This paper presents the development of a microstructure-based finite element model for simulating fracture cutting of bovine cortical bone. A cohesive zone-based approach is used to simulate fracture cutting of different bone components. The novelty of this work lies in the heuristic extraction of cohesive zone parameters based on specific acoustic emission signatures, ensuring a capture of the observed failures. The validated model demonstrates the utility in tool design through parametric studies.

Summary: This study investigated the fabrication and performance of binderless nanostructured tungsten carbide (WC) cutting tools, utilizing the electroconsolidation method for powder sintering. The results showed that the pure WC nanostructure had advantages such as smaller cutting edge radius and higher quality machined surface compared to other materials. The durability of the binderless nWC inserts was significantly better than traditional WC-Co cutting tools, especially at elevated cutting speeds.

Summary: The machining of metal matrix composites (MMCs) presents challenges due to the mismatch of mechanical and thermal properties between the matrix and reinforced particles. This paper explores the effects of cutting regimes on surface integrity in MMC machining and identifies two different cutting mechanisms – semi-brittle and ductile cutting – based on feed rate/uncut chip thickness. The semi-brittle cutting regime leads to noticeable damaged surface morphology with a high density of fractured particles.

Summary: Mechanical processing of cortical bone tissue can improve surface morphology and properties, promoting tissue growth and drug release. The study found that orthogonal processing resulted in an increase in the surface topography parameter Ra from 1.38±0.17μm to 2.82±0.32μm, while no correlation was found between the orientation of osteons and topographical properties in abrasive processing. It is recommended to cut in the transverse direction and parallel to the axis of the osteons for optimal bone surface quality.

Summary: This study aims to understand how aging-related changes in cortical bone microstructure affect mechanical properties at the macroscale. By modeling cortical bone as a bundle of elastic-plastic fibers and simulating aging-related changes, the study found that changes to all three input parameters were needed to capture the decline in mechanical properties. Rupture of interstitial fibers led to initial strength loss, while plasticity and gradual rupture of osteons contributed to the remainder of the response.

Summary: This paper studies the chip formation mechanism of cryogenic machining and establishes a specific cutting energy model based on liquid nitrogen orthogonal milling experiments. The results show that in cryogenic machining, adiabatic shear dominates the formation of serrated chips when the cutting speed is less than 200 m/min, and the cutting energy consumption is higher than that of dry cutting. As the cutting speed exceeds 200 m/min, adiabatic shear and periodic fracture together dominate the formation of serrated chips, and the energy consumption of cutting is significantly reduced. This research provides reference and guidance for the sustainable development of cryogenic machining.

Summary: Bone machining research is often conducted without considering the influence of internal irrigation, which is crucial for realistically simulating surgical scenarios. This study proposes a new machining and pumping setup to better mimic bone machining under surgical conditions. Results show that internal irrigation can significantly affect the properties and cutting mechanism of bone, resulting in lower cutting forces and necrosis. Additionally, internal irrigation can alter chip formation and minimize surface damage.
