Abstract Hierarchical micro/nanograting structures have attracted increasing attention owing to their significant applications in the fields of structural coloring, anti-counterfeiting, and decoration. Thus, fabrication hierarchical is important for these applications. In this study, a strategy machining developed by controlling tool movement trajectory. A coupling Euler-Lagrange finite element model established simulate process. The effect methods on nanograting formation demonstrated, suitable method reducing cutting force obtained. height decreases with an increase edge radius. Furthermore, optical variable devices (OVDs) are machined using array overlap approach. Coding schemes parallel column unit crossover groove designed achieve high-quality OVDs. coloring logo Harbin Institute Technology centennial anniversary surface metal samples, such as aluminum alloys, realized. findings study provide that can be used prepare

Abstract Strict requirements on the surface qualities of cemented carbide have been raised in manufacturing functional components and glass molding. However, high hardness increases difficulty improving qualities. The application ductile‐regime machining theory to improve quality is unsatisfactory because severe tool wear, varying factors microstructure defects induced by stress. To illustrate complex mechanism removal carbide, firstly, for are introduced. Secondly, methods evaluating mechanical properties discussed terms microstructures. Thirdly, conflicts between traditional analyzed, leading proposed limitations solutions applying composite materials. In addition, developments ultra‐hard tools energy field‐assisted techniques applied summarized discussed. Finally, technical challenges future this field further pointed out.

Black phosphorus (BP) stands out among vdW materials for chemical sensing, with its edge sites offering the potential to enhance performance. While nanocutting method shows promise BP fabrication, underlying mechanism remains unclear, lacking guidance process. In this study, molecular dynamics (MD) simulations were conducted investigate material removal behavior during of while considering influence cutting thickness, tool radius, and angle. These findings indicate that plastic is primarily governed by interlayer slip when using a relatively large rake contrast, at small angle, brittle state occurs due formation expansion shear band spanning across layers, leading crack propagation. Additionally, as thickness approaches "size effect" observed in BP. This phenomenon results both decreased deformation singular decrease force, ultimately causing an increase chip deviation. The research offer comprehensive theoretical foundation serve technical reference fabrication nanostructures sensing via nanocutting.
