“…Compared with tungsten carbide materials, the Ni−P plating can not only reduce the hardness of the mold materials, which can reduce tool wear and improve the service life of the materials, but also enhance the quality of the machined surface due to its superior uniformity, smoothness, and compactness. 44 According to the wedge structure illustrated in Figure 10, the parameter α represents the angle between the vertical surface and the sloping surface of the wedge structure, which is determined by the knifepoint angle of the diamond tool. The parameter w represents the width of a single biomimetic structure, as well as the interval between the biomimetic structures.…”

“…In the present study, tungsten carbide with a Ni–P plating with a thickness of 600 μm was used as the mold material. Compared with tungsten carbide materials, the Ni–P plating can not only reduce the hardness of the mold materials, which can reduce tool wear and improve the service life of the materials, but also enhance the quality of the machined surface due to its superior uniformity, smoothness, and compactness …”

The current research on gecko-inspired dry adhesives is focused on micropillar arrays with different terminal shapes, such as flat, spherical, mushroom, and spatula tips. The corresponding processing methods are mostly chemical methods, including lithography, etching, and deposition, which not only are complex, expensive, and environmentally unfriendly, but also cannot completely ensure microstructural integrity or performance stability. The present study demonstrates a high-precision, high-efficiency, and green method for the fabrication of a gecko-inspired surface, which can promote its application in dexterous robot hands and mechanical grippers. Based on the bendable lamellar structures of the gecko, annular wedge adhesive surfaces that stick to the finger surfaces of dexterous robot hands to improve their load capacity are proposed and fabricated via a suitable combined processing method of ultraprecision machining and replica molding. The greater the width, the higher the replication integrity, and when the minimum width is 20 μm, the replication error is less than 5.5% due to the superior processing performance of the nickel–phosphorus (Ni–P) plating of the master mold. The fabricated annular wedge structures with an optimized width of 20 μm not only exhibit a strong friction force of up to 35.48 mN under a preload of 20 mN in the GCr15/poly(dimethylsiloxane) (PDMS) friction pair but also demonstrate an obviously improved anisotropic friction characteristic of up to λ = 1.36, as the molecular force exhibits a stronger increase as compared to the decrease of the mechanical force of the structure with a small width.

“…To fabricate smaller microstructures with more complicated shapes on molds, the microdiamond wheel has been proposed and utilized in microstructure surface machining. Aurich et al proposed the concept superabrasive electroplated grinding wheels based on defined grain structures [168,169]. Because the strength and impact resistance of a grinding wheel are mainly determined by the bonding agent, metal bonds are predominantly employed in the fabrication of superabrasive grinding wheels due to their excellent formability and high strength compared to resin bonds and vitrified bonds [168,170].…”

“…The electro-plating method has been widely used to fabricate micro-grinding wheels due to its low cost. Onikura et al conducted the fabrication of micro-cylindrical diamond grinding wheels with diameters from 100 to 500 µm via the electroplating of diamond grits in a Watts bath [168,171], and the fabricated microdiamond wheel was then utilized to fabricate grooves on Tungsten carbide (WC) and cemented carbide [172], as shown in figure 34.…”

Micro/nanostructured components play an important role in micro-optics and optical engineering, tribology and surface engineering, and biological and biomedical engineering, among other fields. Precision glass molding technology is the most efficient method of manufacturing micro/nanostructured glass components, the premise of which is meld manufacturing with complementary micro/nanostructures. Numerous mold manufacturing methods have been developed to fabricate extremely small and high-quality micro/nanostructures to satisfy the demands of functional micro/nanostructured glass components for various applications. Moreover, the service performance of the mold should also be carefully considered. This paper reviews a variety of technologies for manufacturing micro/nanostructured molds. The authors begin with an introduction of the extreme requirements of mold materials. The following section provides a detailed survey of the existing micro/nanostructured mold manufacturing techniques and their corresponding mold materials, including nonmechanical and mechanical methods. This paper concludes with a detailed discussion of the authors recent research on nickel-phosphorus (Ni-P) mold manufacturing and its service performance.
