“…It has been demonstrated that UVG can reduce the surface roughness of the workpiece and improve the surface quality during microstructure manufacturing [175]. It can also reduce the grinding force [176] and further improve the stability of the cutting system. UVG can reduce grinding wheel blockage, effectively maintain the sharpness of the abrasive grains, improve the cutting performance of the grinding wheel, reduce grinding wheel wear, and improve grinding efficiency.…”

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.

SiC ceramics have excellent comprehensive properties and are typical hard and brittle materials that are difficult to process and are widely used in many fields. Laser polishing technology has developed into a new surface processing technology, and femtosecond laser polishing has become an important method for the precision machining of hard and brittle materials. In this paper, SiC ceramics were ablated and polished by infrared femtosecond laser, the laser ablation threshold of SiC ceramics was calculated and the influence of pulse energy and defocus amount on the surface morphology, surface roughness, polishing depth and oxidation degree of femtosecond laser polishing of SiC ceramics were investigated. The results show that when the laser repetition frequency f = 175 kHz, wavelength λ = 1064 nm and ablation time t = 9 s, the laser ablation threshold of SiC ceramics is 0.355 J/cm2. With the increase in pulse energy, the surface roughness first decreased and then increased, and the polishing depth showed an overall upward trend. The change of defocus amount will lead to the change of the laser spot diameter. With the increase of the defocus amount, the laser spot irradiated on the workpiece surface becomes larger, and the laser energy density decreases, which results in the decrease of the laser ablation ability and polishing depth and the increase of the polished surface roughness. Periodic nano-ripple structures appeared on the laser-induced surface. Through Energy Dispersive Spectrometer (EDS) elemental analysis, it was found that there was an oxidation phenomenon in SiC ceramics polished by femtosecond laser in an air environment, and the change of pulse energy and defocus amount had insignificant effects on the degree of oxidation.

“…The tool wear can be reduced and the surface roughness can be improved by applying ultrasonic vibration in grinding [7]. Based on the dynamic analysis of single abrasive grinding of zirconia ceramics, Chen et al [8] established a three-dimensional grinding force model for ultrasonic-assisted ELID grinding. The three-dimensional ultrasonic vibration makes the abrasive grain cutting trajectory longer, and the surface roughness is improved during grinding.…”

SiCp/Al is a kind of particle reinforced composites with good material properties, which can be used in the field of lightweight parts and electronic packaging. Ultrasonic- assisted grinding process is one of the processes which is suitable for machining hard and brittle materials, the surface quality can be improved by using appropriate ultrasonic-assisted process parameters. In this paper, the ultrasonic-assisted grinding process is used to improve the surface quality of SiCp/Al, meanwhile, the kinematics of abrasive particles in grinding is analysed to explain the effect of ultrasonic vibration. In addition, ultrasonic-assisted grinding experiment of SiCp/Al is conducted, it is found that the axial ultrasonic vibration can improve the surface quality of SiCp/Al in grinding, and the reduction percentage is up to 8.20% compared to the normal grinding. In addition, a regression model is proposed for surface roughness prediction, the result of t-test on the residuals shows that the model is accurate.
