“…On the other hand, FeAlbinding diamond tools showed a higher grinding rate than NiAlbinding diamond tools due to enhanced self-sharpening ability. It has been confirmed that both NiAl and FeAl-based diamond wheels can be effectively used to grind silicon nitride ceramics [11]. The loading phenomenon in grinding process increases grinding resistance and interferes with the protrusion of grinding particles to induce brittle destruction of ceramic materials, which is the main cause of deterioration of the ground surface and chipping.…”

As advanced technology develops, high-functional ceramics are attracting attention as high-performance parts materials due to their excellent physical properties such as high strength, heat resistance, wear resistance, functional surface, and corrosion resistance. However, ceramics are brittle materials and are very difficult to machining, so there are many restrictions on making shapes by machining. Therefore, in order to meet the demand for high-functional ceramics, ultra-precision machining and high-efficiency machining technologies are required. Silicon nitride ceramics are highly regarded as functional precision parts, but the process of making parts with high reliability and precision is never easy due to their unique characteristics of ceramics, brittleness. This review focuses on the latest convergence research incorporating optimization technology as well as ceramic machining technology that induces ductile fracture and identification of the microstructure failure mechanism in relation to the trend of removal machining technology, focusing on silicon nitride ceramics. The development of ceramic removal machining technology is essential for all ceramic materials, not just silicon nitride ceramics, to be widely applicable as functional high-tech materials.

“…Early diamond tools were limited to machining soft and malleable non-ferrous metal materials, such as aluminum and copper [117]. At present, ultra-precision diamond cutting has been extended to silicon, steel, and other difficult-to-cut materials [23], which have special functions and meet the needs of optical, semiconductor, mold, and other industries [118][119][120]. However, rapid tool wear is still a problem to be solved.…”

Micro-structured surfaces possess excellent properties of friction, lubrication, drag reduction, antibacterial, and self-cleaning, which have been widely applied in optical, medical, national defense, aerospace fields, etc. Therefore, it is requisite to study the fabrication methods of micro-structures to improve the accuracy and enhance the performance of micro-structures. At present, there are plenty of studies focusing on the preparation of micro-structures; therefore, systematic review of the technologies and developing trend on the fabrication of micro-structures are needed. In present review, the fabrication methods of various micro-structures are compared and summarized. Specially, the characteristics and applications of ultra-precision machining (UPM) technology in the fabrication of micro-structures are mainly discussed. Additionally, the assistive technologies applied into UPM, such as fast tool servo (FTS) technology and slow tool servo (STS) technology to fabricate micro-structures with different characteristics are summarized. Finally, the principal characteristics and applications of fly cutting technology in manufacturing special micro-structures are presented. From the review, it is found that by combining different machining methods to prepare the base layer surface first and then fabricate the sublayer surface, the advantages of different machining technologies can be greatly exerted, which is of great significance for the preparation of multi-layer and multi-scale micro-structures. Furthermore, the combination of ultra-precision fly cutting and FTS/STS possess advantages in realizing complex micro-structures with high aspect ratio and high resolution. However, residual tool marks and material recovery are still the key factors affecting the form accuracy of machined micro-structures. This review provides advances in fabrication methods and assistive technologies of micro-structured surfaces, which serves as the guidance for both fabrication and application of multi-layer and multi-scale micro-structures.
