“…To overcome this difficulty, researchers conducted a lot of attempts, including the optimization of grinding parameters [133], development of proper grinding fluid [134], and design of a binderless grinding wheel [135], and so on. Among them, the diamond grit's geometry considerably influences the quality of the machined surface [136].…”

Brittle materials are widely used for producing important components in the industry of optics, optoelectronics, and semiconductors. Ultraprecision machining of brittle materials with high surface quality and surface integrity helps improve the functional performance and lifespan of the components. According to their hardness, brittle materials can be roughly divided into hard-brittle and soft-brittle ones. Although there have been some literature reviews for ultraprecision machining of hard-brittle materials, up to date, very few review papers are available that focus on the processing of soft-brittle materials. Due to the “soft” and “brittle” properties, this group of materials has unique machining characteristics. This paper presents a comprehensive overview of recent advances in ultraprecision machining of soft-brittle materials. Critical aspects of machining mechanisms such as chip formation, surface topography, and subsurface damage for different machining methods, including diamond turning, micro end milling, ultraprecision grinding, and micro/nano burnishing, are compared in terms of tool-workpiece interaction. The effects of tool geometries on the machining characteristics of soft-brittle materials are systematically analyzed, and dominating factors are sorted out. Problems and challenges in the engineering applications are pointed out, and solutions/guidelines for future R&D are provided.

“…where L (𝐿 = 𝜑𝑟) was the distance between two adjacent cutting grains, 𝜑 was the angle between adjacent cutting edges in same ring, r was the radius of the ring where the cutting edge was located, vw was the working table speed (i.e., feed rate), and vs was the linear speed of the grinding wheel [21].…”

Laser processing has its advantages of high energy density, good controllability and high flexibility; it has shown its importance in advancing modern manufacturing. Laser processing is used in this paper to fabricate an end grinding wheel with orderly arranged abrasive particles, and the performance of the fabricated grinding wheel is compared with that of a conventional grinding wheel. Our experiment and comparative studies have drawn the conclusions of (1) active laser brazing has been successfully used to arrange diamond particles in Archimedes’ spirals; (2) the resulted grinding wheel has shown the enhanced effectiveness in comparison with the conventional grinding wheel in terms of reduced grinding force; when the spiral change rate i is set 0.25, the tangential grinding force has been reduced by up to 60%; (3) for a grinding wheel with specific spiral change rate, ground debris are discharged from the grinding zone in a certain direction, and the grinding temperature can be reduced; (4) in high-speed grinding, the surface quality by the grinding wheel with orderly arranged abrasive particles is better than that of conventional grinding wheel; under the tested grinding conditions, the roughness of the ground surface has been reduced up to 47% of that by conventional grinding wheels; (5) the grinding wheel with orderly arranged abrasive particles has shown the better wear-resistance that conventional grinding wheels; abrasive particles of all four conventional grinding wheels are damaged to certain extent but orderly arranged abrasive particles on the fabricated wheel maintain mostly their protruded heights.
