This comprehensive introduction to ultraprecision machining and metrology provides an essential foundation for students and engineers, offering an in-depth analysis of key methods, technologies, and practical applications. Ultraprecision machining is a critical enabling technology for producing high-value mechanical, optical, optoelectronic, and biomedical components with complex geometries and extreme precision. This book delivers a structured exploration of ultraprecision machining and metrology, covering essential topics such as system configuration, tooling, machining mechanism modeling, and surface characterization. Dedicated chapters on surface and subsurface metrology, as well as the machinability of both ductile and brittle materials, make it an indispensable resource for understanding machine design, manufacturing processes, and related materials science. Ideal for students and researchers, this book serves as a vital reference for those working in precision machining, MEMS, advanced manufacturing, and precision metrology.

In this chapter, firstly, a comprehensive review of electrical discharge coating (EDC) was made to identify a new research area, then the EDC technique with quarry dust powder suspension on tungsten carbide cobalt was introduced. The effects of quarry dust suspension on the coated surface characteristics and tribological properties were investigated. By using EDC with quarry dust suspension, a layer of coating consisting of hard carbides (SiC, Mg2C3, Fe2C, and CaC2) and oxide phases (SiO2, Al2O3, Fe2O3, CaO, CoO, and ZnO) due to material migration was confirmed, and the coating layer thickness was greatly influenced by quarry dust concentration. Under coating conditions of 5 A of peak current (I p ) and 300 μs of pulse on time (T on ), the Vickers microhardness increased by 28%, while the surface roughness, coefficient of friction, and wear scar depth of the coating layer decreased by 29%, 61%, and 63%, respectively, when compared with the original substrate.

Fabricating microgrooves on part surfaces is a way to provide advanced functionality of the parts, which has recently increased in several fields, such as biotechnology, optics, and aerospace. Considerable progress has been achieved in groove-cutting technology with the equipment development, process optimization and mechanisms understanding. This chapter reviews the ultraprecision cutting technologies for manufacturing of microgrooves and microgroove-based microstructures on various materials. Major cutting methods and their principles/mechanisms for microgrooving have been introduced. The main challenges in the cutting of microgrooves on ductile materials and brittle materials, respectively, are pointed out. Some innovations in groove-cutting technology are also highlighted. Several aspects in demand for further research and development are provided.
