In recent years, the requirements for high-quality development in the manufacturing industry and extreme application conditions have increasingly demanded higher equipment performance. The surface and interface condition of components is directly related to the stability, reliability and service life of equipment. The development of high-performance or multi-performance surface texturing is of great significance for the effective improvement of mechanical properties, optical properties, catalytic properties and biological properties of surfaces. This paper summarizes the application of textured surfaces in improving the physical, chemical and biological properties of surfaces; outlines the types of texturing patterns and the design methods; analyzes the main technical methods and their characteristics for the preparation of surface textures in additive manufacturing, subtractive manufacturing and equal material manufacturing; and makes outlooks on texturing surfaces from the aspects of performance enhancement, pattern design and manufacturing technology in combination with the development trend of textured surfaces’ intelligence and digitization.

This study investigated the sawing of A-plane and C-plane sapphires using the reciprocating diamond wire saw. The influences of process parameters and sapphire crystal structure on sawing force were experimentally researched. The experimental results indicated that, in sapphire sawing process, the sapphire crystal structure, the wire speed, and the feed rate had effects on the tangential sawing forces, and the tangential forces had good linear relationships with the material removal rates (MRRs). The specific sawing energies in the stable stage were clearly smaller than in the unstable stage.

A diamond wire sawing process was developed for slicing granite in order to complement the disk sawing. Machining characteristics and tool wear during wire sawing of a granite material that consists of three major minerals, that is, quartz, feldspar and mica, were systematically investigated. The material removal mechanism involved in the sawing was explored. The scanning electron microscope examination of the sawn surfaces of the granite and the analysis of the force and temperature involved in the sawing process indicated that the material removal of the granite was dominated by brittle fracture. The typical cleaving and slipping behaviors of feldspar and mica associated with sawing resulted in unique morphologies on the sawn granite surfaces. The tool wear of the process was characterized by the nonuniform wear of diamond beads impregnated on the wire, with the fore end of the diamond beads experiencing greater wear than the rear part.
