Abstract: Cutting tools are known as the “productivity” of the manufacturing industry, which affects the production efficiency and quality of the workpiece, and has become the focus of research and attention in academia and industry. However, traditional cutting tools often suffer from adhesion or wear during the cutting process, which considerably reduces the cutting efficiency and service life of the tools, and makes it difficult to meet current production requirements. To solve the above problems, scholars have introduced bionics into the tool’s design, applying the microscopic structure of the biological surface to the tool surface to alleviate the tool’s failure. This paper mainly summarizes the research progress of bionic textured cutting tools. Firstly, categorize whether the bionic texture design is inspired by a single organism or multiple organisms. Secondly, it is discussed that the non-smooth surface of the biological surface has five characteristics: hydrophilic lubricity, wear resistance, drag reduction and hydrophobicity, anti-adhesion, and arrangement, and the non-smooth structure of these different characteristics are applied to the surface of the tool is designed with bionic texture. Furtherly, the cutting performance of bionic textured cutting tools is discussed. The anti-friction and wear-resisting mechanism of bionic textured cutting tools is analyzed. Finally, some pending problems and perspectives have been proposed to provide new inspirations for the design of bionic textured cutting tools.
