A comprehensive review of advances in design of micro-texture on tool surface and its cutting performance.

By producing micro-textures with different geometric parameters on the tool surface, the cutting performance of the tool can be effectively improved. Scientists have carried out the design and development of microstructures on the surface of tools based on the study of the performance of microstructured tools. Based on this, this theory first summarizes the production methods of surface microstructures, which are divided into photothermal energy composite processing, electrothermal energy composite processing, and mechanical energy processing according to the different energies. The effects of microtexturing on tool wear, tool strength, and tool life are then examined. Then, the geometric design of surface microtexturing tools from simple texturing to heterogeneous texturing is reviewed, and the mechanism of microtexturing tools is analyzed. Finally, the development direction of tools with surface micro-texture is given to provide guidance for the optimized design of the micro-texture of tool surfaces. [ABSTRACT FROM AUTHOR]
