| 高速切削加工作为难加工材料的主要加工方式，在其切削过程中，刀具的快速磨损、加工表面质量差等问题显著。近些年来，表面织构由于在控制摩擦、减小磨损和改善润滑性能等方面的作用引起了国内外学术界和产业界的广泛兴趣，为刀具减摩降磨技术的研究提供了新方向。表面织构效应是通过在摩擦副表面加工出具有不同形状几何参数和分布特征的微凹坑、微沟槽等阵列结构时，表面的摩擦磨损和润滑特性随之改变的热动力学效应。针对表面织构技术在刀具方面的应用研究，描述了刀具表面织构的主要制备方法，对比分析了各种制备方法的优缺点，然后分别阐述了微沟槽织构、微凹坑织构、纳米织构/微纳复合结构阵列以及织构化自润滑刀具在减缓刀具磨损、提高加工质量等方面的研究现状与进展，同时分析了表面织构改善刀具系统摩擦学性能的原因和机理，最后指出刀具表面织构技术目前研究存在的问题及其对刀具减摩降磨的重要意义。 |

| Tool wear and poor surface quality are the remarkable problems in high speed machining, which is the primary processing method for materials difficult to machine. In recent years, surface texturing technologies have attracted a great deal of attention owing to the function of friction control, wear reduction and lubrication improvement. It also provides a new direction for the research on technology to reduce the tool wear. Surface texture effect should be thermodynamics effect of which frictional wear and lubrication property will vary with micro-grooves and micro-dimples machined on the friction surface with diverse geometric shape parameters and distribution characteristics. Focusing on the surface texture technology applied on the tool, this paper firstly described the fabricating methods of tool texture, and compared the advantages and disadvantages of all methods. It then elaborated the development and perspective of this technique used in tool wear reduction and processing quality improvement from the aspects of micro-grooves, micro-dimples, micro/nano hybrid textures and textured self-lubricating tools. In addition, the reason and mechanism of improving the tribological properties were analyzed for tool system. Finally, the problems with the research on tool surface texture technology and its importance to tool wear reduction were pointed out. |
