【摘要】：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。
[Abstract]:The main processing methods of high speed cutting and difficult processing materials, in the cutting process, the fast tool wear machining problems such as poor surface quality significantly. In recent years, due to surface texture in the control of friction, reduce wear and improve the lubrication performance and other aspects of the role has aroused wide interest in academia and industry. To reduce friction, tool grinding technology provides a new research direction. The effect is through the surface texture on the friction surfaces processed with different shapes and geometrical parameters of micro pits distribution characteristics, such as micro channel array structure, thermal mechanical effect of friction wear and lubrication characteristics change. According to the study on Application of surface texture in the tool, describes the main surface texture tool preparation method, comparative analysis of the advantages and disadvantages of various preparation methods, and elaborates the micro groove texture, Micro concave texture, texture of nano / micro nano composite structure array and textured self-lubricating tool in reducing tool wear, research status and progress of improving machining quality and other aspects, and analyzes the causes and mechanism of surface texture to improve tribological properties of tool system, finally pointed out the significance of tool surface texture technology, the problem of current research and reduce friction wear of the tool.
