摘　　要：绿色制造技术是当今制造业的发展潮流,迎合了可持续发展理念的发展要求。金属刀具切削加工也朝着绿色、无污染、高效、低耗、节能的绿色干切削加工方向发展。基于该理念,介观几何特征刀具概念被提出。介观几何特征(刃口、微织构)是介于宏观和微观尺度的微小特征。刀具表面置入微织构可以减小刀-屑接触长度、捕获磨粒和切屑等杂质,从而改善刀具切削性能、提高工件表面质量;刀具刃口处理同样可以提高刀具耐磨性、改善切削状态及已加工表面质量。研究发现,介观几何特征对加工过程中力-热特性、工件表面质量以及刀具寿命等产生重要影响。因此,总结归纳了介观几何特征对刀具各方面切削性能影响的研究现状,探讨介观几何特征对刀具综合切削性能的影响规律,并为后续介观几何特征刀具的优化设计及制备提供参考。Green manufacturing technology is the development trend of today's manufacturing industry,catering to the development requirements of sustainable development concepts.Metal cutting tools are also developing towards green,pollution-free,efficient,low consumption,and energy-saving green dry cutting.Based on this concept,the concept of mesoscopic geometric feature cutting tools has been proposed.Mesoscopic geometric features(cutting edge,micro texture)are tiny features are tiny features between the macro and micro scales.The micro-texture on the tool surface can reduce the tool-chip contact length,capture abrasive particles and chips and other impurities,thereby improving the cutting performance of the tool and the surface quality of the workpiece.The treatment of the cutting edge can also improve the wear resistance of the cutting tool,improve the cutting state,and improve the quality of the machined surface.Research has found that mesoscopic geometric features have a significant impact on the force thermal characteristics,workpiece surface quality,and tool life during the machining process.Therefore,the current research status of the influence of mesoscopic geometric features on various aspects of cutting performance of cutting tools has been summarized,and the influence law of mesoscopic geometric features on the comprehensive cutting performance of cutting tools has been explored,providing reference for the optimization design and preparation of mesoscopic geometric feature cutting tools in the future.
