摘　　要：在对金属材料进行切削加工过程中,刀具刃口部分的宏观和微观几何结构对提高工件加工精度、提升切削效率以及完善延长刀具寿命等方面都起着重要的作用。现代数控车刀相对于传统刀具,基本是以可转位刀片为主体的可拆卸结构,在设计可转位车刀时,应对被加工件的材料属性、切削技术条件以及工件几何精度等因素进行统筹考虑,在刀片的宏观和微观结构以及刀杆本身几何外形两方面进行综合分析,从而为高性能数控刀具的结构设计奠定基础。通过对现代数控可转位刀片及刀杆几何结构进行综合研究分析,提出了高性能可转位刀具结构的工程设计方法,可为现代数控刀具的创新设计提供新的思路。In the process of cutting metal materials,the macro and micro geometric structure of the cutting edge played an important role in improving the machining accuracy,cutting efficiency and tool life.Compared with the traditional tools,the modern NC turning tool was a detachable structure with indexable blade as main body,when designing indexable blade,it was necessary to consider the material property,cutting technology condition geometric accuracy of work piece and so on.I comprehensively analyzed the macro and micro structure and geometric profile of tool bar,so as to lay the foundation for improving structure design of high-powered NC tools.Through the comprehensive research and analysis of the geometric structure of modern NC indexable blade and tool bar,it was presented that the engineering design method of high-performance indexable tool structure,which provided a new idea for the innovative design of modern NC tools.
