摘　　要：介绍了五轴数控机床的运动方式,阐述了空间自由曲面五轴联动数控加工中刀具路径规划的基本方法:参数线法、CC路径截面线法、CL路径截面线法、导动面法等。之后对五轴加工中刀具轴向规划进行了论述:垂直于表面方式、平行于表面方式、倾斜于表面方式。最后归纳总结了刀具干涉的检测与处理的方法,并分别说明了其优缺点和适应范围。Mode of motion of the 5-axis numerical control machine tools is introduced.Then the basic methods of tool path planning in 5-axis numerical control machining of space free-form surfaces are ex-pounded,which include parametric method,cutter contact point path and cross-section method,cutter loca-tion point path and cross-section method,guiding surface method.After that,the tool axial orientation is pro-posed,it can be normal to the machining surface,parallel to the machining surface,or inclined to the ma-chining surface.At the end,the cutter interference checking and avoiding methods are summarized,in which the advantages,disadvantages and application limitation of each method are discussed.
