Abstract The high-speed cutting-tool system is the pivotal components of a com puter numerical control last carving machine，whose performance directly influences the manufacturing quality of shoe last．A 3D solid model of a high-speed cutting-tool system is established and a dynamic analysis finite element model is developed．Furthermore，the normal modes of cutting-tool are calculated，whose results highly accord with those gained in experimental test．Based on such dynamic FEM analysis model，loads of cutting-tool when machining are analyzed，and dynamic velocity and displacement(on outer-surface of cutting-tool)response are calculated．These are significant for further analysis and research on noise of cutting-tool．

高速切削刀具系统固有特性和动态响应分析
高速切削刀具系统是数控刻楦机主要部件，其性能的优劣直接影响到鞋楦的加工质量．构造了高速切削刀具系统的三维实体模型，建立了系统动力分析有限元模型，计算了高速切削刀具系统的固有模态，与测试结果符合较好，基于该动力分析有限元模型，分析了加工状态下刀具承受的切削力激励载荷，计算得到刀具表面的速度和位移响应，对高速刀具进行进一步噪声分析研究具有重要的意义。
