摘　　要：为保证机床的精度满足微细铣削加工实验的要求,必须校验机床整机设计能否满足设计要求。在Pro/ENGINEER软件平台上,根据微型铣床各部件实际结构、尺寸和组成特点建立整机装配几何模型。通过理论、实验及有限元仿真相结合的分析方法,利用ANSYS有限元分析软件对所设计的立式微型数控铣床整机进行了静力学分析和动态特性分析,对整机在结构设计上能否满足加工精度设计要求进行了校验,并对今后机床整机设计提出新的方法。The overall structual design of machine tool should be verified to ensure the accuracy of the machine tool meeting the requirements of micro-milling machining. Using the Pro/E software the assembly geometric model of a vertical CNC micro-milling machine tool is established according to the corresponding components＇ actual structure, sizes and the composition characteristics. Based on the theoretical, experimental and finite element simulation analysis method, the static analysis and the dynamic characteristic analysis of the designed vertical CNC micro-milling machine tool are conducted using the ANSYS software, the overall structual design of the micro-milling machine tool is analyzed to check whether it meets the requirements of the micromilling machining, and a novel method for the overall structual design of machine tool is proposed too.
