摘　　要：在分析高速面铣刀变形和振动对其综合切削性能影响的基础上,采用均匀试验设计方法,通过高转速条件下铣刀变形和固有特性数值分析,获得高速面铣刀最大变形与共振频率回归模型;采用彭恒武判别法建立高速面铣刀综合性能判据,并对典型结构高速面铣刀性能进行了综合评判。结果表明,弹性模量、密度等铣刀材料属性对其安全性和高效切削性能具有重要影响;采用铣刀综合性能判据,可有效地控制其变形和共振范围,获得良好的综合切削性能;采用上述评价方法设计的高速面铣刀切削高强度铝合金时,金属切除率达到129600mm3/min,表面粗糙度小于0.8μm,其综合性能满足高速切削要求。On the basis of analyzing the influence of the deformation and vibration of high-speed face milling cutter on the comprehensive cutting performance, applied homogeneous design method, the regression .an^ysis model of maximum deformation and resonance frequency of the high-speed face milling cutter was established by numerical analysis of deformation and inherent characteristic of milling cutter in high speed. Using PengHengwu discriminance the comprehensive performance criterion of the cut- ter was set up, and the comprehensive performance of the high-speed face milling cutter with typical structure was evaluated. The results showed that material properties of the cutter such as elastic modulus and density had important influence on security and cutting efficiency; using the comprehensive performance criterion could effectually control the deformation and resonance region of the cutter, and the favorable cutting performance could be got; when a high-speed face milling cutter designed by adopting above- mentioned evaluation methodology was used to cut high strength aluminum alloy, the metal removal rate could reach 129600mm3/min, and the surface roughness could be less than 0.8μm, the results could meet the needs of high-speed cutting.
