摘　　要：TB6钛合金高速铣削以高效率、高质量的优点广泛应用于航空航天行业。面向高速铣削中表面粗糙度的工艺控制,通过高速端面铣削正交试验,研究并分析了高速铣削参数对表面粗糙度及三维表面形貌的影响。研究表明:表面粗糙度对每齿进给量变化最为敏感,对铣削速度变化敏感次之,对铣削宽度的变化最不敏感;铣削速度优选范围为100～140m/min,每齿进给量优选范围为0.04～0.08mm/z,可保障表面粗糙度在0.7μm内;铣削速度和每齿进给量配比组合影响表面形貌的形成。High-speed milling of titanium alloy TB6 is widely used in aviation and aerospace industries for its high efficiency and good quality. For controlling the process of surface roughness in high-speed milling, the experiments of high-speed end milling is done to investigate the effect of milling parameters on surface roughness and 3D surface topography. The results show that surface roughness of high-speed milling for titanium alloy TB6 is most sensitive to the variation of feed per tooth, next sensitive to the milling speed and it is the least sensitive to milling width. The optimum milling speed ranges from 100m/min to 140m/min, and the optimum feed per tooth ranges from 0.04mm/z to 0.08mm/z, the optimum cutting parameters can control the surface roughness below the value of 0.7μm. The surface topography is influenced by the combination proportion of milling speed and feed per tooth.
