摘　　要：针对YG8和TiAlN涂层硬质合金两种刀具,通过单因素车削、低速铣削及正交高速铣削加工试验,探究刀具切削工艺参数对TC4-DT钛合金加工件表面粗糙度、表层硬度的影响规律。实验结果表明:钛合金的表面粗糙度随着切削三要素发生变化,切削速度越高,粗糙度越低;进给量越大,粗糙度越大;但随切削深度波动变化。使用TiAlN涂层硬质合金立铣刀进行加工得到的平均表面粗糙度小于YG8硬质合金立铣刀,且加工表面硬度变化更小,更适合用于TC4-DT的铣削加工。The effects of cutting process parameters of YG8 and TiAlN coated cemented carbide tools on the surface roughness and surface hardness of TC4-DT titanium alloy were studied by single factor turning, low speed milling and orthogonal high speed milling experiments. The experimental results show that the surface roughness of titanium alloy changes with the three elements of cutting. The higher the cutting speed, the lower the roughness. The larger the feed, the greater the roughness;however, it fluctuates with the cutting depth. The average surface roughness obtained by using TiAlN coated cemented carbide end mill is smaller than that of YG8 cemented carbide end mill, and the hardness of the machined surface changes less, which is more suitable for milling TC4-DT titanium alloy.
