摘　　要：钛合金Ti6Al4V的切削加工性很差,为实现其高效绿色切削,提出了用过热水蒸汽和电离空气作冷却润滑剂的绿色切削技术,分别在干切、乳化液、水蒸汽和电离空气条件下采用硬质合金铣刀YG6对Ti6Al4V进行了铣削试验,通过快速落刀装置获取了铣屑根,对绿色铣削Ti6Al4V时的切削变形进行了分析。试验结果表明:铣削变形随铣削速度vc和每齿进给量fz的增大而减小;水蒸汽和电离空气可减小铣削变形。The machinability of Titanium alloy Ti6A14V is poor, in this paper a new green cutting technology with water vapor and Ionized air as coolants and lubricants was proposed to achieve the aim of Efficient and green cutting for Ti6A14V. A set of milling tests using carbide tool YG6 were performed under dry cutting, oil emulsion, water vapor and I- onized air, respectively. The milling roots was obtained by quick-stop device and the milling formation was researched. The results of tests indicated that the Milling formation was decreased with milling speed and feed per tooth increased, the milling formation was reduced during water vapor and ionized air condition.
