摘要

TB6 钛合金是航空制造领域承重结构件的重要材料，属于典型难加工材料。开展了TB6 钛合金铣抛喷组合工艺试验，研究了不同铣削参数对表面完整性的影响及精铣与喷丸工序间的耦合关系。结果表明，试件表面粗糙度主要受铣削每齿进给量fz 影响。 fz 0.2mm/z 时，组合工艺加工后，试件表面粗糙度值Ra 较低；fz 0.2mm/z 时，随精铣fz 提高，铣削硬化率下降，喷丸后的表面粗糙度提高；铣喷组合工艺条件下，铣削线速度vs 在20~40m/min 范围内，硬化率随vs 的升高而降低，喷丸区域表面粗糙度升高；vs 在40~50m/min 范围内，铣削硬化率升高，喷丸区域表面粗糙度降低。切宽ae 对试件硬化和表面粗糙度的影响不显著。铣喷组合工艺条件下的精铣参数优化结果为：vs=50m/ min，fz =0.2mm/z，ae=1.0mm。铣抛喷组合工艺条件下，可在低于0.4mm/z 范围内适当提高铣削每齿进给量fz。

Abstract

Titanium alloy TB6 is an important material in the field of aerospace manufacturing

and it is a typical hard-to-process material. Experiments were conducted to optimize the milling parameter of combined processes of milling

polishing and shot peening. The results indicated that surface roughness is mainly influenced by feed engagement (fz). When fz 0.2mm/z

the milling hardening is high and the surface roughness after shot peening was stable and correspondingly low. When fz 0.2mm/z

milling hardening declines and surface roughness after shot peening rises according to the rise of fz. When linear velocity vs is between 20m/min and 40m/min

milling hardening declines and surface roughness after shot peening rises according to the rise of vs. When vs is between 40m/min and 50m/min

milling hardening rises and surface roughness after shot peening declines according to the rise of vs. The influence of cutting width ae on hardening and surface roughness was not significant. The optimization results of milling parameters based on combined progresses of milling and shot peening are vs=50m/min

fz =0.2mm/z

ae=1.0mm. After polishing is added

feed engagement (fz) could be improved under 0.4mm/z.
