摘　　要：通过TB6钛合金的侧铣加工试验,研究了工艺参数对钛合金加工表面完整性的影响规律。试验结果表明:每齿进给量的变化对加工表面形貌和粗糙度的影响最大;增大每齿进给量和铣削宽度,表面残余压应力有所增大,残余应力影响层变深,材料的硬化深度和硬化程度也有所增大;每齿进给量和铣削宽度的变化对塑性变形层的深度影响较小。By the experiments of flank milling of TC4 titanium alloy, the influence of the milling param- eters on machined surface integrity is investigated. The results show that the surface roughness and surface topog- raphy is affected most by the feed per tooth. By increasing the teed per tooth and milling width, the residual stress of surface is enhanced： the layer of residual stress is deeper. The hardening depth and hardening degree of the material becomes more. Changing the feed per tooth and milling width makes very little difference to the depth of plastic defornaation layer.
