Effects of Cooling Conditions on Surface Integrity during Side-milling of TC4 Alloy

  • 摘要: 通过实验对比研究TC4钛合金铣削加工过程中不同冷却条件对其加工表面完整性的影响规律。研究结果表明:在相同的铣削参数下,乳化液冷却条件下加工表面的粗糙度值和显微硬度值均比在干切削条件下小;在乳化液冷却和干切削两种条件下的加工表面残余应力均为压应力;随着铣削速度、每齿进给量和铣削宽度的增加,在乳化液冷却条件下的残余应力绝对值逐渐增大,而在干切削条件下,残余应力绝对值逐渐减小;在乳化液冷却和干切削两种条件下,铣削参数中铣削深度对表面完整性的影响最小。
