摘　　要：针对钛合金整体结构件粗加工的插铣和侧铣工艺,从切削力、切削稳定性、切削温度等方面进行了切削实验和分析对比。实验结果表明,在相同切除率条件下,插铣的轴向切削力略大于侧铣的轴向切削力,而插铣作用力仅为侧铣的1/3;随着切削深度的增加,插铣刀具的振动比侧铣刀具的振动小,且切削过程稳定;插铣的切削温度要比侧铣的切削温度低。最后,以TC4钛合金整体叶盘通道开槽为例,进行了插铣验证。验证结果表明,插铣切削过程稳定,效率比侧铣提高了近1倍,刀具成本仅为侧铣的13%。The rough plunge milling and the traditional rough side mllhng process were pertormeci and compared from cutting force, cutting stability, temperature for the overall structure of the titanium alloy pieces. The experimental results show that in the same metal removal rate, the axial cutting force of plunge milling is slightly larger than that of side milling, while the active force in plunge milling is only 1/3 of that in side milling. With increasing of the depth of cut,the tool vibration of plunge milling is smaller than that of side milling, the cutting process is steadier, and the cutting temperature of plunge milling is lower than that of side milling. Finally, the experimental verification taking the passage slotting rough process of TC4 titanium alloy overall blisk as the example was carried on and the results show that plunge milling＇ s efficiency increases more than one time, the entire cutting process is steady; its cost is only 13% of that of side milling.
