摘　　要：钛合金整体叶轮是通道类复杂零件,在传统铣削粗加工流道过程中铣刀由于悬伸较长,容易发生变形和振动,切削效率较低。采用插铣加工整体叶轮流道,铣刀沿刀具轴向进给,铣刀变形和振动较小,因此可采用较大的铣削宽度和进给量,切削效率较高。建立了插铣加工钛合金整体叶轮流道的仿真模型,通过正交试验研究了铣削速度、铣削宽度和每齿进给量对切削力的影响规律,并建立了回归经验公式。结果表明,铣削宽度对铣削力的影响最为显著,铣削参数对插铣三向切削力影响程度由高到低均为a_e>f_z>v_c。可通过适当增加每齿进给量提高切削加工的效率。The titanium alloy integral impeller is a complex tunnel type component.In the traditional milling process of rough machining the tunnels,the milling cutter is prone to deformation and vibration due to its long overhang,resulting in low cutting efficiency.Using plunge milling to process the tunnel in alloy integral impeller,the milling cutter feeds along the axial direction of the tool,resulting in less deformation and vibration of the milling cutter.A larger milling width and feed rate can be used,resulting in higher cutting efficiency.A simulation model was established for the machining the tunnel in titanium alloy integral impeller by plunge milling.The influence of milling speed,milling width,and feed rate per tooth on cutting force was studied through orthogonal experiments,and a regression empirical formula was established.The results show that the influence of milling width on milling force is most significant,and the influence of milling parameters on the three-dimensional cutting force of plunge milling is in the order of ae>fz>vc.The efficiency of cutting can be improved by appropriately increasing the feed rate per tooth.
