摘　　要：设计了一种新型组合成形铣刀:将3把单角铣刀,通过端面开十字沟槽的方式组合成一把铣刀,解决了加工多角度坡口零件的工艺难题;选用指数瞬时切削模型,运用Deform 3D切削仿真软件,选择不同切削参数:切削转速n(300、475、600 r/min),背吃刀量a_p(0.5、1、2 mm),模拟铣刀精加工时零件切削力大小的变化。在转速600 r/min、切削深度为1 mm左右时,获得较为理想的切削参数,为实体加工提供依据。该组合成形铣刀的设计,提高了加工效率,为组合角度零件的加工提供思路。A new type of combined forming milling cutter was designed:three single-angle milling cutters were combined into one milling cutter by the way of opening grooves on the end face to solve the technical problems of machining multi-angle groove parts.Selecting the exponential instantaneous cutting model,using the Deform 3D cutting simulation software,choosing different cutting parameters,such as cutting speed was 300,475,600 r/min,cutting depth was 0.5,1,2 mm,the change of cutting force under fine milling was simulated and more ideal cutting parameters were obtained at the speed of 600 r/min and cutting depth of 1 mm.It provides basis for the machining of multi-angle parts.
