摘　　要：机械加工中工艺系统的振动破坏了零件的加工精度。刀具与工件之间的冲击力是引起振动的主要原因之一。通过对带有三维复杂槽型的波形刃铣刀片与平前刀面铣刀片铣削力和铣削振动的对比试验、铣削力的有限元数值模拟,表明带有三维复杂槽型的波形刃铣刀片铣削力小,铣削过程中引起工艺系统的振动较平稳。可以断言,优化刀具的结构与几何参数可有效地减小铣削过程的振动现象。Vibration of process system destroy machining accuracy of work piece during mechanical cutting.Impact force between cutter and work piece is main factor of vibration.Milling force test and milling vibration test of wave-edge milling insert with three-dimension complex groove and plane rake face milling insert were done.Numerical simulation of finite element of milling force was carried out.Research result indicated that milling force of wave-edge milling insert with three-dimension complex groove is smaller than that of plane rake face milling insert.Vibration which wave-edge milling insert bringed about was tranquility.It is predicated that vibration phenomenon must be diminished effectively during milling by optimizing cutter constructure and geometry parameter.
