| 摘 要： | 论述了机械加工过程中 ,刀具与工件之间的平面振动———椭圆运动 ,可以分解为任意两个互相垂直方向上的谐振动 ,推导出这两个谐振动之间的相位差即是振型耦合切削颤振的诊断参数 ;同时以车削、镗削为例建立了机械加工工艺系统发生振型耦合颤振时的加工曲线方程 ,并分析了颤振对机械加工表面几何形状的影响

| Abstract: | This paper indicates that during the machining, the plane vibration ellipse movement between cutter and workpiece can be resolving along two arbitrarily direction perpendicular to each other,and deduces that the phase difference is diagnostic parameter on the self excited vibration of oscillation mode coupling in machining.What's more, by quoting turning and boring as examples,the equations of machining curve are established as the self excited vibration occurring in the machining system and the effects on machining surface of self excited vibration shape are analyzed in this paper. |
