摘要
对一种二维椭圆振动辅助切削(EVC)装置的运动学特性进行分析,建立该装置刀尖轨迹的运动学模型,从理论上探讨该装置刀尖运动在一定激励下产生椭圆轨迹的可能性。同时实际加工出EVC装置,在相应的检测系统下测试该EVC装置的刀尖运动轨迹数据,利用测得的数据对运动学模型进行修正,并将修正后的模型输出值与实测值进行比较,验证了修正后模型的有效性。
Based on the kinematic analysis, the kinematic model of a 2D elliptical vibration-assisted cutting （EVC） device was established. The elliptical motion locus of the tool tip under certain excitation was theoretically illustrated. The actual EVC device was manufactured and tested by the detecting system, and the kinematic model was modified by the experimental data. The validity of the modified model was verified by the comparison between the calculated values by modified model and the experimertal data.
