研究了外圆超精加工过程中的成圆和波瓣形成问题。根据超精加工过程的运动学，建立了一个模型来模拟瞬时的坯料去除和由此产生的工件轮廓。当连续工件旋转过程中的磨粒轨迹完全不同步时，模拟预测了在轴向振动频率与工件旋转频率之比为一半的情况下运行时的LOB声子，以及当该频率比为整数值时的最小去除，以便连续磨粒轨迹同相且不相交。实验验证了在半频比下出现波瓣，在全频比下减少了原料去除。

An investigation is reported on rounding and lobe formation during external cylindrical superfinishing. A model was developed to simulate the instantaneous stock removal and the resulting workpiece profile in terms of the kinematics of the superfinishing process. The simulation predicts a lobing phonomenon when operating at half ratios of axial stone oscillation frequency to workpiece rotational frequency when abrasive tracks during successive workpiece rotations are completely out-of-phase, and minimal removal when this frequency ratio is an integer value such that successive abrasive tracks are in-phase and do not intersect each other. The occurrence of lobes at half frequency ratios and reduced stock removal at whole frequency ratios were experimentally verified.
