用实验曲线分段讨论外圆纵向磨削稳定性的发生、发展规律。统计分析指出:纵向磨削中的临界颤振频率受诸因素影响,存在较宽的动态范围;振动旋向可用来判断磨削稳定性,是一项重要表面特征。
The experiment curve is used to discuss the occurrence and development regularity of the longitudinal grinding stability of the external circle. The statistical analysis shows that the critical chatter frequency in longitudinal grinding is affected by various factors and has a wide dynamic range. Vibration direction can be used to judge the grinding stability, which is an important surface feature.
