切割工具和工件之间的相对振动在超精确钻石加工中的表面产生中起着重要作用。切割工具的高频振动对表面粗糙度误差具有重要影响，而机床结构的低频振动会影响数字误差。以前的相关研究主要集中于机床的第一模式频率振动。但是，很少讨论其多模频振动。在本文中，研究了机床的多模频振动及其对飞行中表面产生的影响。发现实验结果与模拟结果吻合很好。
Relative vibration between the cutting tool and the workpiece plays an important role in the surface generation in ultra-precision diamond machining. High-frequency vibration of the cutting tool has important influence on the surface roughness error, while the low-frequency vibration of machine tool structure affects the figure error. The previous related researches mainly focus on the first-mode frequency vibration of the machine tool. However, its multimode frequency vibration is rarely discussed. In this article, the multimode frequency vibration of the machine tool and its influences on the surface generation in flycutting are studied. The experimental results have been found to agree well with the simulation results.
