The so-called self-excited vibration occurs in the absence of any external force, that is, the vibration phenomenon that the straightener excites itself during the cutting process. The same self-excited vibration frequency will directly affect the processing process.

It can be seen from the analysis of the reasons that the cutting tool, the material of the cutter, the rigidity and the cutting speed are all the same, and the cutting width is the root cause of the self-excited vibration. The forced vibration is different. It is the vibration that is caused by various external influences. If the dynamic frequency and the straightener overlapgre.
