车削加工表面振纹的成因及对策分析

Analysis of the causes and countermeasures of turning surface vibration ripples

振纹是在机械加工中工件表面常见的一种现象,振纹的出现对工件表面的加工质量、加工精度以及一些使用性能产生了一定的影响。因而通过对车削加工中出现的各种振纹形状的成因进行分析,找出问题的根源,并提出解决方法,以消除或减少振纹的出现。

Chatter is a common phenomenon in the surface of workpiece in machining, and the emergence of vibration rip-ples has produced certain effect on machining quality, machining precision and some performance of the surface of work-piece. Thus through the analysis of causes of various vibration pattern appearing in turning process , this paper tries to findout the root of the problem, and proposes solutions to eliminate or reduce the occurrence of vibration ripples.
