摘要
车削过程中颤振导致的车削失稳会对机床和刀具寿命、加工效率和加工表面质量造成极为不利的影响。为了提高车削加工的效率和质量,对车削过程进行稳定性分析并获取无颤振车削条件成为了一项非常重要的研究内容。分析了颤振的产生机理,综述了车削过程的频域和时域稳定性分析方法,并回顾了锯齿形切屑驱动的车削失稳研究进展,总结了当前颤振分析尚存在的主要问题,并探讨未来的研究方向。
During the turning process,the instability caused by chatter will cause a very bad influence on the life of the machine tool and the cutting tool,the machining efficiency and the surface quality.In order to improve the efficiency and quality of turning process,it is a very important content to study the stability of turning process and obtain the condition of chatter free turning.In this paper,the mechanism of chatter is analyzed,the stability analysis methods of frequency domain and time domain in turning process are summarized,the main problem existing in the flutter analysis are summarized and the future research direction is discussed.
