摘要
在机床切削颤振分析中首次考虑了模糊不确定性因素的影响，利用模糊数学分析方法详细论述了切削过程再生颤振的模糊稳定性分析问题，给出了模糊稳定性极限切削宽度集合的可能性分布及其置信区间表达式，最后依据本文的理论分析。
The effect of fuzzy uncertainty factors on the cutting chatter is studied. Using fuzzy mathematical analysis,the problem of fuzzy stability analysis of regenerative chatter with fuzzy interference is discussed in greater detail.The expression of possibility distribution and confidence interval in fuzzy stability cuttion domain is given.Fuzzy stability chart is drawn in suitable confidence level.
