Chatter 解析에 對한 非線形 理論 = Analysis of Nonlinear Chatter Theory

다국어 초록 (Multilingual Abstract)

The chatter analysis has been studied by many authors using non-linear theory.
In this study, the stability chart was obtained experimentally in lathe turning, and was compared with the result of chatter analysis by non-linear theory qualitatively.
From experimental results, it was verified that the stability of cutting process is affected by the depth of cut in the following manner. Keeping the rotational speed of workpiece constant, as the chip thickness is increased from zero, the stability can be distinguished by three ranges; (a) unconditionally stable range, (b) conditionally stable range, (c) unstable range. In the conditionally stable range the system is stable for small disturbances but unstable when these exceed a certain level.
When the chatter occurs, the amplitude initially increases and stabilized itself at a finite level. This phenomenon agree well with the analysis of non-linear theory qualitatively.
