| Abstract: | This paper makes AR model and recognized natural frequncy of machine tool with time series ana- lysis method in the states of continuous and noncontinuous steady cutting. In comparing the obtained result of sine wave excitation method and FFT analysis method, the advantage of recognizing natural frequency of machine tool in the state of noncontinuous steady cutting is described. |
