The continuous chips cause problems in the automation for cutting process due to the difficulty of chip disposal. In order to solve these problems, the proper chip forms are required as a precondition for control of the chip forms. In this study, the relationships between the peak frequency and chip breaking frequency are investigated with the tool/workpiece thermocouple, the accelerometer and tool-dynamometer. Based upon the experiments, the following results are obtained. (1) The dynamic components of electromotive force exactly reflect the characteristics of the chip breaking, and the chip breaking frequencies exist below 200 Hz. (2) If chip breaking is not regular, the power of peak frequency gets lower in magnitude and wider in width. (3) The brittle material is hard to observe the frequency of the chip breaking.
