Abstract
In this study, a series of condition monitoring experiments on drill bits were carried out. Small diameter drill bit run-to-failure test rig was constructed and the prediction tests were performed. In the experiments, 10 small drill bits (1 mm ⌀) were tested until they broke down, while vibration data were consecutively taken in equal time intervals. After the reconstruction of phase space, correlation dimensions and metric entropies were found for each data set of drill bits. Moreover, fractal dimensions were computed by other two methods; box counting and Hausdorff measure. Finally, a comparison between these chaotic invariants was indicated.
