Abstract. In recent years, there has been resurgence in the use of time waveform analysis technique. Condition monitoring personnel find the time waveform analysis process difficult and the technique is rarely used to its full potential. The key to the successful utilization of time waveform data consists in knowing when to use it. This paper details in practical terms how to set up, acquire and manipulate time waveform data for bearing condition monitoring. The paper continues to discuss the interpretation of the data including the time-frequency relationship, symmetry, and pattern recognition of common defaults.
