Characterization of Sound Signals in No-load Planer

Some sound will be produeed in process of planer operation,and it has the characteristics of itself.In this paper,we investigated and analyzed the sound signals arisen during no-load planer operation.Using the technique of digital signal processing including the methods in the domain of time,magnitude and frequency,we obtain their characteristics in each domain.We are going to identify and diagnose the process of planning in the further investigation.
