【 摘 要 】

This study aims to find the development for the evaluation of the surface roughness by the Acoustic Emission (AE) method with air blowing. We paid attention to the AE wave due to air blowing on the specimen plate with different surface roughness. The relationship between the AE wave and surface roughness of specimen plates was investigated. As the result, there is large and continuous difference in the Root Mean Square (RMS) value of their AE waveform. The RMS value decreases by increasing of the surface roughness of specimen plates. It suggested that this characteristic has the possibility to establish a new method of nondestructive surface roughness testing.
