Effect of Wood Grain Direction on Acoustic Emission during Routing
The purpose of this study was to investigate the causes of changes in acoustic emission(AE)signals corresponding to changes in grain orientation in routing.The angle between the cutting direction and the grain orientation has strong influence on the acoustic emission and the surface quality of wood.The results showed that the acoustic emission signal reached the strongest value when the angle was 0° and weakest when the angle was 90°.When the intensity of acoustic emission signal increased,the surface roughness was found to decrease.These results show acoustic emission could be used to monitor the quality of wood surfaces during various cutting conditions.
