Abstract
AGUILERA, Alfredo and ZAMORA, René. WOOD MACHINING PROCESS MONITORING OF BLACKWOOD (ACACIA MELANOXYLON) WITH ACOUSTIC EMISSION TECHNIQUE AND HIS RELATIONSHIP WITH RESULTING SURFACE ROUGHNESS. Maderas, Cienc. tecnol. [online]. 2007, vol.9, n.3, pp.323-332. ISSN 0718-221X. http://dx.doi.org/10.4067/S0718-221X2007000300011.
Wood machining parallel to the grain (90-0 direction) of Blackwood was performed using piezo-electrical transducer to record the acoustic emission (AE) signals generated during the cut process, considering the type of wood (heartwood and sapwood), and the relationship with surface roughness (Rz). A good relationship it was found between cutting conditions and acoustic emission signals, where an increase of the chip thickness results in a major consumption of cutting energy. Also, it was detected an increase of AE signals with the change of wood type, passing from sapwood to heartwood (increase of density). Finally, a good relationship it was found between surface roughness (Rz) and acoustic emission (AE)
