Resumen de Sound pressure as a tool in the assessment of the surface roughness on medium density fibreboard rip sawing process
Alfredo Aguilera, José Luis Barros
This research takes the option of using sound pressure signals to monitor the resulting surfaceroughness from rip sawing process of medium density fibreboards samples. Different cutting conditionswere evaluated, namely cutting speed and feed, giving as a variable the mean chip thickness, beingalso assessed the effect of the climb cutting and conventional cutting mode. The main results lead toconclude that the sound pressure was closely related to the variation of the mean chip thickness givingadequate levels of correlation with the surface roughness. A positive, linear relationship was observedbetween feed rate and surface roughness, as well as for sound pressure. The best surface quality wasachieved when climb cutting mode was applied. Then, the measurement of sound pressure results isa useful method to monitor MDF cut process, being possible to predict the surface roughness, as wellas the effect of the change of cutting conditions.
