| description | Pre-laminated particleboard is a wood based composite extensively used in the furniture
industry. Drilling is the most common machining process which prepares the panels for joining using
twist/helical drills in the absolute majority of cases. The point angle of the drill bit and the feed speed
during drilling play a major role in gaining a good surface quality and minimizing the delamination
tendency of the pre-laminated particleboard. The objective of this study was to measure and analyze
the influence of the two above-mentioned factors on the processing quality, evaluated by de size of
delaminations, both, at the entrance side and the exit side of the drill bit. To assess the defect, two
parameters were used: the delamination factor and the effective area of delamination. The results
showed that, in general, the combination of small point angle with low feed rate minimizes the
delamination of pre-laminated particleboard panels at drilling. |
