【 摘 要 】

Pre-laminated particleboard is a wood based composite extensively used in the furnitureindustry. Drilling is the most common machining process which prepares the panels for joining usingtwist/helical drills in the absolute majority of cases. The point angle of the drill bit and the feed speedduring drilling play a major role in gaining a good surface quality and minimizing the delaminationtendency of the pre-laminated particleboard. The objective of this study was to measure and analyzethe influence of the two above-mentioned factors on the processing quality, evaluated by de size ofdelaminations, both, at the entrance side and the exit side of the drill bit. To assess the defect, twoparameters were used: the delamination factor and the effective area of delamination. The resultsshowed that, in general, the combination of small point angle with low feed rate minimizes thedelamination of pre-laminated particleboard panels at drilling.
