Abstract
ABSTRACT This paper aims at the influence of drilling conditions (feed rate and material type) upon the coordinates deviation (deviation from the nominal location) of holes in wood-based materials: high-density fiberboard (HDF), medium-density fiberboard (MDF), and hard fiberboard (HB). These were tested with drill bits of 0.5, 1.0, 2.0, and 3.0 mm. Coordinates deviation was measured with computer vision-based scripts. The conclusion obtained is as follows: drill coordinates deviation increases with feed rate and material hardness. Tool diameter influence is less obvious due to two factors: its slenderness and difficultness in the hole initiation process. The results obtained are generally in line with other works on micro-drilling and can be used as references for other wood-related works.
