This study investigated the trajectory of a small-dimension drill bit in wood-based materials and used computer vision to determine the three-dimensional position of the hole. The results showed a good correlation between total deviation and initial deviation in medium-density boards and hardboards.
The aim of this study was to investigate the trajectory of a hole drilled using a small-dimension drill bit (0.5 mm) in wood-based materials. Computer vision was used to determine the three-dimensional position of the hole. Scans were made to a depth of 5 mm every 0.5 mm (access to subsequent layers was obtained by milling with three three-blade cutter with a diameter of 26 mm). The obtained results allowed us to determine the parameters of the obtained hole, allowing to correlate the quantities, such as deviations (initial, relative, total) and angle of relative azimuth. A good correlation (R-2 > 0.75) between total deviation and initial deviation for medium-density boards and hardboards can be found. The initial deviation of the drill determines the direction of the tool into the material and the initial deviation forces a specific direction of further deviation.
