Drill holes deflection determination for small diameter bits in wood-based materials

The growing interest in wood accessories has focused scientific research attention on cutting with small diameter tools. A problem that may arise when drilling is the phenomenon of wandering – hole not made designed place. difficulty studying drill holes (0.5 mm to 0.9 mm) due automatic measurement. development an appropriate methodology allow for observation this without need high-class hardware and expensive software. This article presents results tests carried out nearly 500 samples various wood-based materials (high-density fiberboard (HDF), medium-density (MDF), chipboard, plywood) terms usefulness OpenCV computer vision library determination wandering.
