In most cases of wood or wood-based materials processing the chips produced during machining are considered wastes, therefore no high attention is put on their quality. On the other hand it is very important, from technological and hygienic reasons, to remove chips from the cutting zone. The efficiency of the chips removal strongly depends on their mass and geometry. Theoretical shapes and dimensions of particles produced during peripheral milling are well known from the literature. However, depending on the machined material, the real shape and size of chips may be diametrically different from theoretical ones. In this research a method involving digital image analysis was involved to verify the real shape of chips produced in up- and downmilling. Measured chips from wood-based materials like particleboard was found to be extremely different from theoretical shapes expected. This was mainly due to high heterogeneity of the material.
Keywords: chips geometry, peripheral milling, particleboard machining
