Sustainable manufacturing process in wood machining / Alena Očkajová, Martin Kučerka, Adrián Banski. -- The aim of this paper is to point out the importance of sustainability also in production processes. For the process of longitudinal sawing of beech, beech with a healthy false heart and spruce, we characterized the most important inputs and outputs of the given process based on the scheme from the viewpoint of sustainability. The aim of our investigation was the use of 2 different saw blades SB1 and SB2 and their effect on the granularity of sawdust from the viewpoint of dust particles ≤ 100 μm, which are dangerous for the operating personnel, because dust from hardwoods in particular is included among carcinogens. The proportion of individual sawdust fractions was obtained by sieve analysis. When sawing with the SB2 disc, 56.76 % ÷ 76.0 9% of dust particles ≤ 100 μm are produced compared to SB1 within the selected variants. When comparing woods, the proportion of dust particles ≤ 100 μm for spruce for all variants ranged from 7.95 ÷ 15.09 %, for beech from 10.52 ÷ 24.03 %, which is quite a high percentage, since it is a carcinogen. By choosing the right tool, we can reduce the share of the dust particles ≤ 100 μm, which is dangerous for the working environment.
