The paper deals with the issue of chip extraction from the milling process in a CNC machining center. The paper aimed to compare the particle size distribution of dust generated in the milling process of natural wood (beech, oak, and spruce) and MDF on a 5-axis CNC machining center. The particle size distribution was evaluated using sieve analysis of samples from the total weight of the captured dust. The results showed that the processing of natural wood is mainly characterized by the formation of coarse dust fractions (2 mm - 1 mm sieves), while the processing of MDF was associated with the formation of fine dust fractions with a size below 100 μm. Another of the objectives was to compare the separation values on the fractional separation curves of selected mechanical separators and filters with the size distribution of dust particles and to propose a suitable separation technique that meets the criteria of "best available technique" (BAT) in the processing of natural wood and MDF, as well as to point out the creation of and the production of harmful dust fractions, which arise mainly during the processing of MDF. We intended to assess whether the introduction of the given technology with the given material mix will also require modifications on the side of the extraction device.

Descr. články - journal articles Language English Country Germany Annotation Airborne wood dust poses health and safety risks in the construction and furniture industry. The study verified whether the thermal modification affects the share of fine wood dust particles (< 10 μm) generated during spruce, oak, and meranti wood sanding. The experimental research involved nine material variants, including three wood species in three states: untreated, thermally modified at 160 °C, and thermally modified at 220 °C). To collect at least 200 g of each dust sample, a belt sander with P80 sandpaper and a belt speed of 10 m/s was used, along with a dust collector. The collected dust was then separated into fractions using a set of sieves with aperture sizes of 2000, 1000, 500, 250, and 125 μm. A laser particle sizer was employed to measure the sizes of dust particles in the under-sieve fraction (dust with particle sizes smaller than 125 μm). The under-sieve fraction was decomposed into three subfractions, with particle sizes: <2.5, 2.5-4.0, and 4.0–10 μm. Surprisingly the results indicate that sanding dust from thermally modified wood generates a lower average mass share of potentially harmful fine particle fractions than dust from untreated wood. Oak dust contained a higher mass share of fine particles compared to the spruce and meranti dust samples. Dust from thermally modified oak and meranti wood had a lower content of harmful particle fractions than dust from untreated wood. The average mass shares of these dust fractions for modified wood at 160 and 220 °C showed no statictically significant differences (p < 0.05). Conversely, spruce dust had a low content of fine fractions because spruce particles exhibit a more irregular elongated shape. The study considered the extreme temperatures of 160 and 220 °C used in the thermal modification of wood. Therefore, the above statements are assumed to be valid for all intermediate thermo-modification temperatures.

Descr. články - journal articles Language English Country Poland Annotation Long-term operation of pulse-jet filters for wood dust. The study specifies the value of flow resistance and separation efficiency of filter material during long-term use in pulse-jet filters for wood dust. The experiments were carried out for one type of material working in two different filtration installations in one furniture factory. The bags were obtained from the installations after working for 67, 133 and 272 days, respectively. All tests were performed on the pilot-scale test stand under identical filtration conditions. Studies have shown that long-term filter material use increases airflow resistance and improves filtration efficiency. The range of these changes depends on the operating conditions of the pulse-jet filters. The obtained results made it possible to determine the properties of the long-term use of filter materials in various filtration conditions.

Descr. články - journal articles Language English Country Slovak Republic Annotation The aim of the paper is to determine and compare the particle size analysis of chips resulting from the milling process of natural and heat-treated oak and spruce wood at different temperatures (160 °C, 180 °C, 200 °C and 220 °C). The individual percentages were divided according to the mesh size of the sieves into a coarse fraction using a mesh size of 2 mm and 1 mm, a medium coarse fraction with a mesh size of 0.5 mm and 0.250 mm and a fine fraction with a mesh size of 0.125 mm; 0.08 mm; 0.063 mm; 0.032 mm and the bottom of the screening machine, depending on the type of wood and the treatment temperature. When milling oak, the highest proportion of fine particles was recorded at a treatment temperature of 220 °C - 13.18 %. In this way, we can state that the milling showed the effect of a decrease in the mechanical properties of wood with increasing treatment temperature, which is more brittle. The percentage of the finest particles in spruce wood increases with increasing treatment temperature, from 0.53 % in the milling of natural wood to 11.29 % in the milling of heat-treated wood at 220 °C.

Descr. články - journal articles Language Slovak Country Slovak Republic Annotation Pojem ergonómia sa čoraz častejšie objavuje vo všetkých odvetviach výrobnej aj nevýrobnej sféry, od výberu detského ergonomického nábytku do domácnosti, až po zariaďovanie priemyselných komplexov. Jednoducho prichádza doba, v ktorej si človek začína uvedomovať zdravotné následky, príčinami ktorých sú zlé usporiadanie pracoviska, nesprávna poloha v sede alebo, okrem iného, nevhodná farba na pracovisku. Cieľom ergonómie je navrhnúť a vytvoriť také riešenia, ktoré by boli na pracovisku, ale aj v domácnosti optimálne a mali pozitívny vplyv na zdravie ľudí v súlade s ekonomickou efektívnosťou. Na stredných odborných školách ale i základných školách v predmete Technika ako aj pri rôznych praktických činnostiach sa už od absolventov očakáva, že sa budú vedieť správne postaviť k danému stroju a budú si ho vedieť aj správne pripraviť či už z pohľadu bezpečnosti pri práci (rôzne ochranné kryty a pod.) ako aj z pohľadu ergonómie a samotného prostredia. Cieľom príspevku je poukázať na základné princípy ako eliminovať príp. znížiť na minimum záťaž na človeka v pracovnom procese a poukázanie na riziká a choroby z povolania, ktoré môžu vzniknúť nesprávne navrhnutým a zariadeným pracoviskom.

Descr. príspevky v zborníku - proceedings papers Language English Country Bulgaria Annotation Products made of thermally treated wood have different requirements for the quality of the created surface, depending on their application area. While we can make do with a milled surface for tiling and flooring, we have more sophisticated products such as garden furniture, etc. that require final surface sanding. The article focuses on the effect of thermal modification on the quality of the ground surface. It compares the surface quality of the ground surface of native woods oak, spruce and meranti with their thermally treated variants at temperatures of 160°C, 180°C, 200°C and 220°C. Quality is examined on a surface sanded with a belt sander with 80-grit sandpaper. It points to the fact that the process of a thermal modification slightly impairs the quality of the ground surface. However, when evaluating a surface on a larger scale, the quality of the created surface is influenced mainly by the "natural roughness of the wood" by the opening of anatomical elements of the wood, which are the primary source of increased roughness.
