The values of all sizes obtained from the microscope measurements ranged over a wide range of all sizes between 3-1000 μm. Chips with sizes < 100.0-10.0 μm were the most prevalent, accounting for 50% and 47% of the total sizes present in the oak and spruce samples, respectively. The presence of chips <10.0 μm in size was present in oak samples 37% and in spruce samples 33% of the total number of chips. Chips of larger sizes were present in 13 % of the oak samples and 20 % of the spruce samples. The study of sizes below <10.0 μm showed that, based on medians, the most frequently occurring splinter size was 5.43 μm diameter for both species equally. In both samples, the sizes ranged from 3.43 to 9.71 μm. The study of dimensions below <100.0-10.0 μm showed that the most frequently occurring dimensions based on medians were chips with a diameter of approximately 30 μm for oak and chips with a diameter of approximately 28 μm for spruce.

Descr. články - journal articles Language English Country Slovak Republic Annotation In the article, we want to point out the still existing safety and health risks in woodworking operations, the essence of which lies in processing of non-homogeneous materials such as wood, with anisotropic properties and the occurrence of natural wood defects, manual feed of the workpiece into the cut, tools with a large number of cutting edges and high cutting speeds, manual handling of loads, but also in many cases in the irresponsible approach of the employees or employers themselve to the OHS. Failure to address or avoid these risks leads not only to injuries, but long-term work in this environment to occupational diseases, especially hearing loss, diseases of the musculoskeletal system, etc. Although the legislation covers all areas in terms of OSH, its implementation in practice is lengthy and not always adequate. The basis for characterizing the existing safety and health risks was the manual "Risk Assessment Basics - Good for You, Good for Your Company", Check list for Woodworking. Based on the description, it is obvious that the safety risks in woodworking are known, but in many operations they tolerate, and due to health risks, minimal attention is paid to manual handling of loads and ergonomics, the neglect of which contributes significantly to diseases of the musculoskeletal system.d URL Link na zdrojový dokument Public work category AFD No. of Archival Copy 54824 Catal.org.

Descr. články - journal articles Language English Country Poland Annotation Design and comparison of a suitable separation technique during the machining process in a CNC machining center. 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 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.
