“…Depending on the operational characteristics such as cutting speed, depth of cut, and on the mechanical properties of wood species (density, moisture content, resin content) different dust and chips may be obtained, concerning their size distribution and physical properties [11].…”

“…The expected quantity by volume of dust and chips produced in the unit time is determined by the width and depth of cut and the feed speed. The quantity by mass (kg/s) is obtained by multiplying the volume with the wood density [11]:…”

“…Therefore, it is important to find a combination of processing parameters suitable for a minimum surface roughness. Furthermore, the surface roughness of wood is very complex and represents a superposition of morphological features, such as waviness, raised fibers, tool marks, wood anatomical voids, as well as possible processing surface defects, such as material detached from the surface [4][5][6][7][8][9]. In this respect, the most used roughness parameters such as Ra or Rz are not enough to give a complete picture of the origin of the different irregularities present on a processed surface.…”

The evaluation of surface quality after milling still represents a challenge due to the stratified structure of wood. In this paper, the surface quality of beech wood obtained by profile milling was analyzed differentiating between tool marks, fuzzy grain, and accidental surface gaps overlapped onto the deep anatomical cavities. The samples were milled at two rotation speeds, 3308 rpm (n1) and 6594 rpm (n2), and two feed speeds of 6.53 m/min (vf1) and 23.74 m/min (vf2). After the samples were cut, approximately 600 m of beech wood were further processed before measuring the surface quality again. The surface waviness measured by Wa increased more than double when the feed speed increased from vf1 to vf2. Rk increased with the feed speed (with the feed per tooth, fz, for a constant n, respectively) for n2 by a significant 57%. An increase in the rotation speed from n1 to n2 has reduced Rk, but the effect was not significant. The processing quality, Rk, measured at different depths did not differ statistically, in spite of the local differences in the cutting speed. The moment of measuring the surface roughness, such as immediately after sharpening or after a working period, influenced the surface quality. After the tool processed 600 m of beech material, the surface quality improved by 30%. The statistical analysis showed that the most important factor affecting the surface quality was the feed speed (implicitly fz, for constant n and number of cutters).

“…A megoldás így komplex szemléletet igényel, amely magában foglalja a tervezés, üzemeltetés és szabályozási kérdések adta rendszer energiafelhasználásra történő optimalizációját. A téma fontosságára tekintettel, a Soproni Egyetem kutatói angol nyelven foglalták össze vonatkozó kutatási eredményeiket(Magoss et al, 2022), melyek elméleti alapjai lehetnek a gyakorlati megoldásoknak.Por-forgács elszívórendszer és a munkahelyi légtér kapcsolataA faipari megmunkáló gépek esetében a forgácsoló megmunkálások során por-forgács keletkezik, melyet úgynevezett vegyes, vagy szívott rendszerű por-forgács elszívó hálózattal távolítanak el a megmunkálás helyéről.

A faipari por-forgács elszívó hálózatok tervezési, kivitelezési és üzemeltetési kérdései Magyarországon nem egyértelműen szabályozottak pedig komoly munkaegészségügyi probléma és túlzott energiafelhasználás jelenhet meg egy rosszul kivitelezett rendszer esetében. A Szerzők ismertetik a faiparra jellemző faporokkal kapcsolatos munkaegészségügyi problémákat, a por-forgács elszívó rendszerek javasolt tervezési feltételeit a munkaegészségügyi és energiafelhasználási szempontok figyelembevételével.
