Abstract:V lesni industriji je plemeniti furnir izdelek z visoko dodano vrednostjo. Tehnološki proces izdelave je razmeroma dobro poznan, vendar na kakovost izdelanega furnirja in posledično ceno vpliva veliko tehnoloških parametrov izdelave, največji vpliv pa ima kakovost hlodovine. V raziskavi smo preučili vpliv optičnih napak bukove (Fagus sylvatica L.) hlodovine in vpliv klimatskih razmer v fazi sušenja rezanega furnirja na valovitost površine. Raziskava je bila opravljena v industrijskem okolju. Rezultati kažejo, da je bilo procentualno največ valovitega furnirja izrezanega iz razpokanega hloda (71 %), najmanj pa iz ukrivljenega hloda (20 %). Kakovostno razvrščanje furnirja je bilo ročno in po subjektivnem kriteriju izkušenih kontrolorjev iz industrije. Kljub njihovim izkušnjam pa lahko subjektivna ocena vpliva na natančnost razvrščanja in s tem na rezultate raziskave. Zato smo preučili tudi možnost integracije 3D kamere za merjenje valovitosti furnirja in razvrščanje furnirja v kakovostne razrede.

Title:Valovitost bukovega rezanega furnirja
Abstract:In wood industry, decorative veneer is a product of high added value. Although the technological process of sliced veneer is well known, its quality and price depend on many technological parameters of production, particularly on the quality of logs. The research, which was focused on the influence of visual defects of beech (Fagus sylvatica L.) logs and the impact of climatic conditions in the drying phase of sliced veneer on the surface veneer waviness, was conducted in an industrial environment. The results indicate that the largest share of waved veneer was cut from cracked logs (71%) and less from curved logs (20%). The veneer was sorted manually by experienced controllers from this branch of industry. Their subjective criteria can affect the accuracy of classification of veneer and, consequently, the research results. Therefore, the possibility of using 3D camera for measuring veneer waviness and grading the veneer into quality classes was examined.
