Dinamika premočrtnega odrezavanja : magistrsko delo = Orthogonal cutting dynamic : master of science thesisBučar, Bojan, 1961-2012V delu je prikazan teoretično podprt način vrednotenja dinamičnih lastnosti signala komponent rezalne sile s pomočjo dinamičnega signalnega analizatorja pri premočrtnem odrezavanju lesnega tkiva s ... spremenljivimi obdelavnimi parametri.Narejena je analiza rezultatov vpliva smeri rezanja v območju med 90 do 0 stopinj in 90 do 140 stopinj, prsnega kota rezila od 15 do 30 stopinj, debeline odrezka od 0,2 do 0,8 mm in hitrosti rezanja od 0,19 do 0,56 m/s na dinamične lastnosti signalov komponent rezalne sile pri odrezavanju lesa različnih drevesnih vrst (Fagus silvatica L., Populus nigra L., Celtis zenkeri Engl., Detarium macrocarpum Harms, Manilkara fouilloyana Abrev. & Pellegr., Xylopia hypolampsa Mildbr. & Diels). Z naraščajočimi vrednostmi parametrov se ne glede na drevesno vrsto zmanjšuje verjetnost najpogostejše amplitude signala - rezalne sile, povečuje pa se moč energijskega spektra. Frekvence, pri katerih se pojavljajo izrazitejši vrhovi energijskih spektrov, so neodvisne od obdelavnih parametrov. Rezultati analiz signalov komponent rezalne sile v časovnem, amplitudnem in frekvenčnem prostoru kažejo na to, da je odrezavanje lesnega tkiva proces lokalnih izrazito naključnih porušitev tkiva v deformacijskem območju, ki ga lahko analiziramo zgolj s statističnimi metodami.Type of material - master's thesisPublication and manufacture - Ljubljana : [B.
