Analiza tehnoloških in konstrukcijskih parametrov za izdelavo rezkalnega orodja : diplomski projekt = Analysis of technological and constructional parameters for milling tool manufacturing : B. Sc. thesis
Gabrovšek, Mihael
Raziskovali smo vpliv tehnoloških in konstrukcijskih parametrov rezkalnega orodja za odrezovanje lesa v prečni smeri (0° - 90°). Odrezovali smo zračno suho bukovino, kjer smo spreminjali ...orientiranost tkiva (0°, 30°, 60° in 90°), prsni kot rezila (10°, 20°, 30°, 40° in 50°) ter debelino odrezka (0,05 mm, 0,10 mm in 0,15 mm). Za vsako kombinacijo smo naredili dva reza, nato pa smo izmerili profil novo nastale površine. Iz izmerjenega profila smo izračunali parametre za vrednotenje hrapavosti površine: Ra - aritmetična srednja vrednost hrapavosti, Rz - srednja globina hrapavosti, Rq - standardni odklon, Rsk - poševnost, Rku - sploščenost in parameter krivulje nosilnosti. V raziskavi smo ugotovili, da je najboljša kakovost površine pri odrezovanju s prsnim kotom 40°, najmanjši debelini odrezka ter orientiranosti tkiva 90°, kar ustreza radialni površini. Iz navedene raziskave sledi, da je pri obdelavi bukovine v prečni smeri (0° - 90°) smiselno uporabiti namensko izdelano rezkalno orodje z večjimi prsnimi koti, kot jih imajo standardna na trgu dobavljiva rezkalna orodja (okrog 20°)
