Obstojnost svedrov pri obdelavi avstenitnih jekel = Tool life in machining avstenitic stells : magistrsko delo

Dolinšek, Slavko

Avstenitna nerjavna jekla se zaradi specifičnih lastnosti, ki izvirajo iz strukture - velika žilavost, deformacijsko utrjevanje, slaba toplotna prevodnost - uvrščajo v skupino slabo obdelovanih ... materialov. Vrtanje teh jekel je še posebno težavno, ke je rezalni proces na konici svadra težko spremljati. Naloga podaja teoretičen in praktičen pristop k reševanju specifične problematike vrtanja avstenitnih nerjavnih jekel. Transformacija odrezka na rezalnih robovih svedra je raziskana s trenutno ustavitvijo rezanja. Iz izmerjenih vrednosti utrjevanja odrezka pa je postavljen realni rezalni model, ugotovljene najugodnejše geometrijske karakteristike vijačnega svedra in obdelovalni parametri za vrtanje avstenitnih nerjavnih jekel. Obstojnost svedrov je določenaa z merjenjem obrabe proste ploskve svedra in statističnim vrednotenjem eksperimentalnih rezultatov. Izračunane obstojnostne enačbe upoštevajo vpliv posameznih parametrov na obstojnost svedrov pri vrtanju avstenitnih nerjavnih jekel. Vnos podatkov v tehnološko banko podatkov in proizvodni obrat pa daje tudi praktično uporabnost rezultatov.
