Abstract

Suvremeni trendovi u razvoju alatnih strojeva usmjereni su prema povećanju stupnja
njihove autonomnosti. Pritom se najvećim dijelom ističu moduli za indirektni nadzor
obradnog procesa. Odvalno glodanje može se smatrati tehnički zahtjevnijim u odnosu na
ostale obradne procese zbog kinematike procesa u kojoj alat i obradak rotiraju istovremeno,
što posljedično otežava integraciju odgovarajućih senzora i akvizicijskog sustava. U prvom,
uvodnom poglavlju diplomskog rada, opisan je proces odvalnog glodanja. S drugim su
poglavljem prikazane tipične izvedbe odvalnih glodalica. Zatim, u trećem poglavlju je
opisana postojeća odvalna glodalica u Laboratoriju za alatne strojeve, na temelju koje je
predloženo novo konstrukcijsko rješenje mjerne naprave za prihvat obratka na odvalnoj
glodalici. U četvrtom poglavlju je opisano novo konstrukcijsko rješenje mjerne naprave koja
je projektirana na način prikladan za ugradnju senzora vibracija i odgovarajućeg akvizicijskog
sustava. Posljednje, peto poglavlje, donosi zaključak na temelju prethodno navedenog.

Abstract (english)

Contemporary trends in the development of machine tools are directed towards to
increasing the degree of their autonomy. The most prominent are modules for indirect control
of the manufacturing process. Hobbing could be considered as a more technically challenging
process than other machining processes due to the kinematics of the process, in which the tool
and workpiece rotate simultaneously, what consequently makes it difficult to integrate the
compatible sensors and the acquisition system. In the first, introductory chapter the hobbing
process is described. The second chapter outlines typical designs of hobbing machines.
Afterwards, in the third chapter, an existing hobbing machine from the Machine Tools
Laboratory is described, on the basis of which a new structural design solution of the
clamping device for the gear hobbing machine is proposed. In the fourth chapter, a new
structural design of the clamping device, that is designed to be suitable for mounting vibration
sensors and the appropriate acquisition system, is described. The last, fifth chapter brings a
conclusion based on the previously mentioned.
