20.500.12556/RUL-148994 Karakterizacija kinematike rezalnega orodja pri ultrazvočnem vzbujanju Characterization of cutting tool kinematics in ultrasonic excitation Zaključna naloga na začetku vsebuje teoretično predstavitev varistorjev in materialov iz katerih so izdelani. Prevladuje varistorska ZnO keramika, katero smo v nalogi tudi preučili. Poleg ZnO keramike smo opravili še kratek pregled industrijskih keramik na splošno. Izvedli smo analizo odrezavanja industrijske keramike do sedaj in pregledali prednosti in slabosti najpogostejših postopkov. Naša problematika je v pridobitvi ustrezne topografije površine, kjer ne dosegamo željene hrapavosti površine samo z običajnim struženjem, saj si želimo oprijemljivosti metalnega sloja aluminija. Rešitev tega problema je v naknadnem struženju čelne površine s pomočjo ultrazvočne asistence. Le to bomo v tej zaključni nalogi popisali z matematičnim modelom, ki bo služil za nadaljnjo rabo priprave ustrezne željene topografije. Zadevo je možno aplicirati tudi na druge materiale, ne le keramiko. The final paper starts with a theoretical presentation of varistors and the materials they are made of. The predominant material is ZnO ceramics, which are also examined in the assignment. In addition to this type of ceramics, a general brief overview of industrial ceramics is given. We have carried out an analysis of the cutting of industrial ceramics to date and reviewed the advantages and disadvantages of the most common processes. Our problem is to obtain a suitable surface topography, where we do not achieve the desired surface roughness by conventional turning alone, as we want the adhesion of the aluminium metal layer. The solution to this problem lies in the subsequent turning of the face surface with the assistance of ultrasonic assistance. In the thesis, we will describe this process with a mathematical model, which will be used for further preparation of the corresponding desired topography. The solution can also be applied to other materials, not only ceramics. varistor keramika ultrazvočno struženje topološki model topografija varistor ceramics ultrasonic turning topological model topography true false false [L.
