Analiza vpliva tehnologije odrezavanja ZnO keramike z definirano geometrijo na končno kakovost izdelkov
Jaka Dugar, Franci Pušavec
Doktorska disertacija
Oznake: disertacije;odrezavanje;keramika;ultrazvočna oscilacija orodja;obdelovalnost;kakovost;hladno napraševanje;
Doktorsko delo obravnava problematiko obdelovalnosti ZnO keramike iz vidika zagotavljanja ustrezne kakovosti končnega izdelka, visokonapetostnega varistorja. Ključna identificirana karakteristika za pravilno delovanje je stanje roba diska in adhezijska napetost naknadno nanešenega aluminijastega slo ...

Oznake: ZnO varistorji;optimizacija parametrov obdelave;struženje;formiranje odrezkov;ZnO varistors;machining optimization;turning;chipping;accelerometer;FFT plotting;3D topography;
The sintered zinc oxide (ZnO) electro-ceramics are a brittle class of hard-to-cut materials such that shaping them with the post-finishing operations necessitates careful handling and precision machining. The conventional machining approach using the grinding and lapping processes represents limited ...
