20.500.12556/RUL-114150 Optimizacija procesnih parametrov struženja keramike Optimization of turning process parameters of ceramics Magistrska naloga obravnava obdelavo keramike s procesom struženja. Zagotoviti je potrebno visoko kakovost površine, kjer ima najpomembnejšo vlogo radij robu obdelovanca. Gre za keramiko, ki se uporablja kot zaščitni element električnih komponent in naprav in katere prevladujoč proces obdelave v industriji zaenkrat ostaja brušenje. V magistrski nalogi smo s pomočjo metode načrtovanja eksperimentov (DOE) pripravili načrt izvedbe preizkusov, pridobili empirične modele, ki kažejo vpliv posameznih vhodnih parametrov na merjene odzive procesa ter na osnovi kriterijev določili optimalne parametre, ki prinašajo želene odzive procesa. Pokazali smo vpliv vhodnih parametrov; radija orodja, podajanja ter rezalne hitrosti; in na izhod procesa: kakovost obdelane površine keramike. Eksperimente smo izvedli pri dveh pogojih, z uporabo emulzije in brez nje. Ugotovili smo, da optimiranje vodi do izboljšanja kakovosti končne površine in stabilnosti procesa odrezavanja. In the master thesis the processing of ceramics with the turning process has been researched. High quality of the surface where the workpiece edge radius plays the most important role must be ensured. It is a ceramic used as a safety component for electrical components and appliances, and the dominant process of machining in the industry so far remains grinding. In the master's thesis, with the help of the design of experiment method (DOE), we prepared a test execution plan, obtained empirical models that show the influence of individual input parameters on measured process responses and based on criteria determined optimal parameters that yield the desired process responses. We showed the influence of the input parameters; tool radius, feed rate and cutting speed; to process output: quality of the treated ceramic surface. The experiments were performed under two conditions, with and without emulsion. It has been found that optimization procedure can lead to significant improvement in surface quality and process stability. keramika struženje metoda načrtovanja eksperimentov radij robu parametri obdelave kakovost površine ceramics turning design of experiment method edge radius process parameters surface quality true false false [N.
