dc.description.abstractДа би се извршила обрада материjала, кртих по своjоj природи, неопходно jе прећи са нивоа макро на ниво микро обраде. Са друге стране, то jе неизво- дљиво без jасно дефинисаних механизама микро резања коjи важе за поменуте материjале. Докторска дисертациjа усмерена jе на формирање механизама ми- кро резања мермера Плави ток и гранита Jошаница и Буковик. Предложени механизми експериментално су потврђени методама утискивањем утискивача при статичком деjству силе утискивања и микро резања (гребања). Испитиван jе утицаj фактора коjи потенциjално делуjу на процес микро резања, међу ко- jима су: брзина микро резања, дубина продирања алата и вредност радиjуса заобљења врха алата...sr
dc.description.abstractIn order to process the brittle material, it is necessary to move from the macro to the micro cutting level. On the other hand, this is unfeasible without clearly defined micro cutting mechanisms applicable to these materials. The doctoral dissertation is focused on the formation of micro cutting mechanisms of marble Plavi tok and granites Joˇsanica and Bukovik. The proposed mechanisms were experimentally confirmed by the methods of Static indentation and Micro cutting (Scratching). The influence of potentially affecting factors on the micro cutting process was examined, among which were: micro cutting speed, depth of cut and tool tip radius. A mechanism of the Static indentation method was proposed and subsequently experimentally confirmed on the basis of which, on the one hand, the formation of an indent in the ductile mode was created, while on the other hand, the development of the cracks that lead to the brittle separation of the material in the brittle fracturing mode was explained...en
