20.500.12556/RUL-145038 Analiza vpliva radija rezalnega robu na obrabo in obstojnost rezalnih orodij pri struženju nerjavnega jekla X5CrNi18-10 Analysis of the cutting edge radius influence on tool-wear and tool-life of cutting tools in turning stainless steel X5CrNi18-10 V magistrski nalogi je analizirana obdelovalnost avstenitnega nerjavnega jekla X5CrNi18-10 z vidika ustreznosti odrezkov in obstojnosti orodja. V uvodnem poglavju so opisane teoretične osnove, ki pomagajo pri razumevanju problema. V nadaljevanju pa so predstavljeni eksperimentalni sistem in vsi koraki praktičnega raziskovalnega dela. Najprej smo izvedli eksperiment, kjer smo preverili vpliv radija rezalnega robu in geometrije različnih lomilcev rezalnih ploščic na obstojnost orodja, nato pa še eksperiment, pri katerem smo optimizirali proces struženja glede na lomljivost odrezkov. Kot rezultat eksperimentalnega dela smo lahko določili najboljšo rezalno ploščico in njene optimalne parametre za naš proces grobega struženja. This master's thesis analyzes the machinability of austenitic stainless steel X5CrNi18-10 from the aspect of chip adequacy and tool life. The introductory chapter describes the theoretical foundations that help with the understanding of the problem. In the following, the experimental system and the course of the practical research work are presented. First the experiment where we checked the influence of the cutting edge radius and the geometry of different cutting inserts on the tool life was carried out. Followed by an experiment in which we optimized the turning process in terms of the chip breakability. As a result of the experimental work, we were able to determine the best cutting insert and its optimal parameters for our rough turning process. struženje radij rezalnega robu obstojnost orodij nerjavno jeklo lomljivost odrezkov turning cutting edge radius tool life stainless steel chip breakability true false false [E.
