Abstract
U ovom diplomskom radu razmatraju se specifičnosti koje se događaju kod obrade odvajanjem čestica nehrđajućeg čelika. Razmatra se trošenje alata kod obrade tokarenjem. Određene vrste nehrđajućih čelika pogodnije su za obrađivanje. Kod obrada nehrđajućeg čelika koje su pogodnije za obrađivanje, trošenje alata je manje. S obzirom na veliki utjecaj površinskog trošenja oštrice alata na kvalitetu konačnog proizvoda, potrebno je što više smanjiti trošenje. Poznavanje procesa trošenja kod obrade... More odvajanjem čestica nastoji se smanjiti taj proces. Parametri obrade također utječu na postojanost alata. U ovom radu ukazano je na nedostatke koji se dešavaju tijekom obrade sa različitim parametrima obrade. Kod eksperimentalnog dijela izabran je nehrđajući čelik X8CrNiS18-9, obrada tokarenjem, određeni su parametri obrade. Analizirani su različiti utjecaji na reznu oštricu koji se događaju tijekom obrade. Mjerena je temperature rezne oštrice nakon obrade, kvaliteta obrađene površine, te je provedena analiza istrošenosti alata. Na osnovi dobivenih rezultata mjerenja i prikazanih slika rezne oštrice zaključeno je da je u slučaju utjecaja parametara obrade na zagrijavanje rezne oštrice, na srednje aritmetičko odstupanje Ra, te samu istrošenost rezne oštrice značajni utjecaj imala dubina rezanja. Što je dubina obrade bila veća mjereni parametri su se povećavali. Less
Abstract (english)
This thesis discusses the specifics that occur during processing by separating the stainless steel particles. The tool wear during turning is also considered. Certain types of stainless steels are more suitable for processing. While processing stainless steel, which is more suitable for processing, the tool wear is low. Given the large impact of surface wear of the tool blade on the quality of the final product, it is necessary to reduce the tool wear as much as possible. This can be done... More by knowing the wear process in the particle separation process. Machining parameters also affect the tool life. In this thesis, the shortcomings that occur during processing with different parameters are pointed out. In the experimental part, stainless steel X8CrNiS18-9 was chosen, processed by turning and the parameters of processing were selected. Different impacts on the cutting blade during processing were analyzed. The temperature of the cutting blade and the quality of the machined surface were measured after processing, and a tool wear analysis was perfomed. Based on the obtained measurements and shown images of the cutting blade, it was concluded that the cutting depth, in case of the influence of machining parameters on the heating of the cutting blade, on the arithmetic mean deviation Ra, had a significant impact on the wear of the cutting blade, The greater the processing depth, the higher the measured parameters increased.
