20.500.12556/RUL-149170 Laserska izdelava označevalnih ploščic za električne vodnike Laser production of marking plates for electrical conductors V diplomskem delu se obravnava lasersko označevanje na nerjavnem jeklu in vpliv osnovnih parametrov za črno oznako. Namen dela je iskanje optimalnih parametrov in laserskega sistema, ki zagotavlja dovolj kontrastne oznake. Oznake smo opravili z laserskim sistemom, sestavljenim iz vlakenskega laserja, skenirne glave, programskega vmesnika in pozicionirnega sistema. Na vzorcih smo naredili matrike iz oznak, kjer smo spreminjali moč laserja, dolžino trajanja bliska in prekrivanje. Eksperimenti so bili izdelani na vzorcih iz nerjavnega jekla AISI 304 in debeline 1 mm. Rezultate smo ovrednotili glede na kontrast in hrapavost oznak ter jih predstavili skupaj s parametri označevanja. Iz dobljenih rezultatov smo določili primerno oznako za našo aplikacijo in poiskali sistem, ki zagotavlja izdelovanje primernih črnih oznak. Diploma work presents laser markings on stainless steel together with the influence of basic parameters on black markings. In the thesis we tried to obtain the optimal parameters in laser system which ensures sufficient contrast markings. They were produced with laser system consisting of a fiber laser, laser scan head, laser system interface and laser positioning system. Samples were matrix-assisted meaning that laser power, laser light length and overlapping were changing. All the samples were performed on stainless steel AISI 304 1.5 mm thickness. Results were evaluated according to marking contrast and roughness and presented together with marking parameters. The results obtained enabled us to label our application as well as to search for the system that provides production of adequate black markings. vlakenski laser lasersko označevanje parametri označevanja nerjavno jeklo hrapavost oznake fiber laser laser marking laser marking parameters stainless steel mark roughness true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2023-09-05 08:31:01 2023-09-05 08:31:03 2023-10-06 16:56:17 0000-00-00 00:00:00 2023 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.795.8:621.375.826:669.14(043.2) 255802 165926403 29577.pdf 29577.pdf 1 BB37D94804823D300712CB6F47E7D54A b3d38dd0f7ca79b9791dd2a9d4ea8d43daf90336e6f2166e3af4918e224be27a c6760c32-4bb5-11ee-af86-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=173568 Fakulteta za strojništvo 0 0 0
