20.500.12556/RUL-170083 Zasnova in numerična analiza priprave za merjenje sil pri odrezovanju Design and numerical analysis of cutting forces measuring device Avtomobilska industrija se stalno razvija in prilagaja potrebam ter zahtevam trga. Zaradi želje po izboljšanju učinkovitosti in podaljšanju življenjske dobe odrezovalnih orodij smo razvili pripravo za merjenje sil med odrezovalnim procesom struženja. Osnovo zasnovanega sistema predstavlja triosno piezoelektrično zaznavalo sile, s čimer bomo zagotovili bolj učinkovito delovanje procesa in podaljšali življenjsko dobo orodja. Izpeljali smo celotni proces zasnove priprave za merjenje odrezovalnih sil, tj. od koncepta do končnega funkcionalnega izdelka, ki je moral izpolnjevati zahteve vgradnih mer obdelovalnih strojev. Predstavili smo posamične komponente zasnovane priprave in njihovo funkcijo. Po zaključeni fazi konstruiranja smo postavili numerični model merilne priprave z metodo končnih elementov. Izvedli smo analizo padca občutljivosti zaznavala sile, ki je posledica vgradnje zaznavala v pripravo. Predstavili smo merilno opremo in eksperimentalne metode ter merilno pripravo eksperimentalno preizkusili. The automotive industry is undergoing continual transformation in response to evolving market demands. In pursuit of enhanced operational efficiency and extended service life of cutting tools, a novel device for the measurement of cutting forces has been developed. Central to this system is a three-axis piezoelectric force sensor, which facilitates improved monitoring of the cutting process and contributes to increased durability of the cutting tool. The development process encompassed all stages—from conceptual design to the realisation of a fully functional prototype—while adhering to the dimensional constraints imposed by machine tool installations. The design and functionality of the individual components comprising the measuring device are systematically presented. Upon completion of the design phase, a numerical model of the device was constructed using the finite element method (FEM). This enabled an analysis of the sensitivity drop experienced by the force sensor due to its integration within the mechanical structure of the device. Furthermore, the measurement equipment and experimental methodologies employed are described in detail. The device was subjected to experimental testing to validate its performance and to assess its practical applicability in force measurement during cutting operations. elektronsko zaznavalo sile avtomobilska industrija razvoj naprave za merjenje sile metoda končnih elementov obdelava z odrezovanjem naprave za merjenje rezalne sile electronic force sensor automotive industry development of a force measurement device finite element method machining device for measuring cutting forces true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-07-02 12:58:02 2025-07-02 12:58:03 2025-07-03 04:43:07 0000-00-00 00:00:00 2025 0 0 XX, 54 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.9:621.317:519.6(043.2) 271139 241117443 39100.pdf 39100.pdf 1 CD33634EEC6F212ABF191188EE5C634F 6531ca73baf448d6ea7b228aa2dd0af01f71f5e7ef8b3f86452dd022122d2b30 87b38476-5731-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=212007 Fakulteta za strojništvo 0 0 0
