20.500.12556/RUL-113738 Sustainability assessment of advanced machining technologies Ocena trajnosti naprednih tehnologij odrezavanja Efficient cooling and lubrication techniques are required to obtain sustainable machining of difficult-to-cut materials, which are the pillars of aerospace, automotive, medical and nuclear industries. Cryogenic machining with the assistance of lubricated Liquid Carbon Dioxide (LCO2) is a novel approach for sustainable manufacturing without the use of harmful water-based metalworking fluids (MWFs). In case of unavoidable use of MWFs under high pressure, such as turning finishing processes of difficult-to-cut materials, the pulsating high pressure delivery of MWFs prolongs the tool life and enables the control over chip length to prevent surface damage of high value-added parts. In this paper, sustainability assessment of both advanced principles was carried out, considering overall costs and operational safety. Experimental tests were executed on difficult-to-cut materials in comparison to conventional flood lubrication. For both techniques, longer tool life compared to flood lubrication was observed additional cleaner production and higher part quality led to reduced long-term overall costs. These advanced machining technologies are also operation safe, proving to be a sustainable alternative to conventional machining. cryogenic machining high pressure machining sustainability cost assessment risk assessment kriogeno odrezavanje visokotlačno odrezavanje trajnost stroškovna analiza analiza varnosti true false true Angleški jezik Slovenski jezik Članek v reviji 2020-01-30 08:05:37 2020-01-30 08:05:41 2022-08-26 03:47:16 0000-00-00 00:00:00 2019 0 0 Str. 671-679 no. 11/12 Vol. 65 Nov./Dec. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.9(045) 0039-2480 10.5545/sv-jme.2019.6351 16944155 762116 RAZ_Sterle_Luka_2019.pdf RAZ_Sterle_Luka_2019.pdf 1 78C248DFC80B99552CBD30B7FBAF9A6E f3426c67debfd24842f7da0d14be5b719292bd93f42988de5f012d3692afc6bb 26168ad7-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125840 https://www.sv-jme.eu/sl/article/sustainability-assessment-of-advanced-machining-technologies/ 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125839 Fakulteta za strojništvo 0 0 0
