20.500.12556/DKUM-96492 Multicriteria optimisation of machining operations using a spreadsheet model The rapid development of new materials and tools demonstrates the need for efficient and feasible machining processes. Modern production systems must guarantee sustainable, flexible, productive and high-quality production at low cost. Therefore, the combination of technological data with advanced software solutions is very important, especially when using complex CNC machining systems, where the reliability of the technological information is crucial, as simple measures can make a very positive contribution to the productivity achieved. When optimising the machining parameters, costs and machining time must be taken into account. The article deals with the optimisation of the turning process with a large number of influencing variables (machine, workpiece material, tool, cutting parameters, costs, etc.) and two objectives: the fastest possible machining (minimisation of machining time) and the lowest possible machining costs. The model is designed in an Excel spreadsheet and the multi-criteria optimisation is carried out using the approximation method. Step by step, we can find the optimal processing regime for each selected case. cost cutting parameters machining optimisation time stroški rezalni parametri strojna obdelava optimizacija čas true false true Sveučilište Sjever Angleški jezik Slovenski jezik http://tehnickiglasnik.unin.hr/ Članek v reviji 2026-01-14 11:18:48 2026-01-14 11:18:48 2026-01-15 03:10:12 0000-00-00 00:00:00 2024 0 0 str. 445-451 no. 3 Vol. 18 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-05-14 2024-05-22 2024-09-05 658.5:621.9 203707907 10.31803/tg-20240514150731 1848-5588 tj_18_2024_3_445-451.pdf tj_18_2024_3_445-451.pdf 1 FE55E7D2722D68F653641491AC3FFE41 a0e443c93ec198e2bdc2f6612626fb5cb040b32deffc1974207cc6c226e34c51 b5fc1e40-f132-11f0-8a93-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=201998 https://hrcak.srce.hr/319185 0 c119cb49-f132-11f0-8a93-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=201999 Fakulteta za strojništvo 0 0 0
