20.500.12556/RUL-182896 Prediction of specific energy consumption in sustainable milling of Ti-6Al-4V with different machine learning models Research on eco-friendly and energy-efficient machining processes has gained significant importance within the domain of sustainable production. This study is focused on enhancing the energy performance and sustainability of the milling process. Four machine learning (ML) models, namely, multiple linear regression (MLR), support vector regression (SVR), Gaussian process regression (GPR), and adaptive network-based fuzzy inference system (ANFIS), were proposed to estimate specific energy consumption (SEC) in the milling of Ti6-Al4-V under two eco-benign cooling conditions: cryogenic and minimum quantity lubrication (MQL). Several statistical metrics, including normalized mean absolute error (nMAE), mean absolute percentage error (MAPE), normalized root mean square error (nRMSE), maximum absolute percentage error (maxAPE), coefficient of determination (R2), andWillmott’s index of agreement (IA), were employed to validate the performances of the ML models. A high level of agreement between the predicted and experimental SEC data for both the training and test datasets supports the reliability of the proposed ML models. Although the MLR model performed well, the results revealed that the other ML models demonstrated better overall performance. According to the statistical metrics, the models’ predictive performance improved in the following sequence: MLR, SVR, GPR, and finally ANFIS, which demonstrated the highest predictive capability. machine learning specific energy consumption sustainable machining strojno učenje specifična poraba energije trajnostna obdelava true false true Angleški jezik Slovenski jezik Članek v reviji 2026-05-27 13:32:01 2026-05-27 13:32:12 2026-05-28 04:33:38 0000-00-00 00:00:00 2026 0 0 18 str. issue 3, art. 266 Vol. 16 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.937:004.85 2075-4701 10.3390/met16030266 279565827 Cica,_Kramar...Prediction_of_specific....pdf Cica,_Kramar...Prediction_of_specific....pdf 1 137F94EF17D8A784CA15CE2666B9D922 2418ab6d45875c9aed97711891cb71556538df4c127e73b635f3893785a7db3f 85df8f19-59bf-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234545 https://www.mdpi.com/2075-4701/16/3/266 1 5ea8ea61-59bf-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234544 Fakulteta za strojništvo 0 0 0
