In this paper, the practical applicability of data-driven methods is demonstrated through a representative case study of a hydraulic press used in sheet metal bending operations. Based on this system, a comprehensive monitoring and analysis framework was developed, combining systematic process data acquisition with regression-based machine learning models to enable advanced insight into press behavior under diverse operating regimes. The experimental investigation covers a wide range of scenarios, including varying forming forces, hydraulic cylinder velocities, and controlled simulation of friction effects in the cylinder guide system. Five key process parameters were identified as dominant inputs and used for a comparative evaluation of several regression approaches. The results show that linear regression, Support Vector Machines, and Gaussian Process Regression achieve superior predictive performance, with coefficients of determination exceeding R2 = 0,99 across all evaluated operating phases. At the same time, the analysis confirms that simpler models offer significant advantages in terms of training time and computational efficiency, which is particularly important for real-time industrial applications. The proposed approach enables continuous detection of operational deviations, achieves up to a 95% reduction in hydraulic cylinder response error, and establishes a solid foundation for real-time adaptive control strategies. By integrating machine learning models into the control and monitoring architecture, the presented methodology contributes to increased robustness, responsiveness, and transparency of hydraulic forming systems. As such, it supports the development of intelligent, data-driven manufacturing solutions aligned with the principles and objectives of Industry 4.0 and Industry 5.0Umetna inteligenca (UI) in strojno učenje vse bolj poganjata razvoj sodobnih izdelovalnih sistemov, pri katerih je zanesljivo delovanje neposredno povezano z natančnim poznavanjem trenutnega stanja strojev. V prispevku je predstavljena praktična uporabnost teh pristopov na primeru hidravlične stiskalnice pri upogibanja pločevine. Na osnovi tega primera je bil razvit napredni krmilni sistem, ki združuje zajem procesnih podatkov v realnem času in uporabo regresijskih modelov za spremljanje obratovalnih parametrov stiskalnice v različnih delovnih režimih. Eksperimentalni del je bil zasnovan tako, da obsega širok spekter scenarijev z variabilnimi obremenitvami, hitrostmi hidravličnega valja ter nadzorovano simulacijo trenja v vodilih valja. Z uporabo petih ključnih procesnih parametrov je bila izvedena primerjalna analiza več pristopov strojnega učenja, pri čemer so linearna regresija, metoda podpornih vektorjev in Gaussovo regresijsko modeliranje imeli najvišjo natančnost napovedi (R2 > 0,99). Rezultati so pokazali, da enostavnejši modeli omogočajo hitrejše učenje in učinkovitejše napovedovanje. Razviti pristop omogoča sprotno zaznavanje odstopanj v delovanju, zmanjšanje napake odziva hidravličnega valja do 95 % ter predstavlja osnovo za uvedbo adaptivnega krmiljenja v realnem časuTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
