Towards advanced control of manufacturing cells

Recent research in manufacturing increasingly focuses on energy efficiency, sustainable production, automation, and digitalization, driven by economic and environmental pressures. This progress is underpinned by digital technologies, advanced optimization methods, and smart manufacturing concepts, which collectively redefine the capabilities of modern production systems. Globalization and product individualization impose intensified competition, shortened lifecycles, and greater variability of workpieces. Conventional production systems cannot adequately respond to such dynamics. Within this context, autonomous machine tools constitute a key enabler, capable of independently planning, monitoring, and optimizing machining operations based on digital models and real-time data. This contribution reviews detailed solutions relevant for autonomous manufacturing and proposes a conceptual structuring of an autonomous manufacturing cell and its subsystems, outlines essential functional components, and discusses hierarchical control loops in the context of RAMI 4.0. Integrating industrial robots and mobile manipulators further enhances flexibility by automating material handling, thereby establishing machining cells with minimal human intervention.
