In the expanding field of hot sheet metal forming and metal bulk forming, there is a growing demand for fully three-dimensionally tailored microstructural properties. Achieving predefined geometries with these tailored properties necessitates advanced control mechanisms throughout the process chain, which includes heating, forming, and cooling. The control architecture must be configurable and extendable to accommodate new geometries, microstructural distributions, and materials. This requires an adaptive algorithm that can manage locally and temporally differential thermo-mechanical effects in real-time, based on parameters from a comprehensive database of materials, geometries, and microstructures. The research focuses on the integration of measurement techniques with adaptive control processes to enhance hot metal forming of functionally graded materials. The goal is to achieve targeted three-dimensional microstructures in complex shapes while optimizing process cycle times within a customizable control framework. The thesis emphasizes adaptive control strategies within a flexible architecture for an innovative thermo-mechanical production process that utilizes induction heating to create specific spatial and temporal temperature distributions, along with combined metal forming and heat extraction processes. This flexible control architecture ensures consistent quality in dynamic processes and allows for the incorporation
