Abstract
In this priority programme funded by the DFG, the scientific fundamentals of process-integrated property control of forming processes are researched and novel approaches for property-controlled forming will be designed and validated. Due to the current developments in production technology, the property control of forming pro-cesses is to be regarded as an emerging field. The cooperation with control engineering provides the opportunity for forming technology to design controllable forming systems based on advanced control engineering methods and to devise the sensors and actuators required for property control in the system design. This collaboration is expected to yield fundamental knowledge about the design of resilient, microstructure- and property-controlled forming processes. Projects included are as follows: (1) Feedback Control of Surface Properties of Flat-rolled Semi-finished Products Based on Online-roughness Measurements of the Strip Surface, (2) Controlled Flow Spinning of Cylindrical Components for Production of Workpieces with a Defined Strain Hardening, (3) Development of a Flexible Isothermal Bar Forging Process for the Property-controlled Manufacturing of Turbine Blades from High-temperature Materials, (4) Thermomechanical Ring Rolling with Predictive Property Control, (5) Controlled Solid-liquid Transition During Casting Rolling With the Help of Soft Sensors, (6) Multi-variable Closed-Loop Control with Feedforward Control of Forming Product Properties - Fundamentals and Application to Punch-Hole-Rolling, (7) Property Control During Spinning of Metastable Austenites, (8) Property-controlled Process Design of Freeform Bending Considering Material Properties of the Semi-Finished Product, (9) Product Property Controlled Multi-stage Hot Sheet Metal Forming.
