Abstract. The advantage of (incremental) cold forming processes is that, in addition to the component geometry, the mechanical and physical properties can also be positively influenced. Appropriate control during the forming process is necessary to produce components with a defined geometry and defined, optimized product properties. To produce components with defined (graded) strain hardening by flow-forming a sensor for measuring the strain hardening was developed. Based on the measurement of magnetic permeability and magnetic anisotropy, control instructions are derived and forwarded to an actuator. Numerical simulation with Simufact Forming is used to evaluate the overall system and analyze the optimization of the product properties. In addition to the simulation of the flow-forming process, a virtual sensor for the strain hardening is applied based on the measurement of the experimental investigations. A subroutine was used to automatically adjust the roller feed within the simulation so that components with predefined hardening could be produced. The FE model is further used to optimize the real sensor position and functionality.
