Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling metal forming processes, such as those for steel or aluminum, face challenges in monitoring all relevant measured variables due to tool design and sensor limitations, leading to inefficiencies and increased scrap rates, as not all variables can be effectively measured in real-time, especially residual forming capacity parameters like elongation at break and tensile strength.
Innovation Solution
A method involving obtaining forming boundary conditions and material/process parameters from separate devices, using simulations based on finite element methods to determine measurement information, which specifies necessary measurements and sensor positions, thereby reducing experimental complexity and improving process control.

Engineering Contradiction Analysis
1Measurement precision
If multiple downlink channels and uplink channels are measured separately using conventional methods, then each channel's measurement accuracy is maintained, but the measurement time and system complexity increase significantly
Solution Approach 1:
The patent combines multiple channel measurements (downlink channels and uplink channels) into a single joint measurement process. The network device sends downlink reference signals while the terminal device simultaneously performs downlink channel measurement and uplink channel measurement based on the same reference signal, thereby reducing the overall measurement time while maintaining measurement accuracy through unified processing
2Measurement precision
If multiple channels are measured using separate conventional procedures, then measurement completeness is ensured, but the interaction and coordination between multiple channels deteriorate
Solution Approach 1:
The patent implements a universal measurement mechanism where a single downlink reference signal serves multiple measurement purposes simultaneously. The reference signal is used for both downlink channel measurement and uplink channel measurement, eliminating the need for separate reference signals and reducing the complexity of coordinating multiple independent measurement procedures

AI summary
The invention relates, inter alia, to a method for determining measurement information for a forming process of a metal part that is to be performed, in particular for steel or aluminum forming, the method being carried out by at least one second device (304). The problem of providing a method by means of which the forming process to be performed can be efficiently controlled such that the production of faulty metal parts or rejects is reduced or largely avoided is solved according to the invention in that the method comprises the following: obtaining forming constraints of the forming process to be carried out from a first device (302) at the second device (304); obtaining and/or determining material parameters of the metal part and/or process parameters of the forming process to be performed; performing and/or triggering the performance (130) of at least one forming simulation on the basis of the forming constraints and the material parameters and/or process parameters; determining (140) measurement information at least partly on the basis of the at least one forming simulation; and providing (150) the measurement information from the second device to the first device.
