![]() ![]() during the process execution, is tremendously characterised by noise and fluctuations revealing a stochastic nature. reflected by measures such as forces, deflections, travels, vibrations etc. Models do reflect reality as best as their design and structure may appear, but in many cases, they are based on simplifying assumptions and abstractions. Today, design and operation of manufacturing processes heavily rely on the use of models, some analytical, empirical or numerical i.e. It is found that the variable load fine blanking process can greatly reduce the load of the die on the premise of ensuring the quality of fine-blanking parts. The same results are obtained from both simulation and experiment. ![]() Finally, the application of variable load fine blanking production and the application of traditional fine blanking production parts are verified by the experimental method. This method combines finite element simulation with neural network and a multi-objective genetic algorithm. This paper proposes a method to design the loading route of the forming force with variable load. The mechanism of force variation fine blanking is also revealed. A 2D finite element fine-blanking model was established for the TC4 material. During the loading process, the forming force does not remain constant but changes with the blanking stroke. Aiming at this problem, a new force variation load fine-blanking technology is proposed in this paper. If the forming force is reduced, the material will fracture prematurely, which will lead to poor quality parts. ![]() Too high forming force increases the load of the die and greatly increases the risk of die failure. High forming force is often needed when high-strength and low-plasticity materials are processed by fine blanking. ![]()
