“…In their work, aiming to widen the application of the fineblanking process, the heat-assisted fine-blanking process of AISI 304 stainless steel grade was performed. The cutting of a dog-bone shape component showed that the increase in temperature was beneficial for the final quality of the fine blanked component, being 250ºC the optimal temperature for a cutting quality improvement [3].…”

Abstract. Many tribological tests have been developed in the last decades to emulate real cold forging processes at laboratory conditions and to obtain friction coefficients at different process conditions. In this paper a new tribotester is designed and numerically validated to reach extreme contact conditions, high normal contact pressure and surface enlargement, for warm temperature testing of lubricants starting from material in the form of thick sheets or precuts. The numerical simulations prove that this is possible by the use of a combined bending and ironing test.

“…Therefore, some materials need to be spheroidized and annealed before fine blanking to improve their plasticity [5]. According to this, Zheng et al [6] used heat-assisted fine blanking to process the parts. This will potentially be applied to high-strength materials.…”

High forming force is often needed when high-strength and low-plasticity materials are processed by fine blanking. Too high forming force increases the load of the die and greatly increases the risk of die failure. If the forming force is reduced, the material will fracture prematurely, which will lead to poor quality parts. Aiming at this problem, a new force variation load fine-blanking technology is proposed in this paper. During the loading process, the forming force does not remain constant but changes with the blanking stroke. A 2D finite element fine-blanking model was established for the TC4 material. The mechanism of force variation fine blanking is also revealed. This paper proposes a method to design the loading route of the forming force with variable load. This method combines finite element simulation with neural network and a multi-objective genetic algorithm. Finally, the application of variable load fine blanking production and the application of traditional fine blanking production parts are verified by the experimental method. The same results are obtained from both simulation and experiment. 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.

“…They introduced an annular trough at a die to enhance the quality of the shear zone. Another study by Zheng et al [4] focused on analyzing the sheared surface quality by subjecting stainless steel plates to different temperatures. They observed that a temperature increase up to 250°C could complete the shear zone.…”

The backing plate plays a crucial role in drum brakes, pushing the brake shoe against the drum for effective vehicle braking and road safety. Manufactured from steel sheets, it exhibits properties akin to a composite material, with characteristics varying based on directionality. The backing plate's profile features a continuous series of arcs, making the fine-blanked edge quality contingent on the arc radius. This research delved into fineblanked manufacturing through a combination of experimentation and simulation to discern the impact of the arc radius on edge quality. Employing a scanning electron microscope for edge quality investigation and benchmarking the finite element model against it, the study ensured a comprehensive understanding. The wellaligned finite element model served as input data for training an artificial neural network (ANN), specifically engineered to accurately estimate backing plate edge quality. This ANN is anticipated to be instrumental in designing future steel plate profiles boasting multiple arcs, offering precision in the manufacturing process for enhanced edge quality.
