SAF2205 bidirectional stainless steel is an excellent material for multiple corrugated diaphragms. It is necessary to study its stamping forming characteristics and provide a theoretical basis for stamping forming of multiple corrugated diaphragms. In this paper, the detailed V-bending process parameters are formulated. The effects of bending speed, relative fillet radius, temperature, and alignment time on spring-back behavior of SAF2205 bidirectional stainless steel are systematically studied to reveal the positive and negative spring-back mechanism. The range of process parameters suitable for stamping of SAF2205 bidirectional stainless steel was obtained. Article Highlights The detailed V-bending process parameters are formulated. The effect of SAF2205 parameters on the spring-back behavior was studied. The range of process parameters suitable for stamping of SAF2205 was obtained.

Spring back compensation is essential for accurate geometry of sheet metal components. In this paper the effect of process parameters namely sheet thickness, bend angle and tool travel rate on spring back in SS304 and C80 material sheets under V-bending is predicted by using finite element method and artificial neural network approaches. Total nine experiments were designed considering three process parameters, each with three levels, by using Taguchi`s L9 orthogonal array. The results obtained by ANN model are in good agreement with FEM model. This establish the robustness of ANN model for predicting spring back value and may be used an alternative to FEM model as the latter is more expensive and time consuming. The optimized value of sheet thickness, bend angle and tool travel rate are 2 mm, 80°and 6 mm ms -1 respectively for SS 304 material and 2 mm, 80°and 2 mm ms -1 for C80 material.

This study discusses the phenomenon of spring-back and spring-go in the bending kinematic forming using V-bending dies process and Electrolytic zinc-coated steel sheet (SECC/JIS G 3313) material. The zinc layer on the galvanized steel surface should not be damaged during the material forming process. The zinc layer on the galvanized steel sheet will affect the metal forming process. This study uses an experimental design with four input parameters, namely v-die opening L (mm), punch angle (degree), punch speed (mm/minutes), and bending force (kN). The smallest spring-back was obtained in the 4th test sample: the v-die opening of 35 mm, the punch angle of 40o, the punch speed of 30 mm/minute, and the bending force of 7.50 kN. The minor spring-back degree was 1.67o. Meanwhile, the smallest spring-go obtained in the second sample, namely the v-die opening of 30 mm, the punch angle of 50o, the punch speed of 40 mm/minute, and the bending force of 7.00 kN, the minor spring-go degree of 0.92o was obtained. These results show that the best spring-back degree for SECC/JIS G 3313 material is obtained when the bending process is performed with the v-die bending parameter of 30 mm, punch angle of 50o, punch speed of 40 mm/minute, and bending force of 7.00 kN.
