Experimental–Numerical Dataset for Springback Prediction in Air Bending with Additively Manufactured Polymer Tools

This dataset provides the experimental and numerical data supporting the results presented in the manuscript “An Experimental–Numerical Framework for Springback Prediction and Angle Compensation in Air Bending with Additively Manufactured Polymer Tools.” It includes raw tensile test data for DC04 steel sheets and FDM-printed ABS specimens, force–displacement data obtained from controlled air-bending experiments, processed flow curves used as input for finite element simulations, and numerical as well as experimentally measured bending angles after springback. The experimental data were obtained through uniaxial tensile testing in accordance with ISO 6892-1 and ISO 572-2and force-controlled air bending, while numerical simulations were performed using the Simufact.forming finite element software. Optical 3D scanning using a DAVID SLS-2 system was employed for geometric and angular measurements. The dataset can be reused for validation of numerical models, investigation of springback phenomena, and the design and assessment of additively manufactured polymer tools for sheet metal forming applications.本数据集为论文《增材制造聚合物模具空气弯曲中的回弹预测与角度补偿实验-数值框架》中的研究结果提供了实验与数值支撑数据。数据集包含DC04钢薄板与熔融沉积成型（Fused Deposition Modeling，FDM）打印的ABS试样的原始拉伸试验数据、受控空气弯曲实验获取的力-位移数据、用作有限元仿真输入的加工后流动应力曲线，以及回弹后的数值计算弯曲角度与实验实测弯曲角度。实验数据依据ISO 6892-1与ISO 572-2标准，通过单轴拉伸试验与力控空气弯曲实验获取；数值仿真采用Simufact.forming有限元软件完成。几何与角度测量采用DAVID SLS-2系统开展光学三维扫描。本数据集可复用于数值模型验证、回弹现象研究，以及面向金属板材成形应用的增材制造聚合物模具的设计与评估。
