What is it about?

This paper aims to address the springback control problem to improve the efficiency and accuracy of metal curved surface forming. A basic computation approach is proposed based on the DeepFit model to calculate the springback value in 3D surface bending. A multi-model fused bending parameter generation framework is devised to implement the advanced springback computation approach.

Why is it important?

To address the sample data shortage problem, we put forward an advanced approach by combining a deep learning model with case-based reasoning (CBR). The advanced springback computation approach includes four steps - surface data preprocessing, CBR-based model matching, convolution neural network-based machining surface generation, and bending parameter generation with a series of model transformations.
