Springback is a common defect caused by elastic recovery in the plastic forming process, which can cause formed workpiece to deviate from target shape. The purpose of this paper grasp influence law process parameters on springback deviation so as optimize reduce springback. Taking Y-profile research object, such horizontal bending radius, vertical transition zone length, radius roller dies, and...

One of the biggest challenges in automotive industry focuses on weight reduction in sheet metal forming operations, in order to produce a high quality metal part with minimal cost production. Stamping is the most widely used sheet metal forming process; but its implementation introduces several difficulties such as springback and failure. A global and simple approach to circumvent these unwante...

Predicting the springback angle has become major production problem among tube benders. Springback is where on a mandrel-less rotary draw bending tends to bounce back after being bent when clamps are released. Accurately predicting crucial for effective bending. Machine learning (ML), popular prediction approach, was applied functions such as or function approximation, pattern classification, c...

The recently developed Spring Back Reflector has low stiffness in the deployed configuration. A general method of stiffening this type of reflector without changing its folding properties is presented. The stiffening is achieved by adding a conical skirt around the edge of the dish; this skirt snaps elastically when the dish is folded. The paper concludes that it is possible to design spring ba...

A validated numerical model for in-plane stress/strain prediction is essential in understanding the deformation behaviour of sheet metal forming process, in particular, asymmetric deep drawing of advanced high strength steel sheet. In this work, the Yld2000-2d anisotropic yield criterion integrated with the initial homogeneous anisotropic hardening model was employed to describe the complex mat...
