Prediction of Springback in Long Channels [PDF]
Acta Metallurgica Sinica (English Letters), 2015 Sheet metal forming is one of the most preferred manufacturing processes in automotive and aerospace industries. However, due to increase in fuel prices and more stringent environmental regulation, these industries are facing many challenges to meet the criteria. Due to this, many efforts in design and manufacturing were considered and presented. Those

A Comparative Study on the Production of a Hat Profile by Roll Forming and Stamping
Advanced Engineering Materials, Volume 25, Issue 15, August 2023., 2023 The age‐hardenable aluminum alloy AA7075 allows the application of different temper states (e.g., T6, W, and O) and therefore different process routes for roll forming and stamping of a high‐strength hat profile. Within the process routes fundamental differences are observed in terms of process design, product quality, productivity, and energy ...

Springback prediction and elasticity modulus variation
Procedia Manufacturing, 2019 Abstract Angular precision of air bending is directly related to the precision of the calculated punch stroke, which is computed in order to achieve the required sheet profile before the springback. The calculated springback accuracy depends on the elasticity modulus which, as it is well-known, decreases with increase of plastic prestrain. During the
