Analysis of springback phenomenon in a multistage precision cold forging process

Recommended Posts

Hello Forum users,

 

An automatic multi-stage precision cold forging process of a yoke was simulated with emphasis on springback phenomenon using an elastoplastic finite element method. The results are discussed below.

It was observed that the AFDEX predictions deviated from the experiment values by 16% in this example. 

 

Cheers from AFDEX Support Team !
