Smart FE-Based Tool Design in Cold Forging

In cold forging, the forming tool takes a key role as it determines accuracy and efficiency of forming process. The present study focuses on the FE based analysis of the influence of die material, interference within prestressing and die splitting on the stress state in and the elastic behaviour of the forming tool. The results reveal a great influence of the workpiece material and the tool layout on the outcome of the forming process and the corresponding tool stresses.
