摘要
In this article, a new controllable and near net low-stress bar fine-cropping system was proposed and developed by combined using the stress concentration effect of the prefabricated V-groove and the propagation crack. The bar fine-cropping experiments were successfully carried out using a new proposed cropping load control strategy. Although the level of the stress intensity factor range Delta K greatly influences the cropping time and the cross-section quality, the cropped-billets can be directly used for the precision forging industry without additional machining.
