Abstract

The countersinking process is consisted to enlarge a pre-hole using a conical punch in order to allow rivets and screws to sit flush with the surface of the assembled sheets. The geometry of the pre-hole had many effects on this process. The main goal of this study is to characterize the effects of the pre-hole geometrical parameters on the obtained countersunk hole. Their effects on the forming kinematics and the loads were investigated. A finite element model was developed using ABAQUS/Standard. The adopted model was performed with an elasto-plastic behavior and an isotropic hardening rule for the workpiece. A configuration with a maintained blank holder has been adopted for this study. The results from simulations analysis provided one good explanation for the complexity of the observed forming kinematics. The comparison between the simulations and the experimental results confirmed the validity of the adopted finite element model for predicting the loads and the final shape of the countersunk workpiece.
