The sleeve riveting method is the fastening process by which the plate parts are fastened with bolt and nut formed from the sleeve by using the swaging tool. The plastic flow into the thread grooves of a bolt occurs in the sleeve in the fastening process, and the sleeve becomes a nut. A series of experiments on the sleeve roveting process were carried out in the plane strain condition, and the plastic flows in the sleeve were measured by the visioplasticity method. Then, the effects of shape of the pressing face of the swaging tool on the plastic flow in the sleeve, punch-stroke curve and material filling in the grooves were investigated. Furthermore, optimum shape of the pressing face of the swaging tool was determined by the present investigation.
